摘要:

为降低火电机组停机备用期间的能耗,在分析停机备用期间主要能耗的基础上,将氢压降至0.150MPa并停运定冷水系统、氢气干燥器、闭式水泵和密封油泵,氢气纯度及露点仍符合要求,每年可节约电费及设备维护费约80万元,节能降耗效果显著。

Abstract:

To reduce the energy consumption while thermal power unit reserving, the main energy consumption in reserving period was analysed. After set the hydrogen pressure to 0.150MPa and stopped cooling water system, hydrogen dryer, close type pump and oilseal pump, the hydrogen purity and dew point satisfied the requirement and would save 800000 Yuan on energy and maintenance.
