- Abstract:
- The flame characteristics in the double preheated regenerative annular furnace were simulated by using the RNGκ-ε turbulence model, the non-premixed (PDF) combustion model and the anisotropically scattered P-1 radiation heat transfer model, and the effects of different air injection angles and different preheating temperatures on the flame characteristics were compared. The results show that the volume of flame is larger when the air injection angle is 5°, but the loss of incomplete combustion is more. When the injection angle is 30° and 40°, the flame volume is relatively small, and the maximum combustion temperature is high. When the injection angle is 10°~20°, the comprehensive characteristics are better. The increase of preheating temperature improves the combustion stability, so that the maximum combustion temperature and the average combustion chamber temperature increase significantly.
