OSCILLATED COMBUSTION SUPPRESSING MECHANISM IN SINGLE END TYPE RADIANT TUBE DEVICE

摘要

PROBLEM TO BE SOLVED: To solve a problem that an oscillated combustion is apt to be generat ed in a stable manner, and when the oscillated combustion is generated once, not only noises are generated, but also a trouble such as an accidental fire is caused by the oscillation in a conventional single end type radiant tube device in which an inner tube with its end opened is concentrically disposed in an outer tube with an end closed, and an exhaust part is provided in the rear end side of the outer tube and a burner part is provided in the rear end side of the inner tube. ;SOLUTION: In the single end type radiant tube device, a pulsating combustion suppressing mechanism is proposed in which a pressure relief hole 10 or a clearance is formed in a part of the inner tube 2 corresponding to a position or near the position where the heat generation rate of a flame 11 formed by the burner part 5 is the highest.;COPYRIGHT: (C)2003,JPO
