Combustion and Emission Study of Ejector Structure Burners Used in Gas Boilers
In order to achieve the"carbon peaking and carbon neutrality"goals,natural gas,as a clean and efficient low-carbon fossil energy,shoulders the important mission of transitioning the energy consumption structure from high-carbon pollution to low-carbon.In order to solve the problem of high nitrogen oxides in natural gas burners used in gas boiler,a burner with an ejection structure was designed,and two different tapering gas nozzles and straight nozzles were designed,and the spacing between the nozzle and the ejector was studied.The results show that the tapering burner furnace with an ejection structure has the lowest NOx emissions.Especially,the NOx emission in the burner with nozzle extension type is 40.88％lower than that without the ejection tube,and the NOx reduction effect is the best.
