摘要:在某电厂300MW燃煤机组进行提高磨煤机出口粉温试验研究,分析提高磨煤机出口粉温后对锅炉燃烧、机组经济性和安全性的影响。试验结果表明,磨煤机出口粉温由82.0℃提升至90.0℃运行,锅炉运行参数没有较大异常变化,锅炉排烟温度下降约4.0℃,影响煤耗下降约0.89g/(kW·h),经济效益显著。提高磨煤机出口粉温试验,不需要花费较大成本,便可创造出额外的经济效益,达到节能降耗的目的。

Abstract:After the experimental study of to increase pulverizor outlet powder temperature on a power plant’s 300MW coal fired unit.This paper analyzed the effect of increasing pulverizer outlet powder temperature to boiler combustion,unit economy and safety.The experiment result indicated that to increase the powder temperature from 82℃ to 90℃,the operating parameter was not changed significantly, but the exhaust temperature was lower by four degrees celsius,coal cost lower by 0.89g/(kW·h).Which is remarkable on economic benefits.To increase pulverizer outlet powder temperature is low cost but would create extra economic benefits and saving energy.
Key words: Keywords:coal fired unit;outlet powder temperature, system margin;exhaust gas temperature, energy saving
