Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a heating device that uses both a solid carbonized material such as charcoal and a solid carbonized material such as firewood as fuel.

Currently, heavy fuel oil, liquid fuels such as kerosene, and gaseous fuels such as town gas and natural gas are used for heating.

Furthermore, electrical energy is generally used, and solid carbonized materials or solid carbonized materials such as coal, charcoal, firewood, waste paper, straw, and other solid fuels are hardly used. This is based on the fact that these solid fuels have nine various drawbacks, such as being troublesome to ignite, emitting a large amount of smoke during combustion, and requiring ash treatment after combustion.

However, for most of the liquid or gaseous fuels mentioned above, the raw materials must be imported from overseas, and from the standpoint of resource conservation, one option is to use solid fuels that are available nearby, especially firewood, Wood chips.

It would be advantageous if waste paper or the like could be used for heating purposes without having to suffer from the drawbacks mentioned above.

This invention was made based on the viewpoint of resource saving, and uses both a solid carbonized material and a solid carbonized material, and uses the combustible gas generated from the solid carbonized material as the main heat source in the device. The solid material to be carbonized is carbonized at the same time as the combustion is completed without producing smoke and the heat residue necessary for heating is generated.

Furthermore, it is an object of the present invention to provide an economical heating device that can reuse the carbide as fuel.

On the outer periphery of the upper furnace body (7), there is, for example, a wind pipe part m, which is formed into a semicircular shape and has both ends sealed.
It is fixed to the cylindrical body (13) via a distribution pipe (161 and a support part 1 having a rectifying part at the tip).

A member (stone) is attached to the 44 air passage section I23) facing the supporting section C6, which is connected to a hose connected to a small blower (not shown). The distribution pipe +] fi; has a radially protruding end with a port IJ ([jsa)] and a pipe part C.
ζ is the circular opening corresponding to the middle and b of the heart and wind canal)
As shown in FIG. 1, the furnace body (71) is connected to the conduit pipe section (23) so as to be slightly below the water buffalo in the 4H direction.

The distribution pipe (Iri') is equipped with six wind nozzles +271 shown in the perspective view of Fig. 3 so as to be rotatable. A semicircular blind lid is attached to the protruding distal end, and a rectangular air outlet pancreas is provided in the tube connected to it. Fixed, this supporting member Q! A rotating shaft (7) is attached to the rotating shaft (7) in the direction of the tube axis, and a spring receiver +3n is attached to the rotating shaft (7).
l:i: A compression coil spring G21 and an operating lever are respectively attached.

Therefore, in order to rotatably attach 1 to the distribution pipe (161) on this air guide nozzle, the end of the rotation axis 1. Insert the coil spring (:) into the distribution "a'flRl" from inside the furnace so that it is inserted into the through hole drilled in the center of the blind lid of the pipe (16), and then push it in while compressing the force, and then close the blind lid. Fit the operating lever C33) into the end of the rotating shaft 13Ql that protrudes from the shaft, and drive the dowel pin once so that the axis of the lever (33) and the blowout line 1-1QII are located within the same line -rMj. All you have to do is fix the moving axis smoothly.

In this way, the air introduction device i't 16+ connects the air blower to the connecting member connected via the hose to the pair of distribution pipes connected to it. (161) and a 4j lice nozzle (2) which is rotatably held and whose direction of air blowing into the furnace can be adjusted by operating an operating lever t331 from the outside.

The eye bolt 1 is rotatably attached to a fork-shaped bracket (34I) fixed to the mantle part ti11, and is provided so as to protrude in the radial direction from the flange part +81.191. After inserting the eye bolt 1 into the fork-shaped portion, the thumb screw G161 is tightened to connect the flange portions +81 to +91.

Next, the 11 cells and the charcoal making function in this device will be explained.

Loosen the thumb screw ()i) of the connecting member 1101, rotate the eye bolt (351) outward, and attach the flange part +81 +

Take out the heating combustion cylinder (5) from the upper furnace body (7), and put sufficiently ignited charcoal (4) inside it to a depth of about 7 in the wire mesh T2+1 container. (Fill 41 into a wire mesh (4) container until it is full.)

The heating combustion cylinder (5) filled with charcoal (4) in this way is installed again in the upper furnace body (7) as shown in the figure.

Next, turn the distribution pipe (operating lever 161) approximately 90° clockwise toward it.

In this case, the operating lever) is a 1 compression coil spring + 32)

is retained as is.

On the other hand, the connecting member t25) is connected to the small blower via a hose.
The air is sent through the air pipe section.

The rectifying part of the support member +24) divides the inside of the hydrangea part into left and right parts as shown by the arrows in Fig. 2, and flows through the opening part (5)) into the distribution pipe (16) as shown by the arrow. Each flows in as shown.

