摘　　要：推导了链条炉排加煤粉复合燃烧锅炉炉膛的物质平衡方程和上下炉膛的烟气热平衡方程 ,方程中考虑了上下炉膛间的辐射换热 .用直接计算辐射换热量的方法 ,推导了炉膛的辐射换热方程 .这些方程联立求解 。This paper deduced the equations of the mass balance of boiler furnace of mixing burning of endless grate with pulverized coal and gas heat balance equations between its upper part and lower part. The equations made some considerations to the radiant heat interchange between the upper part and lower part of the furnace. The radiant heat transfer equations of the furnace were deduced by the method of direct calculating heat interchange of radiation.Finding solutions by the simultaneous equations can make heat transfer calculation for this kind of boiler furnace.
