Isra-Mart srl news:
Failure to secure some form of deal to help make new ships more carbon efficient could see the International Maritime Organisation (IMO) lose its status as the industry's guiding body, according to a senior executive at one of the world's largest shipping companies.
Jacob Sterling, head of climate and environment at Maersk, told BusinessGreen the UN body has to come away from a meeting in July with agreement on preliminary steps towards cutting shipping's carbon emissions or risk seeing its negotiating role supplanted by the UN's climate change secretariat, the UNFCCC.
"In July [the IMO] is discussing and trying to agree a global efficiency standard for new ships – it's a first step, it's not radical or highly ambitious," he said. "But it is make or break for the IMO if it wants to play a role in the future of shipping."
The IMO has overseen the slow progress of negotiations designed to agree how to reduce emissions from the sector, which account for about four per cent of global emissions and are predicted to increase exponentially as global trade expands.
However, the body denied that the outcome of July talks, known as MEPC 62, would decide its future.
"The Kyoto Protocol says that countries should work through the IMO to address shipping emissions and I don't see that changing," an IMO spokeswomen told BusinessGreen. "We hope to get some sort of agreement in July, but until we have that meeting its impossible to speculate. If nothing is agreed, other organisations may decide to take specific action, but we cannot comment on what they decide to do."
The EU has threatened to bring shipping into its Emissions Trading Scheme (EU ETS) from 2013 if a substantive deal is not agreed by the end of this year, increasing pressure on the IMO to move beyond technical improvements which do not address current vessels that could spend another 30 years on the ocean.
An IMO task force is meeting at the end of March to discuss potential market mechanisms, the outcome of which will be fed into the July talks.
Sterling insisted he was hopeful that some form of deal would be done in July, but insisted that ultimately a global agreement would be needed to stop individual regions implementing separate policies.
"The problem arises when there is one system in Europe, another in the US and a different one in Australia," Sterling said. "Then companies have to spend much too much time in administration rather than reducing CO2 emissions. We would like to see a global deal – a piecemeal approach all over the world would not be desirable."
Maersk ordered 10 new container ships this week that promise to substantially reduce emissions and fuel consumption, and Sterling is sure that the company's efforts to cut CO2 would see it profit from emissions regulations if applied globally.
"Regulations would be a benefit for us because we have already taken to investing to reduce CO2 emissions," he said. "With or without legislation it is good business for us to reduce costs and improve environmental performance... as bunker prices are high and continuing to rise."
In related news, South Korea, a country that also envisages demand increasing for energy-efficient, low-carbon vessels, today announced it would spend 300 billion won (£165m) over the coming decade to develop technology for "green" ships.
Maersk's order of 10 Triple-E ships, with an option for 20 more, from Korean firm Daewoo may prove the first of many orders for the country's seven shipyards after the government set a target of $50.9bn (£31.5bn) in shipbuilding orders this year, 35 per cent more than 2010.
South Korea's Ministry of Knowledge Economy added in a statement that two thirds of the new investment would come from government funds, with the remainder sourced from the private sector.

Isra-Mart srl:Google-backed firm promises to Transphorm AC:DC technology
www.isra-mart.com
Isra-Mart srl news:
Google has led a $20m funding round to support a US startup that promises to extend the range of electric cars and increase the amount of electricity produced by solar panels.
Google joined with other investors to help raise a total of $39m for Transphorm, a California-based firm which claims its technology can reduce – by up to 90 per cent – the energy lost from converting the alternate current (AC) that comes out of conventional sockets to the direct current (DC) that powers most electrical goods.
Around 10 per cent of energy lost in the US dissipates as a result of inefficient converters, such as the phone chargers that heat up as they charge devices.
Google said Transphorm's technology had the potential to save enough energy to supply the whole west coast of America if adopted across the country.
The company said that saving electricity wasted during conversion should make electric vehicles go further by eliminating the need to cool electric motors, while also improving the output of solar panels and limiting energy waste in buildings.
Slashing the energy bills of companies with vast datacentres is another potential benefit, making new investor Google a natural customer.
