Description

Low-nitrogen oxygen combustion equipment Technical Field The application relates to the field of low-nitrogen combustors, in particular to low-nitrogen oxygen combustion equipment. Background The low-nitrogen burner is a device which is added with a blower, an induced draft fan and a frequency converter on the traditional burner, and controls clean energy to enter the boiler by using a control valve and an integrated circuit, thereby providing more efficient heat energy for the boiler. The low-nitrogen burner can reduce the nitrogen oxide content in the combusted exhaust gas, and has low environmental pollution. The existing low-nitrogen burner can fully burn the gas fuel by mixing the gas fuel and air, so that the generation of nitrogen oxides after the fuel is burnt is reduced, nitrogen oxides are easily generated by nitrogen substances when the gas fuel is burnt and the local temperature is too high or the oxygen content is too high, the atmospheric pollution is caused, and the nitrogen substances can be converted into nitrogen gas when the fuel is burnt by mixing the air and the gas fuel, so that the pollution is reduced.
