A way to improve combustion efficiency and reduce no x low nitrogen burner

Abstract

The invention discloses a low-nitrogen combustor with combustion efficiency improving and NOx emission reducing effects. The low-nitrogen combustor comprises a combustor body, three supporting legs are welded below the outer surface of the combustor body in an annular array mode, moreover, a supporting plate is welded among the three supporting legs, an air blower is fixedly installed on the uppersurface of the supporting plate, the air blower is electrically connected with an external power source, an air outlet of the air blower communicates with the bottom end of a communicating pipe, andthe outer surface of the communicating pipe is connected with a pipe sleeve a in a sleeved mode. A flow swirling air cover, flow swirling plates and the communicating pipe are arranged, and the plurality of flow swirling plates form flow swirling channels so that air blown through the air blower can enter the flow swirling air cover through the communicating pipe, and can enter the flow swirling channels under action of the flow swirling plates to form a swirl flow, then the air can rise in a spiral mode, then the air enters an air inlet cover, and is sprayed out through a through hole b to bemixed with fuel gas, so that the inflow of the air is increased, contact between the air and the fuel gas is more sufficient, and the combustion efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of low-nitrogen burners, and in particular relates to a method for improving combustion efficiency and reducing NO X low NOx burner. Background technique [0002] Low nitrogen combustion is the formation of nitrogen oxides as part of the combustion reaction: the nitrogen oxides generated by combustion are mainly NO and NO 2 , collectively referred to as NO X , affecting fuel-type NO X There are many factors for formation, which are related to temperature, oxygen content, reaction time, and physical and chemical characteristics of coal powder. During the combustion of fuel, NO in the atmosphere X After dissolving in water, it will form nitric acid rain, which will cause extensive harm to the environment and cause huge economic losses, such as: corroding buildings and industrial equipment; destroying open-air cultural relics; damaging plant leaves, leading to forest death; Kill the fish and shrimp in the l...

Problems solved by technology

[0003] During the working process of the original burner, the gas and air are directly passed into the burner body for combustion operation, and the combustion efficiency is not high, resulting in excessive NO production during the combustion process. X , thereby polluting the environment
