PROBLEM TO BE SOLVED: To improve practicability of a regenerative burner furnace.SOLUTION: A regenerative burner furnace includes (A) a pair of burners 20, and (B) a pair of heat storage mechanisms 40 provided correspondingly to the pair of burners 20, and each having (a) heat reservoirs 74, 76 and (b) an air supply/discharge passage 42. When combustion gas is discharged, the air supply/discharge passage 42 that each of the pair of heat storage mechanisms 40 has is formed so that the combustion gas flows downwardly, and at an exhaust lowering part 82 to be a place where the discharged combustion gas flows downwardly, at least a part 76 of the heat reservoir is provided. Since a residence time in the air supply/discharge passage is prolonged, and heat storage efficiency can be improved, practicability of the regenerative burner furnace is improved. |
