The portable solid fuel combustion device of the present invention composed of the above components is assembled as shown in FIG. 2 by connecting the components as shown by arrows in FIG. 1 and used for use. At this time, the combustion furnace 1 housed in the mantle 2 is supported by the rod 12 projecting downward as shown in FIG. Is formed. In addition, a gap is formed between the combustion furnace 1 and the heat insulating and heat insulating layer 11 around the furnace, so that air required for combustion can flow from the gap.

Next, the use of the portable solid fuel combustion apparatus of the present invention assembled in this manner will be described.

First, the solid fuel in the combustion furnace 1 is ignited by activating an ignition means (not shown) provided in the combustion furnace 1 or by charging the ignited solid fuel or igniting material into the combustion furnace 1. I do. Then, the solid fuel held and held between the holding weight 11 and the tapered heat insulating material 9 around the holding weight 11 is supplied to the intake hole 10 a provided at the bottom of the combustion furnace 1.
And the air required for combustion are sequentially supplied from the intake gaps 8d and 8e provided in the surroundings, so that the combustion is started and continued without disappearing.

Then, the hot air generated by the combustion becomes an updraft and is led into the thermosensitive body 3 through the adapter 6. This heat sensitive body 3 is a metal plate having high thermal conductivity,
And, since it is formed in a tapered shape, the introduced hot air temporarily stays inside the thermosensitive element 3, is deprived of heat during that time, and is eventually exhausted to the outside through the chimney 4 communicating with the upper side. You. As a result, the surface of the thermosensitive element 3 is heated up to about 600 ° C. at the maximum, the temperature around the thermosensitive element 3 is raised, and the radiant heat is used for heating. is there.

Further, a thermosensitive element 3 is mounted on the upper end of the combustion furnace 1 upside down, and a net (not shown) or the like is placed on the upper part of the thermosensitive element 3. The device can also be used as a cooking appliance. In addition,
At this time, the chimney 4 is not attached, but the heat-sensitive element 3 attached on the upper side of the combustion furnace 1 acts to guide the high-temperature air accompanying the combustion upward, whereby the draft (ventilation) required for the combustion is produced. Is generated, fresh air is sequentially supplied to the combustion furnace 1, and a good combustion state is maintained.

The solid fuel used here may be lignite having an ash content of 5% or less, ogalite or petroleum coke having an ash content of less than 1%, and other similar coal pitch coke, molded coke, briquette, etc. Low ash solid fuel such as calcine coke. Therefore, the injected fuel is completely burned out without generating a residue, and the combustion is completed.

In the case of continuous use, the fitting of the adapter 6 (or 7) is appropriately released, the upper surface of the combustion furnace 1 is opened, and additional solid fuel is injected into the combustion furnace 1 from here. Just do it.

Further, when it becomes necessary to extinguish the fire during the combustion, the fitting between the combustion furnace 1 and the adapter 6 is released, and the upper surface of the mantle 2 is opened. Next, a separately prepared lid 5 (see FIG. 1) is fitted to the upper surface of the mantle 2. The lid 5 is provided with a heat insulating and heat insulating material 18 attached to the back surface, and the heat insulating and heat insulating material 18 is brought into close contact with the heat insulating and heat insulating material constituting the heat insulating and heat insulating layer 16 inside the mantle 2.
The inside of the mantle 2 is hermetically sealed. Therefore, the supply of air to the combustion furnace 1 is shut off, and the solid fuel in the combustion furnace 1 eventually extinguishes.

At the time of this fire extinguishing, the lid 5 covering the upper side of the combustion furnace 1 is provided with an adiabatic heat insulating material 18 on the back surface. However, the outside of the lid 5 does not become dangerously hot.

As described above, in the portable solid fuel combustion device of the present invention, the combustion can be forcibly interrupted during the combustion. Then, the respective parts located on the upper side of the mantle body 2 are disassembled completely reverse to the above-mentioned assembly, and as shown in FIG. 7, the cylinders 4a, 4b, 4c constituting the chimney are put together using the binding device 19, Is placed on the lid 5 fitted to the mantle 2, and the thermosensitive body 3 is covered from above as shown by the arrow,
Further, by placing the adapter 6 on the heat-sensitive body 3, the heat-sensitive body 3 can be made compact. Therefore, if the device is stored in the bag 20 as shown in FIG. 8 in this state, it becomes portable.

As described above, the portable solid fuel combustion apparatus of the present invention can be easily used in outdoor activities such as camping and fishing since the combustion can be easily interrupted during combustion and can be disassembled in a portable manner. is there.

In this way, the solid fuel that remains unburned even after the combustion has been interrupted once is completely burned out just like a normal low ash solid fuel by igniting again. Therefore, the use of the device can be resumed without any difference from the ordinary portable solid fuel combustion device.
