Problems solved by technology

[0003] 1. At present, small-scale heat exchange equipment tends to be compact in structure, and its combustion chamber space is relatively small. The horizontal electronically controlled diesel burner with pressure swirl diffusion combustion is used, and the flame length is long, which causes the flame to form in the heat exchange equipment combustion chamber partial fire, uneven heating, poor adaptability and other problems
[0004] 2. For the burner that adopts the pressure swirl diffusion combustion method, the flame temperature area is unevenly distributed, and the combustion range of the fuel particles is short, which cannot be evenly and fully burned, resulting in a large amount of NO x Discharged into the atmosphere with flue gas

Abstract

The present application relates to the field of burners, and in particular, to a combined device and a control method for realizing low-nitrogen short flame combustion of diesel burners. The combined device includes an adjustment device, a combustion cylinder, an end cylinder, a double swirl flame stabilization disc, a nozzle and an ignition assembly. The end cylinder is fixed at the front end of the combustion cylinder, the double swirl flame stabilization disc is fixed inside the front end of the combustion cylinder, and the adjustment device is installed in the combustion cylinder. Inside the middle section of the barrel, the nozzle is fixed inside the middle section of the combustion barrel, and the adjusting device, the combustion barrel, the end barrel, the double swirl flame stabilization disc and the nozzle are all coaxial. The application changes the combustion air distribution ratio, strengthens the air supply guidance and ejected flue gas recirculation combustion, increases the swirl air distribution intensity on the premise of ensuring flame stability, increases the turbulence of the oil mist flame, and shortens the flame length. Strengthen air disturbance, enhance oil and gas mixing effect, and inhibit NO x It strengthens the air gathering effect on the flame and shortens the flame length; ejects the high temperature flue gas back to participate in the secondary combustion and reduces NO x emissions.

Description

technical field [0001] The present application relates to the field of horizontal electronically controlled diesel burners with forced air supply, and in particular, to a combined device and a control method for realizing low-nitrogen short flame combustion of diesel burners. Background technique [0002] At present, the horizontal electronically controlled diesel burners used in the market are mainly designed for use with boilers. When installing small heat exchange equipment, there is a problem of flame adaptability, mainly in the following aspects: [0003] 1. At present, small heat exchange equipment tends to be compact in structure, and its combustion chamber space is relatively small. Horizontal electronically controlled diesel burners with pressure swirl diffusion combustion are used, and the flame length is long, resulting in the formation of flames in the heat exchange equipment combustion chamber. Slanted fire, uneven heating, poor adaptability, etc. [0004] 2. F...