At the launch event at Google's headquarters in Mountain View, California, Transphorm chief executive Umesh Mishra said the company's technology made use of semiconductor material gallium nitride, often used in LED lighting, rather than the silicon that is typically used in converters.
"The current solution, which is based on silicon, is a solution which has reached its limit in high-voltage power conversion," he said. "We can't eke any more efficiency out of this technology. The time is now to do something different and affect the 10 per cent of wasted energy that occurs in power conversion."
With funding from Google Ventures, Google's venture capital arm, and a number of investment houses, Transphorm expects to launch products later this year, initially targeting computer data markets.

Isra-Mart srl:Huhne faces heat from solar review critics
www.isra-mart.com
Isra-Mart srl news:
The battle between the government and the solar industry looks set to intensify after energy and climate change secretary Chris Huhne today offered a defence of his department's decision to launch a fast-track review of incentives offered to large solar installations.
Writing in the Western Morning News and Western Daily Press to accompany a visit to the south west, the region most likely to be affected by the government's plan to cut feed-in tariff support for solar farms, Huhne insisted the proposed cuts were necessary to protect incentives for smaller installations and limit upward pressure on energy bills.
"The money for FITs comes from you and [me]: it's a cost which is added to energy bills," he wrote. "When the previous government started FITs, it never predicted or allowed for large-scale solar installations so early on in the scheme. But such interest, especially in the south west, has the real risk of skewing the costs of the whole scheme, which in turn will push up the costs on energy bills and hog the money that was meant for householders."
He said eight solar farms had already been granted planning permission in the south west and an estimated 20 more were in the pipeline, adding that each 5MW solar farm could deny 1,500 homes from claiming feed-in tariffs for solar panels on their roofs.
"Even if only half of these [planned solar farms] go ahead and start claiming FITs, then nearly a fifth of the scheme's projected costs for the next financial year will have already been spent, leaving hundreds of homes, small businesses and communities without," he wrote. "If we let large solar installations continue unabated, then the money will run out and it will run out more quickly."
But solar industry insiders remain furious at the government's decision to review feed-in tariffs for all installations with more than 50kW capacity, including mid-sized rooftop installations that are a fraction of the size of the largest solar farms.
Some critics are now privately accusing the government of exaggerating the scale of the threat presented by solar farms and reneging on a promise to announce a "trigger for early review".
Recently released figures from Ofgem suggest that during the first nine months of the scheme, just £6.2m has been paid out to generators, against the government's projection that spend for the first year of the scheme would be £30m.
BusinessGreen has also obtained documents suggesting the government originally budgeted up to £51m for the first year of the scheme, while a DECC spokeswoman confirmed that even with cuts agreed as part of last year's spending review, the government has budgeted £900m of cumulative spend for the scheme between 2010 and 2014.
The disparity between the £6.2m paid to date under the feed-in tariff and the first-year budget of between £30m and £51m has prompted outrage from some within the industry, who are adamant that there is little evidence of the "solar gold rush" the government has claimed it is trying to counteract.
There is also anger at the decision to renege on commitments made by climate change minister Greg Barker in the House of Commons that the department would announce a "trigger" point at which an early review of the scheme would be enacted ahead of the first scheduled review in 2012.
A DECC spokeswoman said the government had decided to dispense with announcing a trigger point for an early review as it "just wanted to get on with it" and provide the industry with earlier certainty.
She also insisted that government projections suggested a "gold rush" was underway and as such solar farms presented a "threat" to the overall feed-in tariff budget.
"The evidence we have seen shows there are solar farms in the pipeline, and we are aware of more being planned," she said. "If we break the £900m budget, it goes on people's bills and we have a duty of care [to stop that happening]. We have just come out of the recession and we have to be fiscally responsible."

