Problems solved by technology

[0009] Therefore, in the regenerative burners shown in the above-mentioned publications, violent combustion occurs when the combustion is started in the regenerative burner in the heat storage operation, and the pressure in the heat storage furnace varies greatly. or incomplete combustion occurs, making it impossible to perform proper combustion stably
In particular, when a gas with poor combustibility, such as propane gas, is used as the fuel gas, black smoke (coal) is generated due to incomplete combustion, causing environmental problems, or coal adheres to the material to be treated, thereby Problems such as inability to heat treat properly

Embodiment Construction

[0040] Hereinafter, the combustion control method of the regenerative combustion type heat treatment furnace concerning embodiment of this invention is demonstrated concretely based on drawing. In addition, the combustion control method of the regenerative combustion type heat treatment furnace of the present invention is not limited to the method shown in the following embodiments, and can be implemented with appropriate changes within the range not changing the gist of the invention.

[0041] Here, in this embodiment, if figure 1 As shown, the material to be treated 1 made of steel that is guided from the entrance 11 of the regenerative combustion type heat treatment furnace 10 into the regenerative combustion type heat treatment furnace 10 is transported in the heat treatment furnace 10 by a walking beam 2 . The heat treatment is performed, and the processed material 1 thus heat-treated is taken out from the regenerative combustion type heat treatment furnace 10 through the...

Abstract

The invention provides a combustion control method of a regenerative-combustion heat treatment furnace, wherein during the alternated switching of the combustion orpeation and the regerative operation of a pair of regenerative burners, the strong combustion at the beginging of the combustion of the regerative burner operated in the regenerative action is inhibited. In the regenerative-combustion heat treatment furnace (10), a fixed amount of combtuion gas is supplied from a fuel gas supply device (30) to the fuel gas supply pipes (28a,28b) of the regenerative burners (20a,20b). During the alternated switching of the combustion orpeation and the regerative operation of the pair of regenerative burners, before the decreasing of the quantities of the fuel gas and the combustion air supplied by the fuel gas supply pipe (28a) and the air supply pipe (24a) in the regerative burner (20a) operated in the combustion action, the fuel gas and the combustion air supplied by the fuel gas supply pipe (28a) and the air supply pipe (24a) are supplied to the regerative burner (20b) operated in the regenerative action so as to start the combustion of the regerative burner (20b).

Description

[0001] related application [0002] This application claims the priority of Japanese Patent Application No. 2010-127570. technical field [0003] The present invention relates to a regenerative combustion type heat treatment furnace, and more particularly, to a combustion control method of the regenerative combustion type heat treatment furnace. Background technique [0004] Conventionally, when heat-treating a material to be processed, a regenerative combustion type heat treatment furnace is used, which is provided with at least one pair of regenerative burners having a combustion chamber including a fuel gas supply pipe part; a regenerator for storing heat storage material; an air supply pipe for supplying combustion air to the regenerator; and an exhaust gas discharge pipe for discharging combustion exhaust gas from the regenerator. In a regenerative burner, the combustion air The air supply pipe is guided to the combustion part through the regenerator, and the fuel gas ...
