Problems solved by technology

[0006] However, when removing deposits such as metals adhering to the air supply and exhaust ports in this way, there is a problem that it takes a very long time to stop the combustion of the regenerative burner and sufficiently lower the temperature in the heat treatment furnace. The efficiency is very low. In addition, it takes a long time to burn again to make the temperature in the heat treatment furnace high enough, and the productivity is greatly reduced.

Abstract

A heat treating furnace employing a regenerative burner, wherein the regenerative burner includes: a burning part configured to eject fuel from a fuel ejecting nozzle to burn; a regenerative chamber configured to accept regenerative material; and an exhaust path configured to discharge from the regenerative chamber to the heat treating furnace through an exhaust outlet, in the heat treating furnace, attachment attached to the exhaust outlet can be removed simply. In the regenerative burner (20) having the burning part (21), the regenerative chamber (22) and the exhaust path (23), a door (24) for maintenance is arranged on the exhaust path between the exhaust outlet and the regenerative chamber, the door for maintenance is opened and the attachment (X) attached to the exhaust outlet is cleaned by a cleaning component (30), wherein the burning part (21) is configured to make the fuel to be ejected from the fuel ejecting nozzle (210) to burn, the regenerative chamber (22) accepts regenerative material (220), and the exhaust path (23) discharges from the regenerative chamber to the heat treating furnace (10) through the exhaust outlet (230).

Description

technical field [0001] The present invention relates to a regenerative burner and a heat treatment furnace using the regenerative burner, wherein the regenerative burner includes: a combustion part that injects fuel from a fuel injection nozzle and burns it; The regenerator of the material; the air supply and exhaust passage that makes the combustion air be supplied to the heat treatment furnace from the supply and exhaust port through the regenerator, and the combustion exhaust gas in the heat treatment furnace is discharged from the supply and exhaust port through the regenerator. In particular, it is characterized in that when a metal such as aluminum is melted in a heat treatment furnace using a regenerative burner and a material to be treated is heat-treated, when metals such as aluminum and various impurities generated from the material to be processed are deposited When adhering to the supply and exhaust ports of the above-mentioned regenerative burner, such adhering su...
