奎屯热电厂 4号炉投入运行后 ,由于正压喷火严重 ,严重影响设备的正常运行。锅炉正压喷火的原因是部分设备安装质量较差、锅炉设计及运行调整不当、燃料粒度及湿度不符合要求。消除正压喷火的方法及改造措施如下 :处理炉墙的泄漏、处理烟囱内隔烟墙、处理引风机引风量的不足、处理煤的粒度和湿度、调节燃烧的配风、定期清理烟风道内及炉内的积灰
Kuitun Thermal Power Plant No. 4 furnace put into operation, due to serious pressure spit fire, seriously affecting the normal operation of equipment. The reason for the positive pressure of the boiler is that the quality of some equipment is poor, the boiler design and operation are not properly adjusted, and the fuel particle size and humidity do not meet the requirements. The methods and measures to eliminate positive pressure flame are as follows: dealing with the leakage of the furnace wall, dealing with the smoke walls inside the chimney, dealing with the insufficiency of the induced draft of the induced draft fan, treating the particle size and humidity of the coal, regulating the combustion air distribution, Road and furnace fouling
