PROBLEM TO BE SOLVED: To ensure stabilized combustion by supplying secondary combustion air from the outside of a system and discharging exhaust gas after exchanging heat thereby recovering heat with high efficiency and making uniform the combustion air flow and exhaust gas flow. SOLUTION: Heat storage burners 16, 17 are disposed oppositely to the widthwise direction of a furnace and when the A side heat storage burner 16 is combusting and the B side heat storage burner 17 is storing heat, secondary combustion air is made to flow uniformly from an air supply/discharge pipe 5 to a low temperature space section 14 in the A side heat storage burner 16. The uniform flow is preheated at high temperature through a heat storage body 3 in a heat storage section 4 and made to flow uniformly again at a high temperature space section 13 before being jetted into the furnace through an air supply/discharge hole 12 in a baffle 10. On contrary to a conventional heat storage burner, high heat recovery is realized utilizing all heat storage bodies efficiently while eliminating temperature deviation of air being delivered from the air supply/discharge hole 12 for supplying secondary combustion air resulting in stabilized combustion. |
