起停炉水泵造成汽包水位保护动作原因分析及改进措施

Huaneng fuzhou power plant unit # 1 boot process the influence of steam drum water level of boiler water pump for analyses

机组运行过程中,当锅炉中炉水处于不同的压力和温度,炉水泵起停时对汽包水位的影响是不同的,锅炉压力刚刚建立后启动炉水泵情况比较复杂,会发生汽包水位上升的情况。

In the process of unit operation,when the boiler water in different pressure and temperature in the furnace,the boiler water pump Starting and stopping is different to steam drum water level,the effects of boiler pressure pump on furnace has just set up after the situation is more complex,the steam drum water level rise will happen.
