<p>PURPOSE:To enable to remove bad smell and/or poisonous substances from exhaust gas effectively in combustion devices of forced exhausting type or forced sucking and exhausting type by utilizing oxidizing catalyzer. CONSTITUTION:When a motor 12 is started and a suction fan 13 and an exhaust fan 14 are driven, air for combustion is sent into an air chamber 10 through a suction port 16 and a suction pipe 11, further, the air is supplied into a fuel pot chamber 2 and a combustion chamber 1 through feeding ports 17. On the other hand, when an electromagnetic valve 6 is opened at the same time, fuel is sent from a tank into the fuel pot chamber 2 through a fuel adjustor 4 and the electromagnetic valve 6, and thereby, combustions are effected in the pot chamber 2 and the combustion chamber 1. Then, combustion gas is flown into a exhaust pipe 8 through a heat- exchanger 7 and bad smell as well as poisonous substances are removed by oxidizing catalyzer 15 therein, thereafter, the combustion gas is discharged out of an exhaust tube 9. In this case, the oxidizing catalyzer 15 is provided in the exhaust pipe 8 located at a position between the outlet of the heat-exchanger 7 and the exhaust tube 9 where the temperature of the combustion gas is in a range in which removing rate of the catalyzer becomes comparatively higher.</p> |
