Claims

[Scope of Claim for Utility Model Registration] (1) A combustion tube comprising an outer tube and a cylindrical inner tube provided inside the outer tube, forming a combustion chamber with one end open as a flame port, and this combustion tube. A fuel injection nozzle that faces the combustion chamber of the cylinder and ejects fuel toward the flame port, a combustion air introduction path formed between the outer cylinder and the inner cylinder, and the inner cylinder! a combustion air introduction means for introducing combustion air into the combustion chamber, which has a combustion air introduction hole drilled therein; and a combustion tube that protrudes along the inner periphery of the opening of the flame port of the combustion tube. What is claimed is: 1. A combustion device comprising: a constriction portion configured by plastically deforming a part of the inner cylinder, and a constriction portion for preventing discharge of unburned air-fuel mixture flowing along the wall surface of the inner cylinder. (2) The combustion device according to claim 1, which is a registered utility model, characterized in that an air introduction hole is provided at least in the vicinity of the throttle portion. , - - (3) The i-burning cylinder has a baffle in the combustion chamber, and this baffle holds the tip of the support member having a thermal expansion absorption part in a plurality of engagement holes formed in the peripheral wall of the baffle. Letting &
The combustion device according to claim 1, characterized in that it is supported by more than 1,000. (4) Claim 3 of the utility model registration, characterized in that the support member having the thermal expansion absorbing portion is made of a wire rod bent into a state having a curved portion in the middle. - Combustion device as described in clause.
