摘要
Abstract
It carries out the test of 20%rated load deep peak shaving in the No.4 350 MW unit of a power generation company.During the load reduction process,the parameters of 105 MW,90 MW,80 MW and 70 MW are selected for testing and analysis.Research finds that under 20%rated load,two B/C coal mills operate,with a minimum power generation load of 72 MW,a minimum boiler evaporation capacity of 230 t/h,a main steam pressure of 11.28 MPa,a main steam temperature of 490℃,a reheat steam temperature of 440℃,and a flue gas temperature of 290℃at the denitration inlet.Under various operating conditions,the flame detection signal and furnace negative pressure fluctuate normally.The boiler combustion is stable,and the operating parameters of the steam turbine are normal.The environmental indicators are within the qualified range,and the auxiliary equipment operates smoothly.It provides reference for the subsequent development of reasonable equipment transformation and logic optimization scheme.关键词
