Surface burner for heating stove using methanol liquid fuel

The utility model discloses a surface combustor for a heating stove using methanol liquid fuel, and belongs to the technical field of combustion equipment. According to the technical scheme, the structure principle of a surface combustor using methanol fuel is adopted, the speed of methanol gas entering a premixing chamber is reduced through a speed reduction nozzle, under the action of high-speed vortex airflow, the airflow path of the methanol gas reaching an inner cavity of the combustor is greatly increased, the burn-off rate is increased, and carbon monoxide is reduced. The turbulent flow type passive mixer effectively pre-mixes gasified high-temperature methanol gas and combustion-supporting air, the distance from a pre-mixing chamber to a surface combustor is shortened, the combustion stability is improved, and combustion thermal vibration is prevented. The circular tube type surface combustor is made of a heat-resistant stainless steel sheet, fine fire holes are distributed in the circumferential surf
