Combustion system of regenerative burner in continuous heating furnace

摘要

PROBLEM TO BE SOLVED: To provide a change-over combustion system capable of suitably heating a material in accordance with a furnace operation condition in a continuous heating furnace using a regenerative burner. SOLUTION: In the continuous heating furnace 1, a first control part for outputting a fixed control signal in order to execute the combustion control necessary to obtain a prescribed temp. in the furnace, a regenerative burner 11, etc., at one side of the furnace wall 10 and a regerative type burner 21, etc., opposed to the burner 11 at another side of the furnace wall 20 are combined with each other in accordance with the furnace operating condition to constitute plural pairs. Or the regenerative burners 11, 12, etc., at each of the furner walls 10, 20 are combined with each other to constitute plural pairs, and a second control part alternately changing over each pair of the regenerative burners into a combustion state and a heat recovery state based on the control signal from the first control part is provided.
