The beneficial effect of the invention is that the single-ring combustion device provided by the invention includes a mixing tube and a furnace head. The mixing tube is a stainless steel sheet metal part. A mixing flow channel is formed inside the mixing tube. One end of the mixing tube has an air inlet, and the other end of the mixing tube has an air outlet. The mixing flow channel is connected between the air inlet and the air outlet. The furnace head is a copper part. The furnace head includes an inner ring part and an outer ring part. An annular flow channel is formed between the inner ring part and the outer ring part. The lower end of the inner ring part and the lower end of the outer ring part are connected to the other end of the mixing tube, so that the furnace head is assembled at the air outlet of the mixing tube. The mixing tube of this invention uses stainless steel sheet metal, which can reduce environmental pollution caused by production, reduce the use of materials and weight, and is corrosion-resistant. The stainless steel mixing tube is combined with a copper furnace head to reduce thermal deformation, while avoiding problems such as red fire and increased exhaust gas.
