Product Description
Coal Fired Hot Air Furnace
1. Introduction for Coal Fired Hot Air Furnace
The direct fired furnace is a style of heater in which a burner provides hot gasses that transfers their heat energy for drying final products. It's customized designed and manufactured according to customer's detailed requirements.
Oil, natural gas and other fuel can combust to produce high temperature clean flue gas through oil or gas burner, and the flue gas can provide the hot air to the drying system directly as heat source or heating the air with the heat exchanger as heat source.
2. Working principles
When the fuel is burned in firebox,high temperature smoke gas is produced. Those smoke gas is sent byhot air furnace which has strong exchange heating function to dried air. After quantity of heat is emanated,hot fueling gas temperature is decreased to 250°C and those gas are exhausted by fan. Fresh air is sent to hot air furnace by selected blow fan machine. After absorbed heating energy, when air temperature reaches to specific degree, it is sent to outlet of hot air,while hot air temperature meet the highest limited point,the burner will stop burning automatically or turn to small fire burning, when hot air temperature decreases to the lowest preseted degree, burner start running again, the speed of heating can be adjusted by air inlet valve.

4.Advantages for Coal Fired Hot Air Furnace
1) It can burn multi-coal (Biomass).2) High combustion efficiency, Thermal efficiency is more than 95%,3) The output of the heat load is very stable. As to the mechanical combustion, it is simple to operate and easy to adjust;4) The hot air is very clean and the dust content is from 30 to 120mg/Nm3.5) The hot air temperature below 1200°C is easy to adjust. The fluctuation range of continuous hot air temperature is about ± 5 ºC.6) Equipment durability, low operating costs, easy maintenance.
