Embodiment

[0033] Embodiment: Affect NO in gas combustion process x The main factors of formation are combustion temperature, residence time of fuel in the high temperature zone, and the mixture of fuel and air. Correspondingly, low NO x Combustion methods include reducing the gas combustion temperature, strengthening the rapid mixing of gas and air, and eliminating local high temperature areas.

[0034] The present invention is described in further detail below in conjunction with accompanying drawing:

[0035] see Figure 1 to Figure 4, the present invention is a low NOx gas burner with variable load flexibility adjustment, which is composed of an air supply pipeline, a gas supply pipeline and an igniter pipeline 15. Among them, the air supply pipeline includes a primary air inlet 1, a secondary air inlet 2, an air volume regulating valve 3, a primary air flow channel 4, a secondary air flow channel 5, a secondary air branch pipe 6 and an air cyclone 7; the gas supply pipeline Inclu...

Abstract

The invention discloses a low-NOx gas burner capable of realizing flexible adjustment of variable loads. The low-NOx gas burner comprises an air supply pipeline, a gas supply pipeline and an igniter pipeline; the air supply pipeline comprises a primary air inlet, a secondary air inlet, a primary air flow channel, a secondary air flow channel, a secondary air branch pipe and an air cyclone; the gas supply pipeline comprises an inner ring gas inlet pipeline, an outer ring gas inlet pipeline, an inner ring gas flow dividing box, an outer ring gas flow dividing box, a center gas branch pipe, an inner ring gas branch pipe and an outer ring gas branch pipe. An air classification technology, an air rotational flow technology, an air porous dispersion jet flow technology, a gas load adjustable technology and a gas porous dispersion jet flow technology are adopted, and the problems that in the natural gas combustion process, it is difficult for the generation amount of nitric oxide to meet the ultralow nitrogen emission requirement, and serious pollution is caused to the environment are solved.

Description

technical field [0001] The invention belongs to the technical field of thermal energy and power engineering, and relates to a low NO x Burners, especially a low NOx gas burner with variable load flexibility adjustment. Background technique [0002] With the green transformation of energy structure and the proposal of carbon neutrality goals, my country's natural gas consumption continues to increase. Although natural gas is a clean energy, the nitrogen oxides generated during the combustion of natural gas will cause harm to the atmospheric ecological environment and people's health. Therefore, reducing the amount of nitrogen oxides generated in natural gas combustion has become a key issue that needs to be solved urgently in the process of natural gas combustion and utilization. Natural gas low-nitrogen combustion technology mainly focuses on how to reduce combustion temperature and thermal NO x At the same time, consider strengthening the rapid and uniform mixing of na...
