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.
It produces high temperature flue gas in the furnace by burning of coal, going into smoke ring under the action of fan, and after the heat exchanging with the outside air, through the flue gas ducting and then discharged by chimney, the cold air blows into the shell of the stove by blower, getting into furnace lateral air ring through furnace arch the stove chamber into the lateral air ring, and supply clean hot air equipment by hot air outlet piping.
1. The fuel is coal/wood pellet/biomass
2. The hot air furnace use the pure hot air as the medium, no pollution.
3. Low power consumption, high thermal efficiency.
4. Auto measuring temperature and displaying.
5. Simple operation, easy to use. The equipment is all from domestic, its performance guideline reach to national advanced level.
