Industrial Heat Transfer Type Gas Fired Hot Air Furnace
1.Introduction to gas hot air furnace
Heat transfer gas (oil) hot air furnace with all-welded plate heat exchanger structure. High temperature flue gas from natural gas combustion will be exchanged for high temperature clean air through heat exchange plates, which are used to heat and dry foods, medicines and other products that require high heat sources.
2. advantages of gas-fired hot air furnace
1. Compared with the traditional tubular hot air furnace, the structure is compact and the floor area is small.
2. The highest heat exchange air temperature can reach 600℃.
3. Low exhaust temperature, the exhaust temperature of the exhaust gas can be reduced to 100℃, improving the heat exchange efficiency.
4. The contact medium is made of high quality stainless steel, which is pollution-free to the medium. It is widely used in the pharmaceutical, food and other industries with high requirements for the medium.
