摘　　要：以某660MW超临界燃机组为例,通过开展深度调峰试验研究,评估锅炉、汽机低负荷运行安全性,结合环保指标,得出该机组能够满足浙江省发改委关于燃煤机组深度调峰机组最小出力应达到40%额定负荷的要求。通过开展经济性评估,得出机组负荷低于50%负荷运行时,供电煤耗将大幅度上升,电厂应以此为依据积极争取调峰电价补偿。A 660MW supercritical combustion unit has been taken as an example to evaluate the safety of low-load operation of boiler and steam turbine by carrying out in-depth peak regulation test,combined with environmental protection indexes,the unit can meet the requirements of the minimum output should reach 40%of the rated load issued by Zhejiang Provincial Development and Reform Commission.Through economic evaluation,it is concluded that when the unit load is less than 50%,the power supply coal consumption will be raised significantly,and the power plant should actively strive for peak-regulation price compensation on this basis.