Isra-Mart srl:Falsche EEG-Förderanreize für Biogas-Strom
www.isra-mart.com
Isra-Mart srl news:
Zwischen 2005 und 2010 ist die Maisanbaufläche in Deutschland von 70.000 Hektar auf 600.000 Hektar gewachsen. Grund dafür sind falsche Förderanreize für Strom aus Biomasse im Erneuerbare Energien-Gesetz (EEG). Das EEG belohnt Strom aus Biogas mit umgerechnet jährlich rund 3000 Euro pro Hektar. Das ist fast das Zehnfache dessen, was Bauern sonst pro Hektar durchschnittlich an EU-Förderungen erhalten. Das folgert der World Wide Fund For Nature basierend auf einer aktuellen WWF-Studie.
Die Folge dieser Entwicklung sei, so der WWF, dass Investoren Ackerland im großen Stil pachten oder kaufen und darauf hauptsächlich Energie-Mais anbauen. Während dies für Investoren ein lukratives Geschäft sei, treibe dies jedoch auch die Pachtpreise in die Höhe und verwandele ganze Landstriche in Mais-Monokulturen. „Das Erneuerbare Energien-Gesetz muss in dieser Hinsicht schnell und umfassend geändert werden“, fordert WWF-Agrarreferentin Tanja Dräger de Teran. „Es ist unsinnig, das halbe Land in Maisfelder zu verwandeln. So, wie er heute angebaut wird, vernichtet Mais die Artenvielfalt, belastet die Gewässer und trägt wertvollen Mutterboden ab.“
Der Biogas-Boom lässt die Pachtpreise in vielen Regionen Deutschlands anziehen. In Ostdeutschland haben sich die Pachtpreise für Agrarflächen laut WWF in den vergangenen drei Jahren beinahe verdreifacht. Landwirte haben beim Auslaufen ihrer Pachtverträge häufig das Nachsehen, weil die Anlagenbetreiber höhere Preise pro Hektar bieten. Rund 60 Prozent der deutschen Landwirte pachten Land.
Nach WWF-Angaben ist die Zahl der Biogasanlagen in Deutschland von etwa 2000 im Jahr 2005 auf heute 6000 gestiegen. Während die Erzeugung von Bioethanol aus Mais Nachhaltigkeitskriterien erfüllen muss, gelten diese für die Produktion von Biogas aus Mais nicht. „Das ist vollkommen unlogisch und muss sich umgehend ändern“, so die WWF-Expertin.
„Die derzeitige Situation zeigt, dass Bioenergie nicht per se umweltfreundlich oder nachhaltig ist. Es kommt sehr darauf an, woher die Rohstoffe stammen und wie sie angebaut werden“, so Tanja Dräger. Die Bundesregierung müsse nun schnell das EEG verbessern. Die geltenden Nachhaltigkeitskriterien für Biokraftstoffe müssten auch für Energiepflanzen gelten, die zum Betrieb von Biogasanlagen angebaut werden.

Isra-Mart srl:Verbraucherzentrale berät zu Schimmel und Feuchtigkeit in der Wohnung
www.isra-mart.com
Isra-Mart srl news:
Der aktuelle Winter erweist sich als besonders hartnäckig. Wegen der langandauernden Kälte sind alle Bauteile eines Hauses sowie unbeheizte Räume ausgekühlt. Durch Kondenswasser und unregelmäßiges Lüften kann Schimmel entstehen. Architekten und Ingenieure der Energieberatung der Verbraucherzentrale Thüringen beraten zur Vorbeugung und Beseitigung von Schimmel.
Durch die normale Nutzung der Wohnung mit Duschen, Kochen, Wäschetrocknen usw. wird die Luft mit Wasser angereichert. Je geringer die Raumtemperatur, desto geringer ist dabei die Wasseraufnahmefähigkeit. Kühlt sich die Luft an kalten Fenstern oder Mauerstellen ab, schlägt sich überschüssige Feuchtigkeit als Kondenswasser nieder. An den Außenwänden sieht man dieses Kondenswasser erst einmal nicht so deutlich. Wird jedoch durch unzureichendes Lüften oder einen behinderten Luftaustausch die Feuchtigkeit nicht abgeführt, so bilden sich an kalten Stellen dauerfeuchte Stellen, an denen sich schnell Schimmelpilze ansiedeln können. Besonders gefährdet sind deshalb Bereiche, die deutlich kälter sind als ihre Umgebung, also Ecken an der Außenwand oder kühle Räume wie das Schlafzimmer.
