To solve the problems that disposal of waste is ununiform, incomplete disposal is generated and disposal efficiency is lower than an expected value in a process of waste disposal.
The waste disposal furnace is provided with an airtightly closed vessel 2 charged with the waste; a gas discharge passage 4 for discharging the generated gas in the airtightly closed vessel; an air feeding passage 3 for feeding a slight amount of air into the airtightly closed vessel; a pair of magnets 20 provided so as to clamp the air feeding passage and forming a magnetic field crossing the air feeding passage; and a flow rate adjustment means 18 provided on the midway of the air feeding passage and adjusting an amount of air fed into the airtightly closed vessel. A casing 19 formed by a non-magnetic body is provided on the midway of the air feeding passage and an air feeding passage formation hole 19a constituting a part of the air feeding passage is formed on the casing. A pair of magnets is arranged so as to clamp the air feeding passage formation hole and a throttle part 19c having a gradually narrowed downstream side is formed on the air feeding passage formation hole.
