| 摘 要： | 以某热电厂450t/h循环流化床锅炉运行实测数据为基础,在锅炉密相区和稀相区分别建立热平衡方程式,计算循环流化床锅炉密相区、稀相区内的传热系数,并提出了稀相区内以对流为主的对流-辐射模型,新的计算方法可直接计算循环流化床锅炉稀相区辐射传热在总的传热中占的比率。图5参7

| Abstract: | Making use of actual data obtained with a 450t/h circulating fluidized bed boiler in a certain power plant, a heat transfer calculation of the dense and the sparse zone has been carried out and a new heat balance model for calculating heat transfer in furnaces as well as a heat transfer calculation method for the sparse zone is being presented. Figs 5 and refs 7. |
