摘　　要：某新建机组在稳压吹管过程中,利用吹扫蒸汽通过高压加热器来加热给水,提高给水温度,从而降低吹管期间的能耗。同时使主、再蒸汽温度稳定可控,减少了主、再热器减温水的用量,降低了再热器及临时管路超温的风险。A new unit in voltage stability in the process of torch, using purge steam through the high pressure heater to heat water, improve the feed temperature, thereby reducing the energy consumption during the torch. Lord, stable and steam temperature controlled at the same time, reduce the reheater decrease the dosage of the warm water, reduce the risk of reheater overtemperature and temporary pipeline.

关 键 词：稳压吹管 给水温度 高压加热器
