Air inlet plugging convenient combustion furnace

Abstract

The invention relates to a combustion furnace achieving convenient air inlet leakage stopping. The combustion furnace achieving convenient air inlet leakage stopping comprises a furnace body. The furnace body is provided with a chimney, an air inlet and a gas fuel inlet. The air inlet comprises an upper section, a sealing piece and a lower section. The sealing piece comprise a rigid connecting tube, an upper rubber sealing gasket and a lower rubber sealing gasket, and the rigid connecting tube is sleeved with an upper clamping ring and a lower clamping ring. The upper end surface of the upperclamping ring abuts against the lower end surface of the upper rubber sealing gasket in a connection manner. The lower end surface of the lower clamping ring abuts against the upper end surface of thelower rubber sealing gasket in a connected manner. A plurality of lifting rods which are circumferentially distributed along the rigid connecting tube and drive the upper clamping ring and the lowerclamping ring to be separated in the vertical direction are arranged between the upper clamping ring and the lower clamping ring. The combustion furnace achieving convenient air inlet leakage stoppingaims to achieve the purpose that sealing can be online conducted when leakage happens to the air inlet and solves the problem that when leakage happens to an air inlet of an existing combustion furnace and leakage stopping is conducted, production interruption is needed.

Description

technical field

[0001] The invention relates to a furnace, in particular to a combustion furnace with convenient air inlet plugging. Background technique

[0002] Combustion of objects is usually done through a furnace, such as burning wood, coal, etc. Furnace combustion is accomplished by introducing air through the air inlet into contact with the substance to be burned (fuel) and then igniting it. The flue gas produced during combustion is discharged through the exhaust pipe. However, insufficient combustion often occurs during the combustion process, resulting in carbon monoxide contained in the tail gas being discharged along with the flue gas. The discharge of carbon monoxide not only wastes the fuel source but also causes air pollution caused by exhaust gas, and if it enters the room, it may cause carbon monoxide poisoning. In addition, the temperature of the tail gas discharged from the chimney is relatively high, and the temperature that the bag that removes dust ...
