Continuous Mesh Belt Firing Furnace

05/11/2012 12:28 PM

1. Hello, I am trying to figure out a fabricated heat exchanger/ cooling system for a facilities' furnace system. So far, we have put 4 large fans underneath the belt furnace along with a self made heat exchanger pipe at the cool down section and this is doing an ok job but what is the best way for the cool down length in a continuous firing furnace?

The cooling section of the furnace could have a water jacket composed of a heat exchanger, chiller, and pump. The water temp should be kept around 20-40C and continually circulating.

Air cooling, even assisted by blowers, has very wimpy heat flux (~ 1 W/cm2) so liquid cooling makes more sense. Another consideration is which direction the fans blow: toward the heated surface or away from it? Sucking hot air away from the surface by an exhaust fan is better than blowing the heat around by blasting the surface with recirculated hot air.
