Product Description
The hot air furnace combustion chamber and heat exchanger in one combined, using the structure of full steel plate multi-layer sleeve type, it's consumption chamber in the below of furnace center, circles heat exchanger in the upper and around, air and flue gas are two-pass, flow separately in heat exchanging. In order to improve thermal efficiency, the multiple head helical groove plate heat exchanging technology and turbulent flow principle, thinning laminar flow thickness, make the air and flue gas constantly exchange revolving on the march, greatly strengthened the heat transfer effect.