Schimmelpilz zeigt sich mit einer meist grünen oder schwarz-grauen Verfärbung der befallenen Flächen. Allerdings können diese Stellen auch versteckt sein, z.B. unter einer Matratze oder hinter einem Schrank. Bei flächigem Befall macht sich ein muffiger Geruch bemerkbar. „Liegt ein Verdacht auf Schimmelpilzbefall vor, sollte man neben dessen Beseitigung auch der Ursache auf den Grund gehen, da ansonsten früher oder später mit einem erneuten Auftreten zu rechnen ist“, sagt Dr. Wiggo Weber, Energieberater der Verbraucherzentrale.

Isra-Mart srl:Fachkräftemangel behindert energetische Gebäudesanierung
www.isra-mart.com
Isra-Mart srl news:
Die energetische Sanierung von Gebäuden bietet große Chancen für Klimaschutz und Beschäftigung. Bis zum Jahr 2030 lassen sich im Gebäudesektor nahezu 30 Prozent der Treibhausgasemissionen einsparen. Wie eine neue Studie für das UBA zeigt, mangelt es jedoch zunehmend an einschlägig qualifizierten Fachkräften, um Sanierungen optimal zu planen und umzusetzen.
Der Deutscher Industrie- und Handelskammertag (DIHK) e.V. bestätigt diesen Trend: Bei der Qualifizierung des Fachkräftenachwuchses in Europa gibt es Probleme: Jeder siebte 18-bis 24-Jährige in der Europäischen Union hat entweder keinen Schulabschluss oder nur einen Abschluss der Sekundarstufe I ohne weiterführende Schul- oder Berufsausbildung. Die auf EU-Ebene so definierte Abbrecherquote liegt damit im Schnitt in der EU bei über 14 %; in Deutschland bei gut 11 %.
Aus diesem Grund werden derzeit nur etwa ein Drittel der wirtschaftlich lohnenden Energiesparpotenziale im Gebäudebestand ausgeschöpft. Die Baubranche hat dies erkannt: Rund 80 Prozent der Handwerksbetriebe und rund 90 Prozent der Ingenieurbüros sehen ihren künftigen Arbeitsschwerpunkt im Bausektor bei der Altbausanierung. Überdies sichert eine qualifizierte Ausbildung die Qualität der energetischen Gebäudesanierung: Falls wirtschaftlich vorteilhafte Energieeinsparmaßnahmen nicht oder nicht sachgerecht ausgeführt werden, schadet das erstens dem Klimaschutz. Zweitens entstehen unnötig hohe Kosten für die Gebäudeeigentümer und Mieterinnen und Mieter; vor allem bei steigenden Energiepreisen für fossile Rohstoffe.

Isra-Mart srl:IMGB Doosan. Cum sa eficientizezi un energofag si sa scazi consumul cu 20%
www.isra-mart.com
Isra-Mart srl news:
In cinci ani, unul dintre cei mai mari energofagi ai Romaniei - compania IMGB Doosan - a redus consumul de gaze si electricitate cu 20%, in ciuda cresterii productiei. O data cu consumul a scazut si costul de productie, iar asta gratie unei strategii de investitii majore in eficientizarea energetica, insumata la cateva zeci de milioane de euro.
Printre masurile de eficientizare s-au numarat achizitionarea unor echipamente noi, reabilitarea altora si imbunatatirea semnificativa a managementului energetic.
Energia - un sfert din costurile de productie
In 1964, in Capitala se infiinta IMGB, cea mai mare companie din istoria sistemului socialist romanesc. Pana la Revolutie, in fabrica intinsa pe aproximativ doua milioane de metri patrati lucrau peste 16.500 de angajati. Intre timp, compania a fost privatizata, intr-o prima etapa cu firma norvegiana Kvaerner, iar mai apoi a fost cumparata de sud-coreenii de la Doosan. Acum compania se intinde pe o suprafata de peste 500.000 de metri patrati si are circa 700 de angajati.
