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.
