Abstract

This gas burner is provided with an injector 14 which, by injecting combustion air from a nozzle 14b towards the diffuser 14c, draws a gas into a diffuser 14c, and which discharges gas and combustion air from an exhaust port 14a into a fuel chamber 13. The amount of gas introduced into the combustion chamber 13 by the injector 14 varies depending on the amount of combustion gas supplied, so the amount of gas can be adjusted by means of the combustion air.

Abstract

In this gas generation device, a gas outlet tube 10 for guiding gas in a gas reservoir space S3 to outside of an outer wall tube 1 is configured from a gas inlet 11 which is arranged opposite of a top panel member 2, a straight tube portion 12 which hangs vertically downwards, and a curved tube portion 13 which is connected to the bottom of the straight tube portion 12; by arranging the gas inlet 11 in the gas reservoir space S3, arranging the straight tube portion 12 in a gasification space S1, connecting one end of the curved tube portion 13 to the straight tube portion 12, and arranging the other end of the curved tube portion 13 outside of the outer wall tube 1, it is possible to minimize adhesion of carbides such as carbon and tar to the inside of the gas outlet tube 10.