Doosan IMGB este cel mai mare producator de piese turnate si forjate din Romania. Printre activitatile sale se numara productia de otel lichid, procesele de formare-turnare, forjare, tratament termic si finisare. Cifra de afaceri a Doosan IMGB a fost in jurul a 100 de milioane de euro in 2010. Majoritatea productiei merge catre export, in Coreea de Sud, Rusia, Germania si Statele Unite.
Odata cu venirea conducerii sud-coreene, in IMGB au inceput schimbarile: treptat, productia s-a modernizat, cu accent pe eficientizarea proceselor, si au aparut si primele investitii serioase in reducerea consumului de energie.
Anul trecut, la IMGB s-au produs peste 80.000 de tone de otel lichid. Pentru 2011, Costel Cirstea, managerul energetic al Doosan IMGB estimeaza o productie de otel cel putin similara celei din anul 2010. Procesele de productie din acest domeniu - metalurgie - sunt procese energofage. De la turnarea otelului in otelaria electrica, forjare, tratamente termice, prelucrari mecanice, incercari si teste si pana la pregatirea pentru livrare, cantitatile de energie electrica si gaze consumate nu sunt deloc de neglijat, costurile cu energia ajungand la circa 25 % din cheltuielile pe produs.
Sistem on-line de gestiune a energiei
“Suntem la circa 115-125 % din consumul pe care il au fabricile din Europa de Vest in procesul de productie, insa promovam solutii pentru a reduce aceste cifre”, a declarat d-l Costel Cirstea.
Pentru a imbunatati eficienta energetica in intregul proces, Doosan IMGB a investit intr-un sistem online de gestiune a energiei. Acesta monitorizeaza consumul de gaze si energie electrica atat la interfata cu furnizorii, cat si in diferitele zone de consum si notifica atunci cand apar neincadrari semnificative.
“Fiecare manager este responsabil de consumul sectiei pe care o conduce. Atunci cand se depasesc parametrii de consum, se ia legatura cu managerul sectiei respective pentru a se lua cele mai eficiente masuri, in timp cat mai scurt. In fiecare zi avem rapoarte in privinta consumului din ziua anterioara”, a declarat d-l Costel Cirstea.
Toate cuptoarele vor fi reabilitate
Investitii masive s-au facut si in reabilitarea cuptoarelor de forja si tratamente termice, solutiile de modernizare avand in vedere inlocuirea izolatiei din vata minerala cu izolatie din fibra ceramica si automatizarea proceselor de ardere. Programul de reabilitare are in vedere toate aceste cuptoare de forja si tratamente termice, majoritatea acestora fiind reabilitate, altele sunt in curs de reabilitare, altele asteapta.
Trei dintre acestea au fost renovate cu un credit acordat de la Banca Europeana pentru Reconstructie si Dezvoltare, prin programul Energy Efficiency Finance Facility. Investitia a fost de un milion de euro si a condus la reducerea consumului de gaze naturale pe cuptor de la 500-600 metri cubi de gaze pe ora la 400-450 de metri cubi pe ora.
Tot cu ajutorul BERD, cu o investitie de 1,5 milioane de euro, a fost construita o centrala de aburi noua si performanta, principalele echipamente fiind furnizate de firma Loos din Germania. In raport cu vechea centrala, eficienta energetica in producerea aburului a crescut, in noua centrala, cu circa 30%, a explicat d-l Costel Cirstea.
Centrala functioneaza de un an, fiind deja masurat impactul ecologic cu ajutorul parametrilor de functionare care sunt monitorizati continuu.
“Impactul ecologic al centralei de abur a fost redus considerabil odata cu cresterea eficientei proceselor tehnologice si reducerea emisiilor. Acum emisiile sunt sub normele admise, iar acest lucru a fost posibil cu ajutorul arzatoarelor de ultima generatie”, a explicat d-l Costel Cirstea.
