Single heat-storing nozzle device

Abstract

The invention relates to a single heat-storing nozzle device and belongs to the technical field of workpiece heating, heat treatment and burning. The single heat-storing nozzle device comprises a heat storage tank, a heat storage, a coal gas nozzle and a nozzle brick, wherein the heat storage is arranged in the heat storage tank and is used for storing heat; the coal gas nozzle is embedded between lug type air channels of the heat storage tank; the nozzle brick is connected with a channel of an external lug type heat storage tank; the heat storage tank is externally hung on the exterior of a furnace wall; the heat storage tank is composed of a section bar and a steel plate; a refractory cast material and a refractory fiber are lined in the heat storage tank; the heat storage is made from a spherical refractory material; the spherical refractory material is a cordierite, high-aluminum or mullite high-temperature refractory material; the diameter is 10-20mm; a high-temperature section of the coal gas nozzle 3 in contact with the nozzle brick 4 is made from a silicon carbide tube; a low-temperature section is made from austenitic stainless steel; the nozzle brick 4 is made from one or two of high-aluminum and mullite high-temperature refractory materials; and the use temperature is at 1200-1600 DEG C. The single heat-storing nozzle device has the advantages of convenience in mounting and overhauling and capability of realizing efficient energy conservation and emission reduction.

Description

technical field [0001] The invention belongs to the technical field of workpiece heating and heat treatment combustion, and in particular relates to a single regenerative burner device. In particular, it relates to an external ear type, multi-stream, swirl type single regenerative burner device. Background technique [0002] Regenerative combustion technology is an energy-saving and environmentally friendly new technology with remarkable effects. It has been widely promoted and applied at home and abroad in recent years. [0003] Judging from the current application examples, the first application mode is mainly represented by the built-in regenerative heating furnace in the tunnel. This technology integrates the burner and the heating furnace, has built-in heat storage balls, and adopts the method of centralized reversing. It is characterized by a relatively simple structure and a small number of valves. According to relevant information and production practice, there ar...
