An analytical method for the error of statistic simulation in the Monte-Carlo solution of 3-D furnace heat transfer is presented. The method begins with the analysis of radiative simulation between two small zones. Their behaviour is expressed as the process that the energy beams are emitted from point source and then do the random walk. Thus the expression of variance caused by the statistic simulation of the two zones is gained. In the whole furnace the radiative simulation is handled as the radiative simulation of many points sources which exist simultaneously. And this process is expressed being the simulating of the function which consists of a group of stochastic processes each corresponding, to one zone. Through this function we gain the expression of statistic simulations error in radiative transport term. On the basis of that, the expressions of simulations error in. furnace heat flux distribution and temperature distribution are discovered.An error analysis for the Monte-Carlo solution of a furnace of large boiler (HG-410/100-6 type) is carried out using the error expressions mentioned above. The result shows that owing to the difference of the position and physical parameters of the zones, the statistic error in every zone is different. While we make 1548 zones in the furnace and 6×105 energy beams in total the maximum fractional error of radiative simulation in the gas area is only 4 to 5 present at burning center but 20 to 28 percent at furnace outlet, and on the furnace wall is 10 percent at burner area, but 25 .to 30 percent at furnace outlet (Fig., 1,2). The maximum error of gas temperature is 20 to 60℃, and the maximum calculating error of surface temperature on the sooted furnace wall is 130 to 200℃ (Fig. 3).This paper discussed three problems. First, in the case of furnace heat transfer the va- riation of the total number of energy beams will produce different effect on the zones which possess different, positions and different properties. As to China made 410 t/b boiler if the furnace is divided to 1600 zones it seems proper to choose the total number of energy beams near s×105. Second, the example calculating shows that, the technic of "N∞ energy" is better than technic of "N = const". Third, in the present enginerring applying if the statistic error should be remained near the original level, the total number of en-ergy beams must be increased proportionally to the increase of furnace zones.
