To provide a catalyzer combuster in which a gas flow rate is made large and an air flow rate is made small on igniting and further, the gas flow rate is turned to a rated condition and the air flow rate is made large in a catalyzer combustion to improve the ignition performance and the combustion performance by interlocking an ignition part and a pressure adjusting part.
When a user pushes down an ignition switch 40a, as an ignition part 40 and a pressure adjusting part 38 are interlocked, a control valve is further opened owing to displacement of a control lever 60 and fuel gas ejecting from a fuel tank is increased. Further, the efficiency of an air ejector 25 is decreased and suction air volume is relatively decreased. Hence, flame touches a catalyzer 23 for combustion and temperature abruptly rises. When the user releases the ignition switch 40a, the control lever 60 transfers to the original position, and the gas flow rate returns to the rated value. In this way, the gas flow rate is increased and the air flow rate is decreased at the time of iginition, and the gas flow is returned to the rated condition at the time of catalyzer combustion in order to increase the ignition performance and the combustion performance.
