Abstract:The problems in 300 MW boiler have seriously impacted the efficiency since the operation of No. 3 boiler in Huadian Qingdao Power Generation Co., Ltd. , including the exist of fly ash, high carbon content in the slag, large air leakage in air preheater, over high-speed of the primary air, blockage in the coarse coal powder classifier, inferior coal fineness, unstable combustion at low load, and serious blower pinch etc. Almost all the problems were solved by the optimization test, operation adjustment test and the reconstruction for certain equipment, thus the boiler efficiency has been significantly increased.
Keywords:optimization  operation adjustment  boiler efficiency
