摘要
排烟热损失是锅炉最大的一项热损失,对锅炉效率影响很大。现在300MW循环流化床(CFB)锅炉已经成为电站锅炉的主要炉型,一般采用添加石灰石固硫。分析了CFB锅炉排烟热损失的影响因素,建立了CFB锅炉排烟热损失的数学模型,计算了我国首台CFBB在BECR工况时的排烟热损失,定量分析了各种因素的影响程度,提出了技术对策。
Heat loss due to exhaust gas is the largest heat loss of boiler,which affects the thermal efficiency greatly.The 300MW CFB boiler has became the main type of electric power station boiler in china,which desulfate with the Limestone.Influencing factors of limestone desulfurization of CFB boiler on boiler efficiency is described.New mathematical model for heat loss due to exhaust gas of CFB boiler is deduced.Heat loss due to exhaust gas of the frist 300MW CFB boiler in china is calculated under BECR.Influencing extent of factors are analyzed quantatively.Based on which technical measures are presented.
