【Abstract】 In this paper, the random emission model of energy beam and the differential power emission method for iteration(DPD method)are developed to cylindrical combustion furnace. The sample equations of Monte-Carlo method for radiative heat transfer in cylindrical combustion furnace and their deducing process are given. The using range of this method is opened up further. A numerical solution of three-dimentional heat transfer in a furnace(the vertical cyc-lone-fired boiler of type HG-670/140-2)is carried out by using this method. The calculated result is satisfactory.更多还原
