重油や廃油等の燃料油２０が収容される。The combustion device 4 is connected to the upper end opening 13 of the horizontal blow pipe 12 and the intermediate pipe 1.
The tip opening 15 of the oil feed pipe 14 inserted into the combustion chamber 1 is held upward in the upward opening 13, and the blower pipe 12 is connected to a blower 17 supported on a machine frame 16 on the outer surface of the combustion chamber 1. The oil feed pipe 14 is connected to an oil tank 1B supported above the combustion chamber 1 at the upper part of the blower 17 via a cock 19, and a fuel oil 20 such as heavy oil or waste oil is stored in the oil tank 18.

旋回空気供給装置５は上記送風管１２に設げた横向分岐
ノズルによって構成される。The swirling air supply device 5 is constituted by a horizontally branched nozzle provided in the blast pipe 12.

向突出部２′の内部に上昇する。Therefore, the garbage 31 is thrown onto the Rosdol 22, ignited and burned, and the cock 19 is opened to pour the fuel oil 20 into the oil pipe 1.
The air overflows from the tip opening 15 of the combustion chamber 1 and is blown by the blower 17 from the tip upward opening 13 of the blast pipe 12, and the air is also blown from the horizontal branch nozzle (device 5) to the combustion chamber 1. When swirled along the inner surface, the overflowing fuel oil is ignited by the combustion flame of the dust 31, and the fuel oil burns directly below the lower end opening 3 of the exhaust pipe 2, and the flame spreads to the downwardly protruding portion 2'. rise inside.

上記旋回空気は燃焼室１内の燃焼片その他の不純物を同
室１の内面に沿って下降させ旋回空気の中心部に上昇流
を発生しその上昇流によって上記燃料油は激しく燃焼す
る。The swirling air causes combustion particles and other impurities in the combustion chamber 1 to descend along the inner surface of the combustion chamber 1, generating an upward flow in the center of the swirling air, and the fuel oil is violently combusted by the upward flow.

そして上記旋回空気の上昇流は下向突出部２′によって

出部２１ま赤熱状態に加熱される。The upward flow of the swirling air is rectified by the downward protrusion 2', assisting the rise of the flame in the protrusion 2', and keeping the flame in a stable state. Combustion is assisted by the secondary air that enters from the protrusion 21, and the protrusion 21 is heated to a red-hot state.

又火焔は同突出部２′を経て上向突出部２“に上昇しそ

新鮮な３次空気によって燃焼はさらに促進されて残る未
燃焼ガスを完全燃焼させることができるものである。In addition, the flame rises to the upwardly protruding portion 2'' through the protruding portion 2', and combustion is further promoted by fresh tertiary air that enters from the vent hole 6 of the protruding portion 2 along with the upward force. It is capable of completely burning unburned gas.

得る便益がある。Conventionally, complete combustion of garbage has been extremely difficult, but since the present invention is constructed as described above, the combustion pieces of the garbage and other impurities are absorbed into the chamber together with the swirling air due to the air swirling inside the combustion chamber 1. The air swirls along the inner cylinder of the chamber 1 and descends to the rostrum 22 along the inner surface of the chamber 1 due to centrifugal force, and the air at the center of the swirl can generate an upward flow without containing any impurities. In step 4, the fuel oil is burnt significantly, and the flame is rectified inside the downward protrusion 1 of the exhaust pipe 2, resulting in an extremely stable flame due to the above-mentioned upward flow, and enters through the small ventilation hole 6 of the protrusion 2'. The combustion is assisted by the secondary air, which violently rises inside the upwardly protruding part 2'', and with the rising force, the small holes 6 to 3 of the protruding part 2''
Next air enters the exhaust stack 2 and can significantly promote combustion,
There is the advantage that complete combustion of unburned gas can be carried out very easily and quickly.

をきわめて確実化し得る特長がある。In addition, the downward protrusion 21 can extremely stabilize the rectification of the rising flame, and can be heated to a red-hot state by the flame, significantly promoting high-temperature combustion, thereby reducing the amount of unburned gas flowing into the upward protrusion 2''. It has the advantage that it can reduce the amount of combustion and ensure complete combustion in the protrusion 2''.
