<p>PROBLEM TO BE SOLVED: To solve the inconvenience that poor combustion is caused due to the shortage of oxygen, which results from the decrease in the oxygen concentration of a closed space, even in a construction in which the interior space, that is a combustion chamber performing catalytic combustion, is completely separated from the interior space that internally contains an intake port of combustion. SOLUTION: An intake part 9 forms an ejector with a nozzle part 10 that is connected with a fuel gas tank 7 and a diffuser 12, and it is constructed of an intake pipe 13 and an exhaust pipe 17, both of which are provided to communicate with outside air. Fuel is ejected by the nozzle part 10 at a high speed. The air that is necessary for combustion is sucked in by the ejector from the intake pipe 13 to a catalytic combustion part 14, and the combustion exhaust gas is exhausted from the exhaust pipe 17. Since both the intake pipe 13 and the exhaust pipe 17 communicate with outside air, outside air is constantly introduced to the catalytic combustion, so that the sufficient amount of oxygen can be constantly secured. Further, the ejector by the fuel gas is used, so there is an effect that allows its non powered state.</p> |
