摘要
凝结水泵电耗高一直是某公司1000 MW机组的难题,通过解决凝结水泵振动超标问题,使凝结水泵由工频转为变频运行,大幅降低凝结水泵电耗率,并对凝结水系统运行方式进行优化,采取降低节流损失、深度变频运行、双泵并列运行等手段,进一步挖掘了变频器的节能潜力,最终将凝结水泵电耗率降低了0.15%,设计了机组启动过程中凝结水回收方案,使机组经济性大幅提升,值得在行业内进行推广。
High power consumption of the condensate pump is always a difficult problem in 1 000 MW unit of a company,by solving the problem of excessive vibration,the condensate pump can works in frequency-conversion mode,greatly reduced the power consumption rate of the condensate pump,the operation mode of condensate water system is optimized by means of reducing throttling loss,reducing the frequency conversion operation and double pump running in parallel,because of the further dig of the energy saving potential of frequency converter,the condensate pump power consumption rate was reduced by 0. 15% eventually,the condensate recovery plan in the startup process of the unit is designed,the unit economical was greatly enhanced,these experiences are worthy of promotion in the industry.
