The combustion chamber 220 has a cylindrical upper portion, an inverted cone portion in the middle portion, and a cylindrical portion having a small diameter in the lower portion.

The fuel supply unit 280 is for discharging and supplying the particulate solid fuel in a spiral direction from the upper portion of the combustion chamber 220. The fuel supply blower 282 blows and moves the fuel to the combustion chamber 220 to discharge the solid fuel. And a fuel supply pipe 286 coupled to the combustion chamber 220 such that the solid fuel of the hopper 284 is discharged in a tangential direction inside the combustion chamber 220. The fuel supply unit 280 has a function of spirally discharging fuel into the combustion chamber 220 to facilitate combustion of solid fuel such as rice hulls, dry powder, and dry powder. That is, when the solid fuel is supplied from the hopper 284, the blower 282 discharges the fuel supplied into the combustion chamber 220 through the fuel supply pipe 286.

The air supply unit 240 is for supplying air (oxygen) necessary for combustion to the combustion chamber 220 when combustion of solid fuel is made in the combustion chamber 220, and combustion of fuel to the upper side and the lower side of the combustion chamber 220. It is to supply the necessary air.

Let's look at this more specifically.

The air supply unit 240 has a plurality of air supply holes 242 perforated on the lower inner wall of the combustion chamber 220, one side is connected to the air supply pipe 244 and the air supplied from the air supply pipe 244 is an air supply hole ( An air induction member 246 surrounding the lower sidewall of the combustion chamber 220 to be supplied into the combustion chamber 220 through the 242, and a blower 248 for supplying air to the air supply pipe 244. The air supply unit 240 has an air supply hole 242 formed in the entire inner circumference of the lower inner wall of the combustion chamber 220, so that the air supplied from the blower 248 is lowered from the combustion chamber 220 by the air induction member 246. It can be supplied at the same time in ° direction.

That is, the air supply hole 242 is formed in the entire lower wall of the cylindrical combustion chamber 220, the cylindrical air induction member 246 is installed to maintain a distance from the wall between the air induction member 246 and the wall. Since the space is formed, the air supplied by the blower 248 is supplied to the space formed by the air inducing member 246 and then supplied to the combustion chamber 220 through each air supply hole 242 in the 360 ° direction. It can be. This is to increase the combustion efficiency by allowing the air to be constantly supplied from all directions.

The air supply unit 240 further includes means for supplying air to the upper portion of the combustion chamber 220. That is, the air discharge member 243 is disposed directly above and below the central region inside the combustion chamber 220 and has a plurality of air discharge holes 241 perforated therein, and the air discharge member 243 has air. It has a structure connected to the blower 248 by the supply pipe 245.

Since the air discharge member 243 is vertically installed at the inner center of the combustion chamber 220, air is more efficiently supplied when the fuel is combusted in the combustion chamber 220, thereby increasing combustion efficiency. That is, since air is supplied to the inner center of the combustion chamber 220 where combustion of the fuel is directly performed, complete combustion of the fuel can be achieved, which means that the combustion efficiency is increased.

At this time, the blower 248 may be separately provided to supply air to the air induction member 246 or the air discharge member 243, but preferably to selectively supply air to both sides with one blower 248. It is desirable to.

To this end, the air supply unit 240 includes an air amount adjusting unit 247 for adjusting or selectively supplying the amount of air supplied to the air induction member 246 or the air discharge member 243. The air amount adjusting unit 247 may be respectively installed in the air supply pipe 244 connected to the air induction member 246 or the air supply pipe 245 connected to the air discharge member 243, and connected to the air induction member 246. It may be installed in the branched area of the air supply pipe 245 connected to the air supply pipe 244 and the air discharge member 243, may be provided only in any one supply pipe, it may be provided in the blower 248 itself. .

If the air amount adjusting unit 247 is provided in the air supply pipe 241, the air amount adjusting unit 247 may be configured as follows. That is, by installing a disk-shaped blocking plate in the air supply pipe 241, it may be configured to adjust the amount of air supplied by opening and closing the inside of the air supply pipe 241 by rotating the blocking plate.

In addition, the combustor 200 according to the present invention further includes a cyclone apparatus 500 for removing dust and the like contained in the exhaust gas discharged. The cyclone apparatus 500 is connected to the upper side of the combustion chamber 220 and the exhaust pipe to collect particulate matter contained in the exhaust gas, and the gas is discharged.

Referring to the operation of the ash discharge device 100, the combustor 200 and the boiler 400 according to another embodiment configured as described above are as follows.

First, fuel is supplied into the combustion chamber 220 to burn, and ash is generated in this process.

Then, when the rotating shaft 121 rotates by the operation of the drive member 130 by the timer, the lower side disk 118 rotates. Accordingly, the upper and lower ash discharge holes 112 and 116 intermittently coincide with each other. That is, since the lower side disk 118 rotates at a constant speed, the upper and lower ash discharge holes 112 and 116 intermittently coincide with each other.

As such, when the upper and lower ash discharge holes 112 and 116 coincide with each other, the ash collected in the lower portion of the combustion chamber 220 is discharged downward through the matched upper and lower ash discharge holes 112 and 116. At this time, since the lower ash discharge hole 116 is formed in a long hole shape, it is easy to discharge the ash passing through the circular upper ash discharge hole 112, and the upper and lower ash discharge holes 112 and 116 are easily matched. It is done. In addition, since the ash stirring member 124 located at the lowermost side stirs the ash, the ash can be easily discharged by being pushed to the upper ash discharge hole 112 side.

On the other hand, the drive member 130 operates the re-aggregation prevention unit 120 at a set time, and the upper and lower ash discharge holes 112 and 116 intermittently coincide with each other, so that fuel that is in progress or not yet burned is discharged. Phenomenon is prevented.

As the air is supplied to the lower and upper portions of the combustion chamber 220, combustion of solid fuel is smoothly performed to improve combustion efficiency, and the combustion is completed to prevent agglomeration and to discharge ashes intermittently. It is done efficiently.

And, the action of the hot water boiler 400 is the same as the above-described embodiment.

As described above, by combusting solid fuel, such as dry powder, dry powder, wood pellets, chaff, etc. to efficiently configure the boiler 400, not only energy can be saved, but also livestock manure generated in livestock farms, etc. By treating as fuel, it is possible to prevent environmental damage due to the disposal of livestock manure and at the same time to solve the heating of the winter house at low cost. In other words, by fueling the waste livestock manure and constructing a boiler using such fuel, it is possible to remarkably reduce the fuel cost required for heating and to protect the environment.
