[0003] In the combustion chamber, the exhaust combustion chamber (waste heat utilization) injects combustible gas into the combustion burner for combustion heating, and the high-temperature flame and flue gas generated by combustion at the burner heat the materials in the chamber.

[0004] It is found in the process of open-flame combustion of combustible gas that when the combustible gas burns at the burner, sometimes it cannot be fully burned, resulting in waste of combustible gas and problems of tail gas emission. Content of the Utility Model

[0005] To solve the above problems, the utility model aims to propose a burner air-blowing combustion assisting device, which blows a large amount of combustion assisting gas into the burner through a blower, so that the combustible gas at the burner can be fully burned, improving the utilization rate of combustible gas and reducing costs and increasing efficiency.

[0006] To achieve the above object, the technical solution of the utility model is realized as follows:

[0007] A burner air-blowing combustion assisting device includes a blower, a blowing pipeline, a flange valve and a high-temperature resistant pipeline. The blower is connected to the blowing pipeline, and the end of the blowing pipeline is connected with a high-temperature resistant pipeline through the flange valve. The flange valve is installed at the tail of the burner, and the high-temperature resistant pipeline is located inside the burner for outputting combustion assisting gas.

[0008] Further, a plurality of hollow openings are circumferentially arranged at the end of the high-temperature resistant pipeline.

[0009] Further, the hollow openings are located between the combustible gas inlet pipeline and the flame port of the burner.

[0010] Further, the flange valve is a high-temperature resistant sealed flange valve.

[0011] Further, the high-temperature resistant pipeline is a pipeline made of Cr 25 Ni 20 material.

[0012] Further, the diameter of the high-temperature resistant pipeline is 1 / 3 of the diameter of the combustible gas inlet pipeline of the burner.

[0013] Further, the combustion assisting gas is air.

[0014] Beneficial effects: After combustible gas is introduced into the burner and ignited, the blower is turned on. A large amount of combustion-supporting gas is blown into the burner through the blower, the air duct, the flange valve, and the high-temperature resistant pipeline, so that the combustible gas at the burner is fully burned, improving the utilization rate of the combustible gas, reducing costs and increasing efficiency. The utility model enables the combustible gas to be fully burned, effectively improves the risk of combustible gas leakage, and the exhaust gas generated after full combustion is also more environmentally friendly and clean, effectively reducing the exhaust gas treatment cost.
