摘要
Abstract
The effects of combustion modes,namely space combustion and wall-fired combustion, on the heat flux distribution in a double-side radiation box furnace were investigated by means of the Monte Carlo method. It was showed that,in the space combustion,the simulation results for the furnace temperature and the average heat flux of the furnace tube were consistent with industrial data basically. The simulation for the radiant heat transfer process had good applicability to the double-side radiation box furnace. The heat flux distribution of the wall-fired combustion was improved compared to that of the space combustion,the peak heat flux reduced from 58.0 kW/m2 to 52.5 kW/m2,and the uneven coefficient of the heat flux reduced from 4.6 to 3.7,which was beneficial to the reduction of the local heating of the tubes. The average heat flux of the wall-fired combustion was slightly higher than that of the space combustion,which was because the radiation ability of the wall was stronger than that of flue gas.关键词