Pe langa cele trei cuptoare reabilitate cu finantare BERD, obiectivul IMGB este sa reabiliteze toate cuptoarele. In total, in IMGB exista peste 30 de cuptoare, dintre care circa 50 % sunt reabilitate. Investitiile sunt directionate in principal spre cresterea eficientei echipamentelor, cuptoarelor, presei si in zona prelucrarilor (toate masinile si echipamentele au fost reabilitate).
Consum de gaze cu 20% mai mic
“Reabilitarea a avut scopul de a aduce masinile intr-un domeniu de precizie si mai ridicat si de extindere a duratei de viata dintre doua interventii”, a mentionat d-l Costel Cirstea. Estimativ, in zona de tratare si forjare, modernizarile au dus la o reducere cu 20% a consumului de gaze naturale. In zona de productie a otelului, consumul de energie electrica a scazut de la 750 kWh pana la cel mult 580-600 kWh pe tona de otel lichid produs.
“Simpla prezenta a sistemului de gestiune online si a publicarii datelor a facut ca implicarea personalului de decizie sa creasca si energia sa fie evaluata ca unul dintre vectorii foarte importanti in activitatea Doosan IMGB”, a mai adaugat managerul departamentului de Energie si Utilitati din cadrul Doosan IMGB.
Investitiile in protectia mediului au inceput in anul 2006, iar Programul de conformare este programat sa se inchida in 2014. Printre acestea se numara si investitii in partea de filtrare a emisiilor: compania are o instalatie de colectare centralizata a emisiilor din procesul de elaborare a otelului, care functioneaza de 2 ani si al carei termen de finalizare era 2014. Investitia in aceasta instalatie a fost de circa 10 milioane de dolari.
Astfel, aproape toate proiectele din Autorizatia Integrata de Mediu sunt finalizate. Au mai ramas nefinalizate pana acum sub 5 % din actiuni, unele fiind in derulare, potrivit reprezentantului IMGB.

In cinci ani, unul dintre cei mai mari energofagi ai Romaniei - compania IMGB Doosan - a redus consumul de gaze si electricitate cu 20%, in ciuda cresterii productiei. O data cu consumul a scazut si costul de productie, iar asta gratie unei strategii de investitii majore in eficientizarea energetica, insumata la cateva zeci de milioane de euro.
Printre masurile de eficientizare s-au numarat achizitionarea unor echipamente noi, reabilitarea altora si imbunatatirea semnificativa a managementului energetic.
Energia - un sfert din costurile de productie
In 1964, in Capitala se infiinta IMGB, cea mai mare companie din istoria sistemului socialist romanesc. Pana la Revolutie, in fabrica intinsa pe aproximativ doua milioane de metri patrati lucrau peste 16.500 de angajati. Intre timp, compania a fost privatizata, intr-o prima etapa cu firma norvegiana Kvaerner, iar mai apoi a fost cumparata de sud-coreenii de la Doosan. Acum compania se intinde pe o suprafata de peste 500.000 de metri patrati si are circa 700 de angajati.
Doosan IMGB este cel mai mare producator de piese turnate si forjate din Romania. Printre activitatile sale se numara productia de otel lichid, procesele de formare-turnare, forjare, tratament termic si finisare. Cifra de afaceri a Doosan IMGB a fost in jurul a 100 de milioane de euro in 2010. Majoritatea productiei merge catre export, in Coreea de Sud, Rusia, Germania si Statele Unite.
Odata cu venirea conducerii sud-coreene, in IMGB au inceput schimbarile: treptat, productia s-a modernizat, cu accent pe eficientizarea proceselor, si au aparut si primele investitii serioase in reducerea consumului de energie.
Anul trecut, la IMGB s-au produs peste 80.000 de tone de otel lichid. Pentru 2011, Costel Cirstea, managerul energetic al Doosan IMGB estimeaza o productie de otel cel putin similara celei din anul 2010. Procesele de productie din acest domeniu - metalurgie - sunt procese energofage. De la turnarea otelului in otelaria electrica, forjare, tratamente termice, prelucrari mecanice, incercari si teste si pana la pregatirea pentru livrare, cantitatile de energie electrica si gaze consumate nu sunt deloc de neglijat, costurile cu energia ajungand la circa 25 % din cheltuielile pe produs.
