Indirect clean hot air furnace

JLG-III series Indirect clean hot air furnace consists of a burner, a coal feeding device, a cinder removal chain conveyor and a heat exchanger, It takes coal as its fuel, and outputs clean hot air.

Product Introduction:

Range of application
This furnace is adaptable to such industries as grain processing, chemicals, printing and dyeing, dregs drying, feedstuff, fertilizer, building material, and mining etc..

Indirect clean hot air furnace

Product Working Principle:

Different from direct heating coal-fired furnace, indirect heating coal-fired hot air furnace is mainly adaptable to that drying equipment for dry material not permitted to pollution, or applies to low temperature heat sensitive material, such as dryers for cereal grain, milk powder, pharmacy, synthetic resin and fine chemicals etc.. Indirect coal-fired hot air furnace adopts all steel heat exchanger to effectively prevent some harmful components like soot or sulfides entering into the drying process to affects the quality of cereal grain.
