Advantageous effects

After the scheme is adopted, the invention has the following advantages:

2. The outer surface of the furnace body inner plate is provided with the plurality of turbulence parts, and compared with the furnace body inner plate with a plane surface, the furnace body inner plate with the turbulence parts on the outer surface has the advantages that on one hand, the outer surface area of the furnace body inner plate with the turbulence parts on the outer surface is larger, so that the contact area between the furnace body inner plate and air entering the ventilation channel is large, and on the other hand, the turbulence parts of the furnace body inner plate can damage the boundary layer of the air in the ventilation channel to enable the air in the ventilation channel to form turbulence at the turbulence parts, so that the retention time of the air in the ventilation channel is prolonged; the heating effect of the inner plate of the furnace body on the air entering the ventilation channel can be improved, so that the temperature difference between the air entering the combustion chamber from the air vent and the inside of the combustion chamber is smaller, and the combustion efficiency can be further improved.

3. The turbulence part of the furnace body inner plate is at least one of a concave part and a convex part. The temperature of the concave turbulence part is higher, the heat conduction effect of the air in the ventilation channel is better, the distance between the convex turbulence part and the outer plate of the furnace body is shorter, the heat radiation effect of the convex turbulence part and the outer plate of the furnace body is better, and the heating effect of the side face of the furnace body is improved.

4. Theoretical analysis, simulation calculation and specific tests show that the height of the concave and/or convex of the turbulence part of the furnace body inner plate is not more than half of the distance between the inner wall and the outer wall. The main reasons are: if the height of the concave and convex parts is too high, namely more than half of the distance between the inner wall surface and the outer wall surface, the air flow can be directly reduced, the heat conduction and heat radiation effects brought by the concave and convex parts are offset, and the combustion sufficiency is influenced.