By the way, the air guide nozzle surfaces that are rotatably engaged with the distribution pipe (161) are rotated according to the rotation angle position of the operating lever +331 described above, so that the air blowing from the air guide nozzle surface is The mark is also oriented clockwise when viewed from above.Therefore, the air blown into the upper furnace body (7) from the outlet on the air guide nozzle surface is heated while gently swirling clockwise inside the furnace. In the combustion tube (5), the charcoal (4) is sucked into the rising air generated by the heat generated by the large charcoal (4), and oxygen is supplied abundantly to the charcoal (4). ignition of
The oxidation reaction of the charcoal (4) rapidly progresses and it becomes a bright red-hot state, that is, a high temperature state near t,ooo'C,

The heat shield plate (2) is attached to the filled firewood (1).
The wire mesh t2 is directly transmitted from the ilJx hole.
The lower part of the 1+ container becomes red-hot 1^9 due to Buddha heart fever.

As a result, the firewood (1) is heated rapidly from the upper part due to radiation heat transfer, and thermal decomposition starts from the part where the temperature is raised inside and outside 400'Q. minute +1
When combustible wood scum, which is a 1f soil material, rises from the lower furnace body (31) and comes into contact with the red heat of the heating combustion tube (5) and the lower part of the metal mesh (Z11 container), the air flow reacts with the oxygen supplied by the gas and starts flaming combustion.

The combustion then shifts to diffusion flame combustion.

When a flaming combustion like this starts.

Charcoal (4) The charcoal (4) is not sufficiently supplied with oxygen, and the charcoal (1) begins to flow from its surface to the inside.
419) Flameless combustion progresses slowly.

On the other hand, for 1111, the above-mentioned flame combustion of the flammable wood gas and subsequent diffusion flame combustion cause high temperatures to be released from the lower part of the heating cylinder (5) and the entire surrounding area.
l For example, 1,1 (about 10'c) (heat is transferred i

Heat to around °C. Therefore, the bucket-shaped container (2
) has become similar to a retort in which carbonization takes place, and the wood pile is also heated by heat conduction from its surface to the inside. In this way, the firewood (1) is heated to 500'C.

As the area where combustible wood gas is generated moves downward, carbonization gradually becomes impossible starting from the upper end.

This state will occur approximately 40 minutes after attaching the heating combustion tube (5) to the upper furnace body (7). f:

Ii/I, blow out the air from the air nozzle's air outlet (from the sword) through the small through hole in the periphery of the heat shield's former 21' and blow into the bucket-shaped container (inside 21') of the wood gas.

The reflected heat from the firewood (1) is also effectively transferred to the lower part of the firewood (1), resulting in the generation of combustible wood scum, which gradually causes carbonization to occur below the firewood (1). proceed towards.

Firewood 11.1.1 liters of firewood generates a considerable amount of tar as a result of the generation of wood gas, but it does not burn in a bucket shape (2).
Since the humidity within 1 cannot be maintained at around 5 (01'C), the +iiJ section cannot be converted into a substance, and furthermore, the 4i section is converted into combustible gas due to thermal decomposition. It can be effectively used as a deterrent, just like flammable wood gas.

Ru.

As mentioned above, the flameless combustion of the charcoal (4) that was filled in Kasen's Yakisho (51) progresses slowly, and the charcoal (4) burns out sequentially, so it is better to carry out Urashakin. However, during this time, I was exposed to the above-mentioned high i'1'li! produced by the above-mentioned flame firing.

Therefore, charcoal (41) does not cause incomplete combustion,
Its surface temperature is kept high enough.

Exhaust gas (even if the gas contains monoxide and 1 carbon.

While passing through the heating combustion tube (5), flaming combustion occurs.

At this time, heat is added to the exhaust gas.

Therefore, the flange of the heating combustion tube (5).

i Connecting the heat tube (not shown), the heat generated by exhaust gas and surplus air is high temperature, for example, about 300'C.
can be used for heating.

In addition, the exhaust gas does not contain carbon monoxide and almost no smoke-producing substances, but when heating a closed room, the exhaust gas flows into the outside air through the chimney connected to the teaching heat pipe. It is desirable to discharge it.

Since the temperature of the lower furnace body (3) is maintained at around 500°C while the flaming combustion of the firewood is being carried out, the tar content mentioned above is vaporized except for the remaining unburned components. When the firewood (1) burns, combustible gas is generated from the firewood (1), and the flaming combustion is completed, by slightly increasing the supplied air force 1, smoke generation can be suppressed.

Carbonization of firewood (1) takes a fairly short time (e.g. 8 hours)
Complete with .

Can be done.

This device is of a batch type in which the solid carbonized material (1) cannot be replenished during heating, but the hard 11* carbonized material (4) in the heating combustion tube (5)-\ cannot be replenished. Although possible and not shown in FIG. 9, a suitable charcoal press 4 may be installed on the side of the heating combustion tube (5).

For this reason, the lower furnace body (31) needs to have a capacity Lx that can perform heating by relaxing for at least 8 hours with the solid carbonized material (1) filled therein. Accordingly, the size of the upper furnace body (7) must also be determined.

For example, upper and lower furnace bodies +71. 2 flea inside f31

．． If you were there on July 1st on August 8th, you would have a room of about 10 tatami mats in size.
You can get 25 to 9 charcoal with the heating time frame.

It is also possible to simply use a heat-resistant material such as a stainless steel plate for the heat shield plate +21, but if you want to use heating as effectively as possible, it is better to use 111il fire insulation material.
