BURNER AND HEATING METHOD USING BURNER
Document Type and Number:
WIPO Patent Application WO/2019/044182
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a burner and a heating method, wherein, when an object to be heated is heated by a self-excited vibration flame, the discharged amount of NOx can be suppressed, and uniform heating can be performed at an excellent heat transfer efficiency even at a position far away from the burner. Provided is a burner 1 characterized by being provided with: a central fluid jetting port 2 having a fan-like cross-sectional shape in which the gap between a pair of side walls 63a, 63b gradually expands toward the downstream side; a pair of openings 62a, 62b which are provided in a side wall 61 of an upstream-side fluid jetting flow passage 6 of the central fluid jetting port 2 and communicate with each other via a communication pipe 7; a first peripheral fluid jetting port 3 disposed around the central fluid jetting port 2; a second peripheral fluid jetting port 4 disposed at a position where the distance between the center thereof and the center of the central fluid jetting port 2 is larger than the distance between the center of the first peripheral fluid jetting port 3 and the central fluid jetting port 2, and disposed in a direction perpendicular to the expansion direction of the central fluid jetting port 2; and a third peripheral fluid jetting port 5 disposed at a position where the distance between the center thereof and the center of the central fluid jetting port 2 is larger than the distance between the center of the second peripheral fluid jetting port 4 and the central fluid jetting port 2, and disposed in a direction perpendicular to the expansion direction of the central fluid jetting port 2.
