Description

Burner burning soild fuel

The present invention relates to a solid fuel combustion burner, and more particularly to a solid fuel combustion burner having three combustion chambers.

Generally, natural chemical fuels such as coal, oil, and gas are used as fuels. However, in recent years, depletion of chemical fuel is a big problem, and efforts to find alternative fuels continue.

In the case of a burner that also needs fuel as a heating device, a burner for recycling waste that can be used as fuel has been developed, focusing on waste disposal, which has been suggested as a social problem while replacing natural chemical fuel. .

As the fuel of the burner, a solid fuel obtained by processing waste synthetic resins such as polyethylene (PE) or polypropylene (PP) is mainly used, because the heat generated during combustion is very high.

However, when the solid fuel using the waste synthetic resin is not completely burned, various harmful gases are generated during combustion, which may cause environmental problems such as air pollution, and are not good for worker's health. .

Accordingly, an object of the present invention is to provide a solid fuel combustion burner having a plurality of combustion chambers in order to solve the problems described above so as to completely burn the solid fuel made of waste synthetic resin so as not to generate harmful gases.

As shown, the solid fuel combustion burner of the present invention includes a first combustion chamber 10 for first burning solid fuel and a second combustion chamber for reburning the flame of solid fuel burned in the first combustion chamber 10. And a third combustion chamber 60 for finally burning the flame burned in the second combustion chamber 50.

FIG. 2 is a cross-sectional view showing the interior of the solid fuel combustion burner of the present invention composed of the first combustion chamber 10 and the second and third combustion chambers 50 and 60.

As shown in detail in FIG. 2, the first combustion chamber 10 ignites the net-shaped stack 12 on which the injected solid fuel 5 is loaded, and the solid fuel 5 loaded on the stack 12. Ignition means (14), a tray-shaped support plate (16) for supporting a solid fuel which is installed at the lower end of the loading portion (12) and ignited and melted, and placed on the support plate (16). A non-combustible fiber 18 to which the solid fuel melted at 12) is wetted, and a first blowing means 20 positioned between the loading part 12 and the support plate 16, wherein the inner wall is a fireproof wall. It consists of.

Here, the ignition means 14 functions to ignite the solid fuel 5 of the loading part 12, and at the same time, after the solid fuel is ignited, air may be injected as a blower to promote combustion. As the non-combustible fiber, asbestos may be mainly used.

In addition, the first combustion chamber 10 is provided with a solid fuel injection means 30.

The fuel injection means 30 includes an injection container 32 for temporarily storing the solid fuel 5a to be injected, an inner door 34 for injecting the solid fuel 5a into the combustion chamber 10, and the injection container. It consists of an outer door 36 for supplying fuel to 32.

In addition, the outer door 34 may be provided with an input lever 38 for pushing the solid fuel 5a of the input container 32 to inject fuel into the combustion chamber 10.
