| Abstract: | This paper introduces the retrofit of the four corner tangential low NOx 480 t/h combustor of #10 boiler in Yancheng Power Generation Company. After transformation, all the key parameters including the content of NOx , carbon content in the fly ash, the temperature of the exhaust gas and the boiler efficiency can meet the design requirements. For the significant steam temperature fluctuations encountered during initial stages after putting the unit into operation, optimization adjustments were implemented and satisfactory effects were finally obtained. This work can provide valuable reference for similar power units performing combustor retrofit and operation optimization. |
