[0003] However, in the conventional combustion type deodorizing apparatus, the refuse generated by the combustion of the exhaust gas in the combustion chamber falls down to the burner provided in the lower part of the combustion chamber and closes the hole of the fuel injection nozzle. Injection failure occurs, or a situation occurs in which ignition ignitability cannot be achieved due to combustion dust adhering to the ignition plug, and the exhaust gas cannot be efficiently burned.

Therefore, the diameter of the nozzle hole is increased so that combustion dust does not block the nozzle hole. However, when the diameter of the nozzle hole is increased, the amount of injected fuel increases, and the fuel becomes excessive. Therefore, the fuel consumption increases and the combustion efficiency deteriorates.

[0005] In order to reduce the probability of occurrence of ignition failure due to the adhesion of combustion dust to the spark plug, a measure is taken by providing a plurality of spark plugs. The attachment of the combustion dust cannot be prevented, and the provision of a plurality of spark plugs complicates the device structure of the combustion type deodorizing device and increases the cost of the device.

Further, when the conventional combustion type deodorizing device is used outdoors, there is also a disadvantage that rain enters inside through an exhaust window or the like, and the ignition portion at the tip of the spark plug gets wet with rain and causes poor ignition. Has occurred.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and efficiently deodorizes combustible odorous components in exhaust gas and reduces fuel consumption to improve combustion efficiency. It is an object of the present invention to provide an enhanced burner device and combustion type deodorizing device.