Sistem on-line de gestiune a energiei
“Suntem la circa 115-125 % din consumul pe care il au fabricile din Europa de Vest in procesul de productie, insa promovam solutii pentru a reduce aceste cifre”, a declarat d-l Costel Cirstea.
Pentru a imbunatati eficienta energetica in intregul proces, Doosan IMGB a investit intr-un sistem online de gestiune a energiei. Acesta monitorizeaza consumul de gaze si energie electrica atat la interfata cu furnizorii, cat si in diferitele zone de consum si notifica atunci cand apar neincadrari semnificative.
“Fiecare manager este responsabil de consumul sectiei pe care o conduce. Atunci cand se depasesc parametrii de consum, se ia legatura cu managerul sectiei respective pentru a se lua cele mai eficiente masuri, in timp cat mai scurt. In fiecare zi avem rapoarte in privinta consumului din ziua anterioara”, a declarat d-l Costel Cirstea.
Toate cuptoarele vor fi reabilitate
Investitii masive s-au facut si in reabilitarea cuptoarelor de forja si tratamente termice, solutiile de modernizare avand in vedere inlocuirea izolatiei din vata minerala cu izolatie din fibra ceramica si automatizarea proceselor de ardere. Programul de reabilitare are in vedere toate aceste cuptoare de forja si tratamente termice, majoritatea acestora fiind reabilitate, altele sunt in curs de reabilitare, altele asteapta.
Trei dintre acestea au fost renovate cu un credit acordat de la Banca Europeana pentru Reconstructie si Dezvoltare, prin programul Energy Efficiency Finance Facility. Investitia a fost de un milion de euro si a condus la reducerea consumului de gaze naturale pe cuptor de la 500-600 metri cubi de gaze pe ora la 400-450 de metri cubi pe ora.
Tot cu ajutorul BERD, cu o investitie de 1,5 milioane de euro, a fost construita o centrala de aburi noua si performanta, principalele echipamente fiind furnizate de firma Loos din Germania. In raport cu vechea centrala, eficienta energetica in producerea aburului a crescut, in noua centrala, cu circa 30%, a explicat d-l Costel Cirstea.
Centrala functioneaza de un an, fiind deja masurat impactul ecologic cu ajutorul parametrilor de functionare care sunt monitorizati continuu.
“Impactul ecologic al centralei de abur a fost redus considerabil odata cu cresterea eficientei proceselor tehnologice si reducerea emisiilor. Acum emisiile sunt sub normele admise, iar acest lucru a fost posibil cu ajutorul arzatoarelor de ultima generatie”, a explicat d-l Costel Cirstea.
Pe langa cele trei cuptoare reabilitate cu finantare BERD, obiectivul IMGB este sa reabiliteze toate cuptoarele. In total, in IMGB exista peste 30 de cuptoare, dintre care circa 50 % sunt reabilitate. Investitiile sunt directionate in principal spre cresterea eficientei echipamentelor, cuptoarelor, presei si in zona prelucrarilor (toate masinile si echipamentele au fost reabilitate).
Consum de gaze cu 20% mai mic
“Reabilitarea a avut scopul de a aduce masinile intr-un domeniu de precizie si mai ridicat si de extindere a duratei de viata dintre doua interventii”, a mentionat d-l Costel Cirstea. Estimativ, in zona de tratare si forjare, modernizarile au dus la o reducere cu 20% a consumului de gaze naturale. In zona de productie a otelului, consumul de energie electrica a scazut de la 750 kWh pana la cel mult 580-600 kWh pe tona de otel lichid produs.
“Simpla prezenta a sistemului de gestiune online si a publicarii datelor a facut ca implicarea personalului de decizie sa creasca si energia sa fie evaluata ca unul dintre vectorii foarte importanti in activitatea Doosan IMGB”, a mai adaugat managerul departamentului de Energie si Utilitati din cadrul Doosan IMGB.
