| Abstract: |
| Using Monte-Carlo method to calculate the radiant heat transfer in the hearth of cylindrical furnace, the compara tive calculation including gas temperature distribution of the hearth and calorific intensity of furnace tube was done，taking gas absorption coefficient as constant and as function of flue gas. The results show that the gas absorption coefficient has much effect on the calculation results. When the gas absorption coefficient varies with the temperature, concentration changing, the distribution of temperature and the tube surface calorific intensity and heat load value correspond to the facts. |
