阿爾斯通已經(jīng)與EnBW Kraftwerke AG簽訂了約2千萬歐元的合同，為位于德國的燃煤發(fā)電廠Heilbronn Block 7重新供以動力。此合同是阿爾斯通Turbine Retrofit Mannheim group （TSR）繼2007年8月簽訂的為蒸汽渦輪機HP-IP-LP更新的價值二千三百萬歐元合同后的又一大合同。 Alstom Boiler Retrofit Stuttgart （EBR）新簽訂的合同是由TSR和EBR聯(lián)合開發(fā)的一體化鍋爐渦輪解決方案所帶來的成果。在斯圖加特的鍋爐改進集團與TSR一起協(xié)作致力于開發(fā)和確定使性能和輸出都能最大化的解決方案。與EnBW Kraftwerke AG合作的重新供以動力的工程將提高現(xiàn)有7號機組的輸出能力。除此之外，Heilbronn Block 7電廠塔式鍋爐的效率也將因應(yīng)用TSR和EBR制定的解決方案而得到提高。 鍋爐從根本上的改造，包括替換現(xiàn)存的4個球磨機，更換成能于動態(tài)分類器相適配的高性能磨機。這些新設(shè)備不僅能改善工廠的輸出產(chǎn)量還允許多出的煤能在鍋爐中燃燒。更多的關(guān)鍵性改變將被帶到電廠的其它部分：如輸煤管和其它用于連續(xù)提供足夠數(shù)量更新球磨機的升降壓機風(fēng)扇。 此外，兩個空氣預(yù)熱器提供用于改善鍋爐效率和蒸汽渦輪設(shè)備改進時使用，同時降低二氧化碳的排放量。 此工程預(yù)定于2009年11月完工。 [FONT=times] original text [/FONT] [font=times] ALSTOM WINS BOILER REPOWERING CONTRACT FOR COAL-FIRED POWER PLANT IN GERMANY [/font] [font=times][Color=#708090]Alstom wins boiler repowering contract for coal-fired power plant in Germany Alstom has signed a contract worth approximately 20 million euros with EnBW Kraftwerke AG for the repowering of the Heilbronn Block 7, a coal-fired power plant in Germany. This award follows on from a previous contract worth 23 million euros for the HP-IP-LP retrofit of the steam turbine at the same site which was signed with Alstom Turbine Retrofit Mannheim group （TSR） in August 2007. This new contract for Alstom Boiler Retrofit Stuttgart （EBR） is the result of an integrated boiler-turbine solution developed by TSR and EBR. The Boiler Retrofit group in Stuttgart worked closely together with TSR and EnBW Kraftwerke AG in order to develop and define the optimised overall solution for maximum performance and output. The repowering Project with EnBW Kraftwerke AG will increase the output of the existing Unit 7. In addition to this, the efficiency of the existing once-through, tower-type boiler power plant, Heilbronn Block 7 will increase due to the modifications made by TSR and EBR. The boiler modifications essentially consist of replacing the existing 4 bowl mills with higher performance mills which are fitted with dynamic classifiers. These new mills not only improve the mill’s output but also allow an extended range of coals to be fired within the boiler. Further key modifications will be brought to parts of the pulverised coal ducts and an additional booster fan which collectively provides a sufficient amount of hot air for the upgraded coal mills will be implemented. Furthermore, two new steam air heaters will be provided to further improve the boiler’s efficiency, and coupled with the modifications to the steam turbine equipment, will reduce CO2 emissions from the Heilbronn Block 7 power plant. The project is scheduled for completion in November 2009.[/color][/font]
