Low-NOx low-CO efficient energy-saving combustor

Abstract

The invention discloses a low-NOx low-CO efficient energy-saving combustor. The low-NOx low-CO efficient energy-saving combustor comprises a combustor shell. A combustion chamber body is mounted at the top end of the combustor shell. An inner cavity of the combustion chamber body is a combustion chamber. A combustor closing opening is formed in the top end of the combustion chamber body. A secondary nozzle with a flow guide pipe is arranged outside the top end of the combustion chamber. Fuel gas sprayed out of a main gun is mixed with air entering the combustion chamber at a high speed, and therefore low-temperature oxygen-enriched main flames are formed in the combustion chamber, and generation of NOx and CO is reduced. The fuel gas sprayed out of each combustor auxiliary gun can draw smoke into the secondary nozzle with the flow guide pipe from the position of a smoke backflow channel, and then the smoke is sprayed into the main flames through the secondary nozzle with the flow guide pipe to be combusted. Due to the fact that a large amount of smoke is contained, the combustion intensity is reduced, generation of NOx is reduced, the fuel gas leaked into the smoke of the combustion chamber is reduced, and formation of CO is reduced.

Description

technical field [0001] The invention relates to the technical field of energy-saving burners, in particular to a low-NOx, low-CO, high-efficiency energy-saving burner. Background technique [0002] Generally, low NOx burners adopt the low NOx technology of air classification and fuel classification. This kind of burner generally has problems such as low combustion efficiency and high CO content, especially when the furnace temperature is lower than 600 ° C, the gas emitted in the flue gas The CO content is as high as hundreds or thousands of PPM. Several times or hundreds of times more than the environmental protection requirements, that is to say, it wastes energy and damages the environment, and at the same time, it brings the personal safety of operators. [0003] The main reason is that after the fuel from the sub-gun is mixed with the flue gas, most of it is sprayed into the main flame for combustion, and the other part is dispersed in the combustion chamber, and the i...
