Bio-Pellet Fuel Hot Air Stove is widely used as drying heat source for grain, food, medicine, tobacco, various agricultural by-products and various industrial materials, such as drying, printing and dyeing, painting, etc. It can also be used for heating tall factory buildings and plastic greenhouses. And the cooling and heating of underground mines, underground engineering and other occasions that need to be dried.

Combustion chamber and heat exchanger of Bio-Pellet Fuel Hot Air Stove are integrated, adopting all-steel multi-layer sleeve structure, the lower part of the furnace core is the combustion chamber, the upper part and the surrounding are annular heat exchangers, and the air and flue gas are both Double-circuit program, each going its own way, for heat exchange.
In order to improve thermal efficiency, the multi-head spiral groove sheet heat exchange technology and turbulent flow principle are adopted to thin the bottom layer of laminar flow, so that the air and flue gas continuously change the direction of rotation during operation, which greatly enhances the heat exchange effect.
The main working process of Bio-Pellet Fuel Hot Air Stove is: burning coal produces high-temperature flue gas in the furnace, which enters the smoke ring under the action of the fan, and after heat exchange with the outside air, it is discharged from the chimney through the flue; the cold air is discharged from the chimney The blower blows into the shell of the hot blast stove, flows into the air ring outside the furnace wall through the top of the furnace, and supplies the equipment requiring clean hot air through the hot air outlet pipe.
