Abstract

The invention discloses a heat-storage-type burning device which comprises a furnace body, a burner block part, a furnace wall connecting member, a heat storage chamber, a combustible gas incoming pipe, an air-gas connecting body and an igniter. The burner block part comprises a burner block pouring material and a metal plate, an air nozzle and multiple combustible gas nozzles are arranged on the burner block pouring material, the combustible gas nozzles are arranged in a manner of surrounding the air nozzle, and the metal plate sleeves the burner block pouring material and is connected with the same through an anchoring hook. By the heat-storage-type burning device, reductive in-furnace atmosphere can be generated, and an in-furnace temperature field is more uniform, so that oxidation burning loss of the surface of a workpiece is reduced; uniformity of the in-furnace temperature field ensures integral balance uniformity in heating of the workpiece, so that quality of a heated workpiece is improved, and service life of the burner block part is prolonged. Due to porous and hierarchic burning, high-temperature oxygen-deficient burning can be realized, NOx concentration in the process of burning is lowered remarkably, oxidation burning loss of melting products is reduced, and energy conservation and environment protection are realized.

Description

technical field [0001] The invention relates to the technical field of fuel gas regenerative combustion, in particular to a regenerative combustion device used in heating furnaces and heat treatment furnaces in metallurgy, machinery and other industries. Background technique [0002] Regenerative combustion technology can achieve the ultimate recovery of flue gas waste heat. It has many advantages such as high efficiency, energy saving and low pollution emission. It can solve the contradiction between low production and high consumption in the thermal processing process. It is the most widely used energy-saving and environmental protection in industrial furnaces at this stage. Combustion technology, the development of this technology is also quite mature. Regenerative combustion technology is widely used in continuous industrial furnaces dominated by steady state, such as pusher type continuous steel rolling heating furnace and walking type continuous heating furnace. At pr...
