The present invention relates to a boiler using chaff, and more particularly to a chaff boiler for using rice husk husk as a heating material of the facility house.

Many alternative boilers, such as late-night electric boilers and wood boilers, are produced and sold in farms to relieve the burden of fuel costs.However, late-night electric boilers use electricity only during a short period of time at night, resulting in high electricity costs and insufficient heating. In fact, wood-fired boilers are depleting forests because they require large amounts of wood fuel.

In addition, fuel costs according to high oil prices are increasing in facility farms for growing special crops and farms for raising livestock.

As an object of the present invention is to provide a boiler using a common chaff as a raw material such as discarded in rural areas.

In order to achieve the purpose, it is configured as follows.

FIG. 1 is a sectional side view of the rice hull boiler, FIG. 2 is a sectional view of the front side, and FIG.

As shown, the space portion 4 for receiving the blowing wind from the blower (2) on the inner lower end of the body (3); Located in the space (4) and loads the chaff (A) introduced through the rice husk inlet (5), the chaff loading is formed with a number of blow holes (6) so that the blowing air introduced into the space (4) is passed through Part 7; It is connected to the power connecting means 11 which is located above the rice hull loading part 7 and is operated by the power generating part 10, and when the power generating part operates, the chaff 'ash' is pulled backward or forward to discharge the outlet 12 A discharge device (14) having a straw (13) for discharging it into the;

A combustion chamber 15 which is positioned above the rice hull loading part 7 and is filled with rice husk introduced from the rice husk inlet 5; A burner (16) installed on the sidewall of the body (3) for initially igniting the chaff charged in the combustion chamber (15); A heat exchanger (16) positioned above the combustion chamber (15) and heated by heat generated in the combustion chamber (15); Characterized in that it consists of a communication 17, the exhaust gas of the combustion chamber is discharged.

The discharge device 14 is supported on the body (3), but the push rod 13 for pushing or pulling the 'ash' on the chain conveyor 'two' chain is positioned horizontally, chaff loading portion 7 of the chain conveyor Located between the tracks, but is configured to support the push rod 13 located on the lower side as if supported by the lower end.

The chaff inlet 5 is connected to a chaff storage room (not shown) for storing or storing the chaff and the pipe (5 '), the chaff of the chaff storage room is sucked into the pipe (5') to be discharged to the combustion chamber (15). The broa 20 is characterized in that it is connected.

Example

Embodiment of the configuration as described above, first, the chaff storage chamber is filled with chaff inside the bottom of the pipe (5) via the broa 20 so that the chaff is injected into the combustion chamber 15 of the chaff boiler (1) Is connected.

Here, broaran is a device used to inhale and discharge toxic gas to an outside in an industrial site or to suck out small molecule particles to be discharged to the outside.

Therefore, when the control box is not shown, the control box operates the broa 20 by the current connected to the control box organically to inhale the chaff stored in the rice husk storage chamber, and the sucked rice husk A is discharged to the combustion chamber 15. do.

After the discharge, the burner 16 ignites the rice hull when it is stopped by the control set in advance and the burner 16 which is the next signal is ignited. Of course, the blower 2 is operated on the rice hull so that the ignition is smoothly performed.

If the path of the blowing wind is described here, when the blowing wind is discharged to the space portion 4, the blowing wind passes through several blowing holes 6 formed in the rice hull loading portion 7 via the space portion 4. Leads to

Accordingly, the chaff during combustion actively heats the heating water of the heat exchanger 16 located above the combustion chamber.

As described above, when the temperature of the heat exchanger and the combustion chamber is lowered below the set level, the broa 20 is operated to introduce chaff as a raw material, and at the same time, the blower () is operated to increase the temperature of the combustion chamber. .

Next, the process of withdrawing the ash from the combustion chamber will be described.

The chain conveyor which rotates with the chaff loading part 7 in between operates the chain conveyor by a preset time or by, for example, a temperature sensing ('burned' ashes have a lower temperature and thus sense a lower temperature). When the push rod 13 located in the chain conveyor was operated to push the ash to the outlet 12 formed in the body.

The ashes thus generated are among the high-grade composts preferred by facility house farmers.

Effect 1) is that it uses chaff as fuel as it is not easily decayed and cannot be used for composting.

Here, chaff does not rot even after several years. Therefore, it is not suitable for use as compost.

2) Since the chaff of the rice hull storage room is automatically supplied by using a broa, the rice hull boiler of this application can be used automatically like a conventional oil boiler, and it is convenient.

3) The ash of rice hull is a high quality compost preferred by farmers and can be guaranteed extra income.
