Document Type and Number:
WIPO Patent Application WO/2019/044296
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide an oxygen-enriching burner and a heating method using the oxygen-enriching burner, wherein, when using a self-excited vibration flame to heat an object to be heated, the vibration period can be changed to an arbitrary vibration period, and the object to be heated can be uniformly heated at an excellent heat transfer efficiency. The present invention provides an oxygen-enriching burner characterized by being provided with: a central fluid jetting port (2) and a peripheral fluid jetting port (3) provided around the central fluid jetting port, wherein: a pair of openings (62a, 62b) are respectively provided in side walls (61, 61) of the fluid jetting flow passage (6) of the central fluid jetting port (2) at positions facing each other; the pair of openings (62a, 62b) communicate with each other through a communication part (7); the distance between a pair of side walls (63a, 63b) on the downstream side of the openings (62a, 62b) in the fluid jetting flow passage (6) gradually expands toward the downstream side; and the communication part (7) has a first communication pipe (71) and a second communication pipe (72) which have one ends (71a, 72b) respectively connected to the pair of openings (62a, 62b), and at least one or more communication elements (73) which are connected to the other ends (71b, 72b) of the first communication pipe (71) and the second communication pipe (72) and through which the first communication pipe (71) and the second communication pipe (72) communicate with each other.
