The invention relates to a water-cooled heat storage combustor which comprises a gas pipe, a heat storage box, a fire outlet pipeline, heat storage bodies and an air pipe. The gas pipe is located in the heat storage box and above the fire outlet pipeline, the heat storage bodies are arranged on the right side of an inner cavity of the heat storage box in the horizontal direction and the vertical direction respectively, and the air pipe is arranged at the position, on one sides of the heat storage bodies, of the heat storage box. A circulating water cooling component is further included, and is arranged at the bottom of the heat storage box and the position of the fire outlet pipeline. The circulating water cooling component comprises a water inlet pipe, a water outlet pipe and a cooling water sleeve, the water inlet pipe and the water outlet pipe are arranged on the left side and the right side of the cooling water sleeve respectively, and the cooling water sleeve is of a multi-layer annular structure, and is composed of a plurality of annular cooling water pipes. Through the water-cooled heat storage combustor, body temperature of the bottom of the combustor and the fire outlet pipeline can be effectively reduced, and the service life of the combustor can be prolonged.
Description
technical field [0001] The invention relates to the technical field of burners, in particular to a water-cooled heat storage burner. Background technique [0002] At present, steelmaking plants mostly use direct-fired ladle roasters, self-preheating ladle roasters and regenerative ladle roasters to heat and roast ladles. Among them, the regenerative ladle roaster can make the ladle roasting temperature reach above 1100°C, which is beneficial to improve the internal quality of the billet and has significant economic benefits. The regenerative ladle baker adopts a high-frequency reversing valve, so that the high-temperature exhaust gas, combustion-supporting air and gas pass through the ceramic regenerator alternately, and conduct sufficient heat exchange with each other, so that the temperature of the combustion-supporting air reaches about 900°C, increasing the temperature of the combustion-supporting air. Its enthalpy can achieve stable combustion and achieve the purpose o...
