BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a burner for a pellet boiler, which includes a wiper 20, a fuel input plate 2, a fuel input unit 6, a combustion plate 1, an air chamber 300, a blower 3, and an ignition torch ( 4) and the fire control air hole 11 and the fire guide air hole (10).

The fuel input plate 2 of the present invention is an inclined trapezoidal plate, and as shown in FIG. 1, an injection hole 60 is formed at an upper end thereof, and a wiper 20 is formed by linking in the middle to distribute fuel. .

As shown in FIG. 2, the trapezoidal shape of the fuel input plate 2 is to uniformly disperse the fuel injected into the input hole at the top thereof, and the wiper 20 formed at the stop part when the fuel is injected for the equal dispersion. To adjust it.

The wiper 20 may be driven even during fuel injection to disperse the fuel evenly. However, the wiper 20 may be a fixed guide for adjusting the dispersing path of the injected fuel.

The fuel injector 6 of the present invention is a device for injecting the pellet-type solid fuel 7 into the inlet 60 of the fuel inlet plate 2. The fuel input plate is formed to be inclined on the support plate as shown in FIG. 1 so that the pellet-type solid fuel 7 introduced into the inlet 60 falls downward, and is also guided to the inlet 60. Walls are provided to protect pelleted solid fuel from spilling out.

In the present invention, the pellet-type solid fuel 7 is composed of sawdust as the main material.

Pellet-type solid fuels based on sawdust are also known as 'wood pellets'. Wood pellets are natural fuels made of cylindrical products by crushing wood by-products into sawdust and then drying and compressing them.

Wood pellets used in the present invention is not only to cut the wood deliberately but to recycle the forest by-products that are discarded as waste, so it is not only effective in reducing waste, but also completely burned and high in energy efficiency. Only about 12, it is regarded as environmentally friendly energy.

As shown in FIG. 4, the fuel injector 6 of the present invention includes a reservoir 63 for storing such pellet-type solid fuel 7 and a conveyor 62 for equally transferring fuel from the reservoir 63. It may be configured as an injection guide 61 for guiding the pellet-shaped solid fuel (7) connected to the conveyor (62) to the conveyor (62) to the inlet (60) of the fuel input plate (2).

The reservoir 63 preferably has a hopper structure as shown in FIG. 4 to facilitate storage and discharge of the pelletized solid fuel 7, and the conveyor 62 has a rotary screw transfer pump formed therein. It is preferable to use this to control the input amount of fuel in accordance with the rotational speed.

This makes it possible to control the dosage of the pelletized solid fuel 7 according to the combustion speed of the pelletized solid fuel 7, which is a necessary part for the complete combustion of the pelletized solid fuel 7.

The input guide 61 is a portion connecting the conveyor 62 and the inlet port 60 of the fuel input plate 2, and may be referred to as an extension of the conveyor 62.

In the present invention, the outlet of the conveyor 62 of the fuel injector 6 is formed vertically higher than the inlet 60, and the inlet guide 61 is inclined so that the pellet-type solid fuel 7 is inlet 60. Installed so as to fall).

The combustion plate 1 of the present invention is coupled to the lower end of the fuel input plate 2 in a continuous slope, as shown in FIG. And to concentrate on the goal.

The combustion plate 1 is a part in which the dropped pellet solid fuel 7 is burned, and devices for complete combustion of the pellet solid fuel 7 are provided.

The air chamber 300 of the present invention shown in FIG. 3 is formed as part of the device, coupled to the bottom of the combustion plate 1. Blower 3 is connected to the air chamber 300 from the outside to inject air, and the air chamber 300 and the combustion plate 1 have a fire control air hole 11 and a fire guide air hole 10 ) Are communicated with each other.

Accordingly, the air introduced from the blower 3 to the outside is distributed in the air chamber 300 and injected into the combustion plate 1 through the fire control air hole 11 and the fire guide air hole 10. .

The fire control air hole 11 is formed at both ends of the bone outer side of the combustion plate 1 so that the air injected into the air chamber 300 is collected into the pellet-shaped solid fuel 7 in the bone of the combustion plate 1 Guide to spray on.

The fire control air hole 11 may be formed by puncturing the combustion plate 1 toward the pellet-type solid fuel 7 as shown in FIG. 2, but in the present invention, the directivity of the air is further improved. As shown in FIG. 3, an incision surface communicating with the air chamber 300 is formed in the combustion plate 1, and the first slate 110 is installed parallel to the incision surface like a blender. An air hole 11 for adjusting the fire is formed.

According to this structure, the injection angle of the air toward the valley of the combustion plate 1 can be adjusted more directionally at the installation angle of the first slate 110.

The fire guide air hole 10 of the present invention is formed in a coupling portion with the fuel input plate 2 corresponding to a relatively upper end of the combustion plate 1 so that the fire generated in the combustion plate 1 is fired. Guide them to the firebox.

The fire guide air hole 10 also cuts a portion of the combustion plate 1 coupled to the fuel input plate 2 like the fire control air hole 11 and couples the second slate 100 to the top of the cutout. In this case, the guide angle of the firearm can be adjusted more directionally by the coupling angle of the second slate 100.

The ignition torch 4 of the present invention is formed in the valley of the combustion plate 1 to ignite the pellet-shaped solid fuel 7 collected by dropping in the valley.

According to the present invention configured as described above, the fuel input amount linked with the combustion speed is controlled by the fuel injector 6, and the injected fuel is evenly distributed in the valleys of the combustion plate 1.

In addition, the fuel ignited by the ignition torch 4 is controlled by the combustion speed and the thermal power by the air injected from the air chamber 300 to the fire control air hole (11).

Therefore, the fuel input amount of the fuel injector 6 and the driving speed of the blower 3 for injecting the air can be interlocked so that the maximum efficiency is generated.

On the other hand, due to the fire guide air hole 10, the combustion heat is faithfully guided to the boiler firebox to further increase the thermal efficiency.

It will be apparent to those skilled in the art that the present invention may be embodied in many other specific forms without departing from the spirit or essential characteristics thereof.

Therefore, the present invention is not limited to the above-described embodiments, and various changes can be made by any person having ordinary skill in the art without departing from the gist of the present invention as claimed in the following claims. It will be said that the technical spirit of this invention is to the extent possible.
