JP-A-61-143608

By the way, in the above-mentioned conventional wood heating stove Sa, the lower wall 112 of the secondary chamber body R2 is heated to raise the temperature of the secondary combustion chamber R2, but the heating is performed only from the lower surface of the lower wall portion 112. Therefore, there is a problem that it cannot always be said that the heating efficiency is excellent.
This invention is made | formed in view of such a problem, and it aims at providing the soot stove which improved the heating efficiency in a secondary combustion chamber, and aimed at the improvement of combustion efficiency.

In order to achieve such an object, the soot stove of the present invention has an openable and closable soot inlet for introducing soot and an air inlet for introducing outside air to burn soot introduced from the soot inlet. A main body constituting a primary combustion chamber, a secondary chamber body constituting a secondary combustion chamber provided in the primary combustion chamber and combusting combustion gas flowing from the primary combustion chamber through an inlet, and the secondary combustion A chimney for exhausting the exhaust gas from the chamber, and a combustion promoting plate having a large number of small holes provided at the inlet of the secondary chamber body through which the combustion gas flowing from the primary combustion chamber into the secondary combustion chamber passes. In the wood stove
The secondary chamber body is formed of a metal plate having a cylindrical peripheral wall composed of a lower wall, both side walls, and an upper wall, and at least the lower wall and both side walls of the peripheral wall of the secondary chamber body are the primary wall. It is configured to be exposed in the combustion chamber.

Thereby, when burning soot, soot is thrown into a primary combustion chamber from a soot inlet and ignited. Since combustion air is supplied from the air port to the primary combustion chamber, soot burns in the primary combustion chamber, and as the combustion expands, the secondary chamber body is heated and the secondary combustion chamber becomes hot. The combustion gas reaches the secondary combustion chamber and further combustion proceeds, and the exhaust gas is exhausted from the chimney. In this case, the secondary chamber body is formed in a cylindrical shape, and at least the lower wall and both side walls of the peripheral wall are exposed in the primary combustion chamber, so that not only the lower wall but also both side walls are heated. Therefore, the heating efficiency in the secondary combustion chamber is improved and the combustion efficiency is improved as compared with the conventional case. In this case,
Combustion is promoted because the combustion promoting plate is red hot and the combustion gas comes into contact therewith.

  If necessary, the peripheral wall composed of the lower wall, both side walls, and the upper wall of the secondary chamber body is exposed in the primary combustion chamber. Thereby, since the upper wall is also exposed to the primary combustion chamber and heated, the heating efficiency in the secondary combustion chamber is further improved, and the combustion efficiency is improved.

In this case, if necessary, a space between the inner surface of the main body and the outer surface of the peripheral wall of the secondary chamber body is formed to a size that can accommodate the soot, and the soot inlet of the main body is used as the secondary chamber. It is effective that it is provided above the body and the air port of the main body is provided below the secondary chamber body.
Thus, when the soot is introduced from the soot inlet and the primary combustion chamber is filled, the soot is accommodated in the lower part, both sides and the upper part of the secondary chamber body. Since the cocoons are stored not only in the lower part of the secondary chamber body but also in both sides and the upper part of the secondary chamber body, it is possible to store extra cocoons, and the storage rate of the cocoon is extremely improved. . Moreover, since the air port of the main body is provided below the secondary chamber body, soot is mainly burned in the lower part of the secondary chamber body, and when combustion proceeds, it is on both sides of the secondary chamber body. The kite and the kite on the top gradually pass through the space on both sides and go down. Then, when the cocoon is lowered to both sides of the secondary chamber body, the cocoon is replenished. In this case, in the conventional stove, when a new soot is introduced, the new soot is placed on the burning soot, so that the combustion temporarily stops and the combustion becomes unstable. In the configuration, since new soot is put above the soot on both sides, the combustion of the soot burning below the secondary chamber body is not affected, and the combustion is stabilized. Can be made to do. Furthermore, the combustion gas in the primary combustion chamber reaches the upper part of the secondary chamber body, so that the soot here is heated, and when it descends and burns, it is heated. Combustion efficiency is easily improved in this respect as well.

  Further, if necessary, the main body is formed in a hollow shape including a bottom wall, both side walls, a top wall, a front wall, and a rear wall, and the axis of the secondary chamber body is along the longitudinal direction of the main body. Thus, it is set as the structure provided in the said primary combustion chamber. Since the soot can be stacked and stored in one direction so that the axial direction of the secondary chamber and the longitudinal direction of the soot are parallel to each other, it becomes easy to move the soot downward as the soot burns. Combustion can be stabilized.

  Further, if necessary, the upper wall of the secondary chamber body is provided with an inclined plate having a ridge line extending in the axial direction and having a mountain-shaped cross section inclined from the ridge line toward both side wall portions. When the soot moves with the combustion of the soot, the soot is distributed to the inclined plate and guided to the side of the secondary chamber body, so that the downward movement becomes smooth. Combustion can be stabilized.

  Furthermore, if necessary, the secondary chamber body is constructed between the front wall and the rear wall of the main body. Since the secondary chamber is installed, the strength is improved and the durability can be improved.

  Furthermore, it is set as the structure which formed the inflow port in the lower wall of the said secondary chamber body as needed. Since the inflow port is formed in the lower wall, the combustion gas can easily enter and the combustion efficiency is improved accordingly.

  Moreover, it is set as the structure which mounted the carbon fiber in the said combustion promotion board as needed. Since not only the combustion promoting plate but also the carbon fiber is heated and comes into contact with the combustion gas, the combustion efficiency is further improved.

  Furthermore, a container-like carbon fiber holding part configured to include the combustion promotion plate and hold the carbon fiber is provided at the inlet of the secondary chamber body as necessary. Since the carbon fiber is held in the carbon fiber holding portion, the carbon fiber is not easily moved by the flow of the combustion gas, and can be held securely and contribute to the combustion of the combustion gas.

  According to the present invention, the secondary chamber body is formed in a cylindrical shape, and at least the lower wall and both side walls of the peripheral wall are exposed and formed in the primary combustion chamber. Since it is heated, the heating efficiency in the secondary combustion chamber can be improved as compared with the conventional case, and the combustion efficiency can be improved. In addition, when the entire peripheral wall composed of the lower wall, both side walls, and the upper wall of the secondary chamber body is exposed in the primary combustion chamber, the upper wall is also exposed to the primary combustion chamber and heated. The heating efficiency in the secondary combustion chamber can be further improved, and the combustion efficiency can be improved.
