摘要:

以300MW机组为例,对暖风器与低压省煤器联合系统的两种典型布置方案的节能量进行了对比分析。通过理论计算,得出热耗率验收工况下两种布置方案的供电煤耗差异为0.89g/(kW·h),可为发电厂进行此类改造提供参考。

Abstract:

Taking a 300MW unit as an example, compared the classic layouts and energysaving schemes of two combined systems with air heater and lowpressure economizer. Through theoretical analysis, the differences of coal consumption between 2 schemes is 0.89g/(kW·h) under heat consumption acceptance condition ,which can provide a reference for the power plant which is willing to carry out a similar transformation.
