PURPOSE: To provide a catalyst combustion device capable of performing a stable combustion by a method wherein a gasification for restricting a flow rate of liquefied petroleum gas and gasifying it and an injector device for mixing the gasified gas with air and supplying them to a catalyst are provided, and a calorie of the catalyst is transmitted and supplied to the gasification part through a superior thermal conductor.
CONSTITUTION: Gas discharged from a nozzle 29 passes through a high expansion pipe 25 and a low expansion pipe 32 and is supplied to a catalyst 36 attached to the pipe 25. Combustion heat of the catalyst simultaneously heats the high expansion pipe 25 and the low expansion pipe 32. A surface of the pipe 32 abutting against the nozzle 29 moves in a direction away from the nozzle because of a difference of thermal expansion rate. The nozzle is biased by a spring 27, the valve 26 abuts against a nozzle base block 24 in compliance with a movement of the pipe 32 to shut off a supplying of gas. As a temperature of the catalyst 36 decreases, the supplying of gas is started again. With such an arrangement as above, the heat having expanded the high expansion pipe 25 is transmitted to the nozzle base block 24. The heat generated by gasification is removed by the nozzle base block 24 and the receiving fitting 23. This heat is supplied by the catalyst 36 and prevents a temperature of the nozzle base block 24 acting as the gasification part from being decreased.
