Production device for industrial kiln

Abstract

The invention discloses a production device for an industrial kiln, and relates to a combustor. The production device is mainly composed of a heat exchanger, an air inlet pipe, a combustion chamber, amixer arranged in the combustion chamber and a main gun, wherein the heat exchanger is provided with an air runner and a smoke runner, the air inlet pipe is arranged on the heat exchanger and communicates with the air runner of the heat exchanger, the combustion chamber communicates with the air runner of the heat exchanger and the air inlet pipe, and the main gun communicates with the mixer andis used for gas conveying. The combustion chamber of the production device is of a cylinder cavity structure formed by a burner brick formed by combining a heat-resistant steel pipe framework and fireproof materials, the combustion chamber and the burner brick are of an integrated structure, and therefore the burning loss resisting capability of the combustion chamber can be greatly improved, andthe service life is prolonged; and through a through hole, the device ventilation effect is improved, and the service life of the device is prolonged.

Description

technical field [0001] The invention relates to a burner, in particular to a production device for an industrial kiln. Background technique [0002] Industrial kilns are equipment that enable products to complete a certain temperature curve, atmosphere curve, and pressure curve coupled processing. The kilns we discuss are limited to electric heating kilns, mainly kilns heated by resistance—resistance furnaces. Kilns are roughly divided into box type, well type, shuttle type, mesh belt type, rotary type, kiln car type, Push plate type tunnel resistance furnace, vacuum furnace, gas protection furnace, ultra-high temperature tube push plate furnace (carbon tube furnace), tungsten molybdenum powder roasting furnace, reduction furnace and other high, medium and low temperature industrial furnaces, working temperature 200~ 2500°C. Can be used for ZnO varistors, surge arrester valves, structural ceramics, textile ceramics, PTC&NTC thermistors, electronic ceramic filters, chip cap...

AI Technical Summary

Problems solved by technology

[0003] However, due to the addition of an independent heat exchanger on the burner of the self-preheating structure, the volume of the entire equipment is too large, and its installation is extremely inconvenient. Therefore, its heat transfer power is generally less than 1500KW. In some large-load industrial furnaces, it can only be solved by increasing the number of burners. Not only the investment cost is large, but also the heat transfer effect is poor. Therefore, we propose a production device for industrial kilns
