Gas burner with low NOX

Abstract

The invention relates to the technical field of clean gas burning, in particular relates to a gas burner with low NOX, which aims to further reduce the pollutants, especially the generating amount of NOX caused by the gas burner, and simultaneously improves the efficiency of a whole boiler. The gas burner disclosed by the invention integrates the technologies of enhancement of the mixing of gas and combustion air, graded and sectioned burning, burning of thick gas and thin gas, smoke circulation and the like, and can enhance the mixing of the gas and the combustion air so as to achieve the beneficial effects that the burning is reinforced, the peak value temperature of burning flame is reduced, and further the excess air coefficient of the burning is reduced, and the pollutants such as NOX and the like can be reduced to be minimum.

Description

technical field

[0001] The invention relates to the technical field of gas clean combustion, in particular to a low NO X gas burner. Background technique

[0002] Increasing environmental protection requirements, a large number of gas imports and successively discovered gas fields provide the necessary conditions for the development of gas burners; in addition, gas burners have the advantages of safety, high efficiency, low pollution, and easy operation, which inject strong impetus into market demand , thus bringing vitality to the development of gas burners. Gas burners have made considerable progress since they were applied, but there is still a certain distance between their pollutant emissions and excess air coefficients and the ideal goals. People are still trying to find various ways to reduce pollutant emissions and excess air coefficients. technical means.

[0003] The heat required by industrial boilers and heaters can be provided by burning the mixture of gaseou...
