1.Hot Air Oven of Working Principle:

The hot air stove combustion chamber and heat exchange in one combined, using the structure of full steel plate mufti-layer sleeve type, it's consumption chamber in the below of furnace center, circles heat exchange 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. 

2.Hot Air Oven of The main work process: 

The Hot Air Oven produce high temperature flue gas in the furnace by burning of coal, go 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 blow 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

3.Hot Air Oven of Main Equipment:

The hot air stove mainly consists of the grate stoker, refractory bricks, baffle board, hot air stove proper, the flue gas ducting and wind inlet pipe, dust collector, chimney and its bracket, induced draft fan (including adjusting valve), blower (including adjusting valve) and special temperature measuring instrument etc. 

4.The Hot Air Oven of Performance Characteristics:

1. The fuel is diesel oil,light oil,heavy oil,natural gas,coal gas. 

2. The hot air boiler use the pure hot air as the medium, no pollution. 

3. Low power consumption, higher thermal efficiency. 

4. Auto measuring temperature and displaying. 

5. Simple operation, easy to use. The equipment are all from domestic, its performance guideline reach to national advanced level.
