The principle of the return air stove is based on the distribution of heat during the fuel combustion process. The heated object absorbs the heat and then reuses it: that is, it makes full use of the waste heat from the flue and reduces the heat. emissions.
The basic shape of a return air stove is a horseshoe-shaped internal structure with a gap facing the stove door. When lighting a fire in a horseshoe-shaped stove, use the suction force of the flue to push the fireworks out of the horseshoe space and then into the flue along the outer edge of the horseshoe. This increases the heating area of the bottom of the pot. Achieve the goal of fuel saving and rapid heating. The distance between the upper edge of the horse's hoof and the bottom of the pot should be determined by the actual operation.
Suction. A wood stove is a stove used to burnr firewood. The fuel it contains needs oxygen from the air to facilitate combustion. The more fuel there is, the more air is required. If air only enters through the gaps in the grate, it cannot reach combustion. support needs. It will burn incompletely, so it absorbs air better.
