2007/04/18 阿爾斯通Power Nederland BV與Nuon Power Generation BV簽署了一份合同，升級Merwedekanaal 12發(fā)電站的GT13E渦輪和壓氣機。該合同是正在實行的工廠壽命延長程序的一部分。 GT13E渦輪升級到E1M 1到3排的渦輪葉片將用阿爾斯通成熟的“M”技術(shù)葉片替代，該葉片具有先進(jìn)的螺旋槳設(shè)計，冷卻理念，合金材料和外殼。 為了滿足個別市場的要求，這種升級使客戶可以在任何時候利用同一個硬件包改變“能量”和“壽命”運行模式間的引擎模式。 效率提高 當(dāng)在能量模式下運行時，升級渦輪和壓氣機共同為客戶提供約8％的額外燃?xì)鉁u輪功率輸出，并且效率提高了至少1.5％（增加的），在壽命擴展“XL”模式下，將會得到更合適的功率，提高效率，同時C檢查間的時間間隔從24,000到32,000等效運行小時數(shù)（EOH）――在基本負(fù)荷連續(xù)運行時，從間隔三年提高到四年。 元件壽命延長意味著要求更少的部件替換或修復(fù)工作，并且增加服務(wù)時間間隔，這樣就降低了渦輪整體維修成本，停機檢修時間的減少將意味著可靠性的增強，生產(chǎn)能力的提高和收入的增加。 升級壓氣機進(jìn)一步提高輸出和效率 安裝升級壓氣機將繼續(xù)提高工廠的產(chǎn)出，這種壓氣機采用高效可控擴散葉型設(shè)計（根據(jù)成熟的 GT24/GT26，GT11N2和GT11NMC技術(shù)設(shè)計），并在全球成功應(yīng)用于阿爾斯通燃?xì)鉁u輪。每個壓氣機級都運用空氣動力學(xué)優(yōu)化以最大的提高效率和增壓比。 升級渦輪和壓氣機將計劃在2008年四月下次渦輪C檢查時實施。 original text： [COLOR=#708090]Turbine and compressor upgrade for the Nuon Merwedekanaal 12 Power Station, Netherlands Alstom Power Nederland BV has signed a contract with Nuon Power Generation BV to upgrade a GT13E turbine and compressor at the Merwedekanaal 12 power station. This contract is part of an ongoing lifetime extension programme at the plant. GT13E turbine upgraded to E1 M The turbine blades and vanes of rows 1 to 3 will be replaced with Alstom‘s proven "M" technology blading featuring advanced airfoil designs, cooling concepts, alloys, and coatings. To fulfil individual market requirements, this upgrade allows customers at any time, with the same hardware package, to change the mode of the engine between "Power" and "Lifetime" operating modes. Improved efficiency When operated in the "Power" mode the turbine and compressor upgrades are together expected to deliver the customer approximately 8% extra gas turbine power output, and an efficiency improvement of at least 1.5% （multiplicative）. In the lifetime extending "XL" mode more modest power and efficiency increases will be achieved, while the interval between C-inspections is lengthened from 24,000 to 32,000 Equivalent Operating Hours （EOH） - from 3 to every 4 years when continuously operated at baseload. Extended component lifetime means less parts replacement or reconditioning work will be required, and service intervals can be increased, thus reducing the overall maintenance cost of the turbine. Reduced maintenance downtime will mean increased availability resulting in increased production capacity and revenues. Compressor upgrade further boosts output and efficiency Together with the turbine upgrade, an improved compressor will be installed which will also contribute to increasing the plant‘s output. This compressor utilizes the highly efficient Controlled Diffusion Airfoil design adapted from proven GT24/GT26, GT11N2 and GT11NMC technology and used successfully in a large number of Alstom gas turbines worldwide. Each compressor stage is aerodynamically optimised to maximise efficiency and pressure ratio. The upgrades will be implemented during the next turbine C-inspection, scheduled for April 2008.[/COLOR]
