摘要
针对某300 MW空冷机组进行试验研究,在不同的负荷和环境温度下,分析了风机投运方式变化引起厂用电率和背压变化,分析了风机运行频率同机组运行经济性的关系。试验表明,在一定的背压和风机运行频率下可以通过降低风机的运行频率来提高机组经济性。并总结出了调整的范围区域,可以很直观的指导运行人员的操作。
The experimental research for 300 MW air cooling units under different load and different ambient temperature,analysis of changes in the fan and put into operation the way,this cause the power consumption rate and back pressure changes,fan operating frequency relationship with the economy of units operation. The tests showed that the certain back pressure and frequency of the fan operation by reducing the operating frequency of the fan to increase the units economy. And summed up the adjustment range of areas,it can be very intuitive guide the operation for the operating personnel.
