225MW机组双背压改造供热分析

Analysis of Heat Supply by Double Back Pressure of 225MW Unit

通过对225MW三缸三排汽机组低真空循环水单缸相的供热首次改造尝试,在国内中大型汽轮机发电机组的节能改造中,迈出了关键的一步。运用本次改造成功经验,大大降低了225MW机组发电煤耗,为满足节能减排要求奠定了基础。

Based on 225MW three cylinder exhaust steam unit low vacuum circulating water single cylinder exhaust steam heat-ing reform attempts, for the first time in domestic energy-saving reconstruction of large steam turbine generator set, took a key step. Using the successful experience in the, greatly reduces the 225 mw power generation coal consumption, which laid a foundation to meet the requirements of energy conservation and emissions reduction.
