就中间储仓式热风送粉煤粉炉三次风带粉量大对锅炉低负荷燃烧所产生的负面影响 (包括燃烧的稳定性、煤粉着火性、火检强度等 ) ,从安全性和经济性两方面进行了分析 ,提出了锅炉在低负荷阶段制粉系统合理的运行方式 ,即在锅炉低负荷阶段 ,保留两套制粉系统较宜 ,通过调节给煤量维持磨煤机出口温度以减少系统漏风 ,降低单位煤粉能耗等
In view of the negative influence (including the stability of combustion, the ignition of pulverized coal, the intensity of fire detection, etc.) on the low-load combustion of the boiler caused by the tertiary air volume with large amount of powder in the middle storage bunker hot-blast pulverized coal fired boiler, the safety and economy This paper analyzes the reasonable operation of the pulverizing system of the boiler at low load stage, that is, it is better to keep two pulverizing systems in the stage of low load of the boiler, and maintain the outlet temperature of the pulverizer by adjusting the amount of coal supplied Reduce system air leakage and reduce energy consumption per unit of coal
