PURPOSE:To keep a velocity of flow constant even when much fuel gas is available so that a source of fire is not extinguished, by constituting a combustion cylinder with an external and an internal cylinders and providing a flow control plate inside the internal cylinder. CONSTITUTION:A combustion cylinder 4 which burns fuel gas consists of an external cylinder 11 and an internal cylinder 12. A flow control plate 13 which is provided with a fixed hole 13a for standardization of a gas flow to a primary combustion chamber is provided in a body. Fuel gas which flows within the external cylinder 11 is mixed with air for primary combustion. The fuel gas is ignited and burnt reliably without having misfire by a device 15 of a source of fire as its flow is controlled with the flow control plate 13. The remainder of the fuel gas flowing within the internal cylinder 12 is heated and secondary combustion is carried out in the vicinity of a playing edge of the internal and the external cylinders. |
