Coal Fired Boiler / Heat Exchanger
The JRF model coal fired hot air generator is an indirect type of heat exchanger which provides clean hot air after the heat transfer. With a high heating efficiency that reaches 60-75%, the coal fired furnace features a compact structure, safe operation, and a price half of that as other industrial coal furnaces of the same capacity.
Both the direct coal fired hot air generator and indirect coal fired hot air generator use a high temperature-resistant design that has a longer life span than other kinds of coal furnaces. This special design also prevents dust collecting on the heat exchanger and promotes a stable temperature output.
Besides coal, the JRF heat exchanger can also burn wood, charcoal, husks or other biomass products.
