<p>PURPOSE:To remove bad smell and poisonous substances in exhaust gas effectively in a combustion device inducing air for combustion from outdoor or indoor and discharging exhaust gas to outdoor after heat-exchanging by providing oxidizing catalyzer at a proper position in an exhaust pipe. CONSTITUTION:When a switch 20 for combustion is closed and a coil 21 for an electromagnetic valve for fuel is magnetized, an electromagnetic valve, not shown in a diagram, is opened and the fuel is flown into a fuel pot chamber 2 through a fuel pipe 3, thereafter, is ignited by an igniting heater 18. At the same time, air is supplied into an air chamber 7 by a suction fan 10 through a air suction port 16 and a suction pipe 8, futher, is supplied into the fuel pot chamber 2 through feeding ports 17. Combustion gas is discharged to outdoor through a heat-exchanger 4, an exhaust pipe 5 and an inner pipe 6a for an exhaust tube 6, however, the combustion gas of low temperature is heated in this case by a heater 13 energized through a contact 24 closed just after the fuel is ignited and the combustion gas is discharged after bad smell and poisonous substances contained therein are removed effectively by the oxidizing catalyzer 12.</p> |
