Problems solved by technology

The existing oxygen-enriched flat-flame burner patent is to mix oxygen into the air, and realize flat-flame combustion through the double swirl of gas and oxygen-enriched air. Considering that oxygen-enriched combustion will bring about a sharp increase in flame temperature, at the same time The oxygen-enriched concentration is limited by the safety range of the air pipeline for the oxygen concentration in the oxygen-enriched air, so the present invention provides a new flat flame burner structure

Abstract

The invention relates to an oxygen-enriched flat flame burner and a using method, and belongs to the field of burners. The oxygen-enriched flat flame burner comprises a burner body; the burner body comprises a gas channel for gas introduction, an air channel for air introduction, oxygen channels for oxygen or air introduction and burner bricks; a combustion channel is arranged in the burner bricks; the gas channel, the air channel and the oxygen channels all communicate with the combustion channel; the multiple oxygen channels are uniformly arranged in the burner bricks in the circumferentialdirection of the axis of the burner; the gas channel is arranged on the axis of the burner; and the air channel is arranged on the outer ring of the gas channel. The burner can work in three modes ofair supporting combustion, oxygen-enriched air supporting combustion and oxygen supporting combustion. The burner gives full play to the application potential of oxygen-enriched combustion in the flatflame burner, and effectively realizes energy conservation and emission reduction.

Description

technical field [0001] The invention belongs to the field of burners, and relates to an oxygen-enriched flat flame burner and a use method thereof. Background technique [0002] Oxygen-enriched combustion is the combustion of oxygen-containing gas that is higher than the oxygen content of air (20.947%). It is an effective energy-saving combustion technology and is widely used in the iron and steel industry. Metallurgical heating furnace is one of the important processes in steel rolling production. One of the main energy consumption, oxygen-enriched combustion has a remarkable effect in energy saving and emission reduction, and has a very broad application prospect in metallurgical heating furnaces. Straight flame burners, regenerative burners, and flat flame burners are commonly used in metallurgical heating furnaces. The existing oxygen-enriched flat-flame burner patent is to mix oxygen into the air, and realize flat-flame combustion through the double swirl of gas and oxy...
