LRF series biomass hot air furnace is a device that uses hot air to heat materials, providing high-temperature hot air, widely used in various heating and drying requirements. Its basic working principle is to generate high-temperature flames and combustion products through fuel combustion, and then provide sufficient air through fans or pneumatic combustion devices to ensure the complete combustion of the fuel and generate high-temperature hot air. These hot air are conveyed to the designated heating areas through heat exchangers, such as industrial furnaces, etc. Its products feature compact structure, easy installation, rapid heating and clean hot air, and are deeply loved by users.

Main Feature
1.The output is clean hot air, which is environmentally friendly, qualified and pollution-free.
2. It is easy to operate, safe and stable.
3. Automatic control, simple and convenient.
