Theoretical study on reducing thermal pollution problem of industrial furnace wall
减少工业炉炉壁热污染问题的理论研究

According to the characteristics of the heat dissipation of industrial furnace wall, the mathematics model of its heat dissipation was established, and the SIMPLE method was adopted to solve these dimensionless equations,obtained that main heat loss of furnace body is between 0 and 0.1 of Y coordinate.This paper analyzed the capacity of the heat recycle after fixing plates for heat protection,through testing and calculating the heat dissipation of existing furnace wall.The result shows that the heat dissipation will fall from 1 524.8 W/m2 to 60.1 W/m2 exhausted to ambiencein. Under the almost similar condition,at the same time,the heat 404 kW can be reclaimed,the heat pollution was greatly reduced.
