SUMMARY OF THE INVENTION The present invention relates to an incinerator having a combustion chamber formed inside a main body, and a chimney standing upright on the main body. Incineration characterized by providing a duct leading to the outside of the main body, opening the entrance of the duct toward the rear of the main body, and providing an opening / closing door that can be opened and closed on the side of the main body at the entrance of the duct. The above object is achieved by providing a furnace.

[0009]

According to the present invention, when the entrance of the duct is opened,
Outside air flows into the combustion chamber through the duct, thereby promoting combustion of waste material in the combustion chamber.

[0010] The entrance of the duct can be opened and closed by operating an opening / closing door provided therein, and
The amount of outside air that flows in can be adjusted by adjusting the opening of the door.

During the incineration process, when the opening and closing door is operated from the side of the incinerator main body and the opening thereof is increased, the amount of outside air flowing in increases, and the fire in the combustion chamber instantaneously increases. The flame is ejected from the entrance of the duct, and the ejected flame is directed toward the opening direction of the duct entrance, that is, toward the rear of the incinerator main body.

Therefore, there is no danger that the flame spouting from the duct entrance will hit the operator directly, and a safe incineration operation can be performed.
