摘要
介绍了盐城发电有限公司10号锅炉480 t/h四角切圆低氮燃烧器改造情况,改造后锅炉氮氧化物、飞灰含碳量、排烟温度、锅炉效率等指标都达到了设计要求,投产初期负荷变化过程中汽温波动幅度较大,通过运行优化调整,汽温变化满足负荷变化要求,对同类型机组低氮燃烧器改造与运行优化调整具有较好的参考价值。
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.
