| Abstract: | The mathematical simulation method is mentioned in this paper of calculating the heat transfer in a furnace of 300MW W-shape pulvenzed coal boiler. According to this method, the exchanged radiative thermal energy is calculated by Monte Carlo method, meanuhile, the calculation of convection and conduction in the furnace is performed by definite difference method. By using this method, the satisfied temperature distribution in the furnace is figured out. In the end, several problems about Monte Carlo method is alsodiscussed in this paper. |
| Keywords: | W-shape flame boiler heat transfer in the furnace Monte Carlo method |
