At present, fuel combustion is used as a heat source for heating, and fireplaces, bonfire, charcoal fire pots, coal ball furnaces and the like are mainly used. Fireplace, bonfire, charcoal fire basin etc. are direct open fire heating, and the defect of direct open fire heating is: unsafe, smoke and ash are present, the air in the room is polluted, and the sanitation is not realized. The common indoor coal ball stove is an indirect heat source heating device, and utilizes the heat emitted when the pyrotechnics generated by coal ball combustion passes through a metal pipe to heat, so that the defect of direct open fire heating can be overcome to a certain extent, however, the device has an excessively simple structure, the pyrotechnics is directly connected to the outside of the room through the metal pipe, and the heat absorption is slow when the temperature of the metal pipe is high, and the heat efficiency is low.
These drawbacks can be overcome if indirect hot air heating is used. However, there is no suitable hot air heating device for home heating in daily life.
In the prior art, a hot blast furnace for producing useful biomass fuel by baking is characterized in that a high Wen Yanhuo generated by burning in a burning furnace passes through a heat exchange tube, then is discharged from a smoke exhaust tube, the heat exchange tube absorbs heat, and the heat absorbed by the heat exchange tube is changed into hot air through a fan to be sent to a baking room for drying. However, this biomass fuel hot blast stove also has drawbacks, mainly: because the inner wall of the heat exchange tube is smooth, the passing speed of heat (smoke) is high, and the heat efficiency is not high; moreover, miniaturization is inconvenient to adapt to house heating.
