Abstract

The invention provides a low-nitrogen combustor. The combustor comprises a combustor barrel body, a combustor head cover and a fuel gas injection device; one end of the combustor barrel body is fixedly connected with the combustor head cover; the fuel gas injection device comprises a main fuel gas injection pipe and auxiliary fuel gas injection pipes, wherein the auxiliary fuel gas injection pipescommunicate with the main fuel gas injection pipe, the pipe diameter of the main gas injection pipe is greater than that of the auxiliary fuel gas injection pipes, auxiliary fuel gas nozzles are arranged at the tail ends of the auxiliary fuel gas injection pipes, and a plurality of small circulation holes are formed in the tail end of the main fuel gas injection pipe; and the end, away from the auxiliary fuel gas injection pipes, of the main fuel gas injection pipe is arranged in the combustor barrel body, and the end, close to the auxiliary fuel gas injection pipes, of the main fuel gas injection pipe and the auxiliary fuel gas injection pipes are all arranged in the combustor head cover. According to the technical scheme, the effects of high combustion efficiency and low NOx emission can be achieved.

Description

technical field [0001] The invention relates to the field of combustion equipment, in particular to a low-nitrogen burner. Background technique [0002] With the development of society, air pollution is becoming more and more serious, and it is urgent to deal with environmental problems. As an important precursor of PM2.5, NOx has become one of the key points of atmospheric governance. Fine particulate matter (PM2.5) in smog is extremely harmful to the human body, so the control of dust, particulate matter, nitrogen oxides, and CO2 is particularly critical. The continuous increase of nitrogen oxide content in the air will accelerate the rate of fine particulate matter (PM2.5). ) and the formation of secondary aerosols are important reasons for the formation of acid rain, photochemical smog and haze weather, and the control of nitrogen oxide pollution has become one of the most important measures to prevent air pollution. With the implementation of the latest "Emission Stan...
