Abstract

The invention relates to the technical field of natural gas clean combustion, and provides a novel low nitrogen oxide gas burner structure. Air is divided into two stages through a natural gas channeland an auxiliary gas channel to form staged combustion. Through the joint action of a natural gas swirl flow branch pipe and a gas swirl flow device, the evenly distribution effectof fuel is achievedin the radial direction of the burner,reasonable flow field distribution ofmixture airof the fuel and auxiliary air is formed at the outlet of the burner, the mixture air ratio is reasonable, mixtureis even, and a combustion area is reasonably controlled, combustion stability is ensured, and the extremely low nitric oxideemission effect is achieved.

Description

technical field [0001] The invention relates to the technical field of natural gas clean combustion, and in particular provides a novel low-nitrogen oxide gas burner structure. Background technique [0002] During the combustion of fuel, the formation of nitrogen oxides is part of the combustion reaction: the nitrogen oxides generated by combustion are mainly NO and NO2, collectively referred to as NOx. NOx in the atmosphere is an important factor that causes acid rain and smog, which brings extensive harm to human life and the environment, and causes huge economic losses. [0003] With the increasing environmental protection requirements, the NOx emission requirements are also becoming increasingly stringent. In recent years, clean combustible gas such as natural gas has been widely used in production and life because of its advantages of safety, high efficiency, easy operation and low emission. However, there is still a lot of room for improvement in the NOx emission of ...
