PURPOSE:To prevent operating condition from getting dangerous even during operation by constituting a disposer in such a manner that at the windward side of an air supply port introducing air into a main body a detecting means for wind pressure is installed and a control means stopping the operation of the disposer by the signal from the detecting means. CONSTITUTION:Microwaves act on garbage 4a and heat it to begin to generate a large amount of combustible gas. When the concentration of the gas approaches a lower limit value for explosion, the garbage is ignited by an ignitor 2a which absorbs microwaves and is brought in red-heat condition. When an initial ignition phenomenon takes place, the high pressure combustion gas in a main body 1 passes through an air supply port 7 and overcomes the air blasting from an air supply blower 8 to flow backward into an air supply duct 7a. The combustion gas pushes back a shutter for wind pressure and pushes a limit switch 17 which is preset to operate at a fixed pressure or more to operate a detecting means 15 for wind pressure. By the signal from the means 15 a control means 18 sends a warning signal with a lamp for warning abnormal condition, etc. and also stops the operation of a treater.
