Abstract

The invention relates to the technical field of industrial combustors, in particular to a low-nitrogen energy-saving combustion device which comprises a fuel gas inlet, an air inlet, a fuel gas channel, a mixing channel and a mixing outlet, the air inlet and the mixing outlet are communicated with the two ends of the mixing channel, the fuel gas inlet is communicated with the fuel gas channel, and the mixing outlet is communicated with the mixing channel. The gas channel is arranged on the periphery of the mixing channel in a surrounding mode, the section of the mixing channel is gradually reduced in the direction from the two ends to the middle, and gas distribution holes communicated with the gas channel are formed in the middle of the mixing channel in a surrounding mode. Therefore, the design is simple, the process is simple, and the cost is low; fuel gas and air are fully mixed, and the combustion efficiency is high, so that a hearth is uniform in heat tolerance, the emission reduction effect is remarkable, energy consumption is greatly reduced, economic benefits and social benefits are remarkable, and clean combustion and clean emission are promoted and achieved.

Description

technical field [0001] The present application relates to the technical field of industrial burners, and more specifically, relates to a low-nitrogen energy-saving combustion device. Background technique [0002] Burner (spray gun, burner, etc.) is a tool commonly used in industry. Combustion heating device. Burner is a common name for the combustion device used on industrial fuel furnaces. The key combustion device used above usually refers to the body part of the combustion device, which has a fuel inlet, an air inlet and an injection hole, which play the role of distributing fuel and combustion-supporting air and ejecting them in a certain way before burning. However, the existing burner has unreasonable air-fuel ratio, insufficient mixing, low combustion efficiency, resulting in uneven temperature in the furnace and temperature difference in the cross-section of the furnace cavity, high energy consumption, low efficiency, high NOx emissions, and cannot meet the national ...
