Optimization Reformation of Boiler Burner with Ultra-Low Emission at Low Load
The structural features and main characteristics of a new low load burners(low NOx double sorting burner)were introduced.Its optimization transformation plan and performance test results of it were analyzed in the flexibility retrofit of 2×600 MW coal-fired boilers of a power station.The results show that the burner can effectively solve the problems of burning out of burner,high temperature corrosion of water wall and low adaptability to coal change under low loads.After transformation,the stable combustion without oil can be realized under the load of 20％ boiler maximum continuous rating,the boiler efficiency can be increased to 93.37％ ,and NOx emission can be effectively suppressed with the emission mass concentration of 35.9 mg/m3.
