Abstract

The invention provides a heat accumulation type radiant tube burner. The heat accumulation type radiant tube burner comprises an air cylinder, a reversing valve, air cavities, a radiating pipe, ignition assemblies, heat accumulators, jet discs and combustion cylinders, wherein the reversing valve is connected with the air cylinder to control the air flow direction, the air cavities are connected with the reversing valve, the radiating pipe is connected with the air cavities and comprises two opposite cavities and a connecting cavity, one ends of the two cavities are respectively connected withthe air cavities, and the other ends of the two cavities communicate through the connecting cavity; and one end of each air cavity is provided with the ignition assembly, the heat accumulator, the jet disc and the combustion cylinder, and the heat accumulators, the jet discs and the combustion cylinders are sequentially arranged in the corresponding cavities according to the direction from one ends of the cavities to the other ends. The heat accumulation type radiant tube burner solves the technical problems that the nitrogen oxide discharge amount of a heat accumulation type radiant tube burner is large, and the discharge standard is not met. The heat accumulation type radiant tube burner achieves the technical effects of realizing grading mixing of air and coal gas, achieving grading combustion, avoiding the occurrence of local high-temperature areas, effectively reducing the generation of nitrogen oxides and meeting the national emission requirements.

Description

technical field [0001] The invention relates to the technical field of regenerative radiant tube burners, in particular to a regenerative radiant tube burner. Background technique [0002] Regenerative combustion technology is a technology that burns under high-temperature and low-oxygen air conditions. The main point of its working principle is that the regenerator as a heat carrier is periodically heated by high-temperature gas, and releases heat to low-temperature gas to realize heat transfer. transfer. It can improve energy utilization, especially the rational use of low-calorific-value fuels, which not only reduces pollutant emissions, but also saves energy. It has become an advanced technology that meets current resource and environmental requirements. At present, the domestic regenerative combustion technology is effective in steelmaking roasters, hot rolling furnaces and other processes. However, for high calorific value gas and applications in small combustion spac...
