【摘要】 针对胜利发电厂 670t/h贫煤锅炉燃用高挥发分煤种烧坏喷燃器和一次风粉管的问题 ,提出了降低一次风温的解决办法 :一是采用迅速深度降低机组负荷的运行方式 ;二是对燃烧系统进行改造 ,设法将冷风掺入一次风中 ,降低一次风温 ,以实现在少降机组负荷的情况下锅炉喷燃器和一次风粉管安全运行更多还原

【Abstract】 By using lean coal the boiler of the type 670t/h in Shengli Power Plant using high volatile coal burning out the crater and primary air inlet, the way to reduce the temperature of primary air is brought forward in the text: one is reducing the load of sets fleetly and deeply, the other is rebuilding the combustion system by to reduce the temperature, mixing cold blast with primary air, to assure a safe operation in a slight reducing load situation.更多还原
