Abstract

The invention discloses a petal-shaped staged combustion gas low-nitrogen combustor. The combustor comprises a fuel gas collection tank, a combustion stabilizing disc, a nozzle and a combustion supporting channel; the nozzle is connected to one end of the fuel gas collection tank, and the combustion supporting channel extends to the tail end of the nozzle from an inlet of the fuel gas collection tank; the combustion stabilizing disc is arranged in the nozzle, and a gas chamber is arranged between the combustion stabilizing disc and the inner wall of the nozzle; the air chamber is connected to the fuel gas collection tank through a plurality of fuel conveying pipes, and a plurality of sector-shaped grooves which are evenly formed in the circumferential direction of the nozzle are formed in the tail end of the nozzle; a spray gun is formed in the position, in the circumferential direction of each sector-shaped groove, in each sector-shaped groove, and is connected with the gas chamber to obtain gas; and the combustion stabilizing disc comprises a center channel and a bending blade channel. The low-nitrogen combustor achieves staged combustion, nitric oxides are reduced, the combustion efficiency is not reduced, the current environment-friendly requirement is met, and meanwhile emissions of the nitric oxides are reduced to a greater extent.

Description

technical field [0001] The invention belongs to the technical field of burners, in particular to a petal-shaped staged combustion gas low-nitrogen burner. Background technique [0002] In recent years, a large area of ​​my country has continuously experienced smog weather, and the air pollution is serious, endangering the physical and mental health of the people. In view of the high level of nitrogen oxide emissions in my country and the great damage to the environment and human health, the control of nitrogen oxides in my country is urgent. Industrial emissions of nitrogen oxides are one of the main causes of smog weather. In order to reduce NOx emissions, the country has formulated new industrial boiler emission standards, and the new standards have become increasingly stringent. However, the emission of many industrial boilers in my country cannot meet the environmental protection requirements. Low NOx burners are one of the most economical and effective methods to reduc...
