Document Type and Number:
Japanese Patent JP6756683
Kind Code:
B2
Abstract:
An object of the present invention is to provide an oxygen-enriched burner which can change any oscillation period and uniformly heat an object to be heated with an excellent heat transfer efficiency when heating the object to be heated while moving the flame with self-induced oscillation, and a method for heating using an oxygen enriched burner, and the present invention provides an oxygen-enriched burner including a center fluid ejection outlet (2) and a peripheral fluid ejection outlet (3) provided around the center fluid ejection outlet (2), a pair of openings (62a, 62b) are provided at opposite positions on side walls (61, 61) of a fluid ejection flow path (6) of the center fluid ejection outlet (2), a pair of the openings (62a, 62b) are communicated with each other by a communication portion (7), an interval between a pair of side walls (63a, 63b) downstream of the openings (62a, 62b) in the fluid ejection flow path (6) is gradually expanded toward the downstream side, and the communication portion (7) includes a first communication pipe (71) and the second communication pipe (72) each having a first end (71a, 72a) connected to a pair of the openings (62a, 62b), and at least one communication element (73) connected to second ends (71b, 72b) of the first communication pipe (71) and the second communication pipe (72) and communicating the first communication pipe (71) and the second communication pipe (72).
