摘要
随着海拔高度的增加,大气压力明显降低,较低的大气压力将对煤粉颗粒在炉内的燃烧造成一定的影响。文章从燃烧理论及传热学原理出发,着重分析了海拔高度对煤粉炉内燃烧和锅炉排烟温度的影响。
When orthometric elevation increase,the atmospheric pressure will decrease,the decreasing atmospheric pres-sure will affect the boiler combustion.The article will use the theory of combustion and heat transfer to analyze the affection of the orthometric elevation to the boiler compustion and flue gas temperature.
