The wood-burning stove is desired to spread as an effective utilization measure of forest resources.

Utility model registration No. 3157839

Agricultural greenhouses are heated mainly by heavy oil stoves, but the profits have been under pressure due to soaring crude oil prices. A method of burning wood pellets is also being promoted as a cost reduction measure, but the cost of pellet processing is high. If you can use firewood as fuel as it is, it will be cheap, but there are problems to be solved.薪 When using fuel for heating greenhouses for agriculture, it is necessary to adjust the temperature. In addition, when a wood stove is used for heating an agricultural greenhouse, unattended operation of about 8 hours or more at night is required. As for a soot stove to be burned for a long time, a technology of utility model No. 3157839 has been proposed for the soot supply section. Utility Model No. 3157839 is a system in which a closed-type soot supply container is tilted to about 70 ° in front of the spout and a lid is attached to the top of the soot supply container to seal the soot supply container. Because of the method of opening the lid from the top of the bag and inserting the bag from above, the length of the bag is about 1.2 m due to the working conditions. When the length of the soot is 1.2 m, long-time combustion is difficult unless it is a thick soot with a diameter of about 150 mm to 200 mm. The utility model No. 3157839 requires a chimney of about 4 m in order to improve the suction conditions. Another technique is the wood-burning stove, commonly called the “rocket stove”. This technology was put into practical use in the United States in the 1980's, and is a system in which a vertical combustion chamber is surrounded by a heat insulating material, causing a strong upward combustion gas flow to generate strong suction. This rocket stove has a soot insertion port facing upwards, from which a stick-like soot is inserted and burned. However, it was difficult to ignite at the beginning, and it was unstable. In the initial stage, there was a lot of smoke generation, the combustion part was exposed, and there was a risk of fire.

The present invention basically solves the problem of temperature control by using a combination of a conventional heavy oil stove and a wood stove and using a wood stove as an auxiliary heat source for the heavy oil stove. The wood stove requires unattended continuous operation for about 8 hours or more at night. That is, a long vertical soot supply unit for charging soot that can be burned for about 8 hours or more is attached to the opening of the stove, and the soot inlet is sealed in the long vertical soot supply container at the time of combustion. A door is attached to the side surface so that it gradually burns from the bottom. Utility model registration No. 3157839, which is proposed as a publicly known example, is a method of attaching a lid on the upper side of the hook supply section, so the length of the hook is limited to about 1.2 m from the working conditions. According to the method of providing the door, the length of the ridge can be up to about 2.4 m, and the length of the ridge can be used up to about twice as long. With such a structure, it is possible to provide a soot stove capable of burning about twice as long as the conventional proposed technique. Furthermore, the combustion efficiency can be increased by attaching the following structure that enhances the suction effect by thermal expansion, commonly called “rocket stove”, to the above-mentioned sealed vertical long vertical soot supply container. . Combustion system commonly called “rocket stove” is a combustion system where the combustion gas in the lower heating part rises up at the combustion gas rising part partitioned by the heat insulating material, and then falls to the combustion gas descending part partitioned by the adjacent heat insulating part Then, it is a configuration sent to the heat radiating piping. This combustion method has good combustion efficiency and generates a small amount of smoke, and is commonly called a “rocket stove”, which was put into practical use in the United States in the 1980s. The so-called “rocket stove”, which has a strong suction by the combustion gas ascending part, is facing upward, and it is a method of burning by inserting a stick-shaped soot from here. It was stable and had a lot of smoke at the initial stage, and the combustion part was exposed, and there was a risk of fire. Unless this defect was improved, it was unsuitable for use in agricultural greenhouses. As a solution to this problem, a long vertical type and hermetically sealed type coffin supply unit for introducing the above type of coffin was provided. The basic structure of the so-called “rocket stove” is that the combustion gas rising part is surrounded by a heat insulating material. As a modification, a method in which the combustion gas descending portion is omitted can be used.

According to the configuration of the present invention, the soot inserted into the long vertical or closed soot supply section gradually burns from the lower part, and can be burned for a long time. The door attached to the side allows insertion of a soot approximately twice as long as the structure of utility model No. 3157839, which is the prior art, into the soot supply part, and even if the soot is thinner than the prior art, it will burn for a long time The practical range has been greatly expanded. The use of wood stoves is an important requirement for obtaining wood firewood, which has the effect of using a wide range of wood materials. In addition, the combustion system called “rocket stove”, which is equipped with a long vertical sealed soot supply section, has the effect of good combustion efficiency and low smoke due to the strong suction force. An experimental example has also been announced that a heat radiating section pipe of about 12 m in the lateral direction was possible due to the strong suction effect, and heat dissipation is easy. In this respect, it is very advantageous as compared with the structure of Utility Model No. 3157839 which requires an upright chimney of about 4 m. The inventive method has enabled continuous combustion for more than 8 hours. The problem of unstable ignition, the danger of fire and the generation of smoke in the so-called “rocket stove” could be solved. The so-called “rocket stove”, which is provided with a heated gas riser at the top of the heating section, is strong in suction and burnt material burns close to complete combustion, so that heat energy can be taken out with less soot. It generates little smoke and is suitable for agricultural greenhouses.

The present invention will be described with reference to the drawings. FIGS. 1 and 2 are a sectional view and a perspective view of an embodiment of the present invention. The cocoon supply unit 1 is a container for containing a cocoon that stands vertically with respect to a horizontal plane, and can be used to insert a long cocoon and is configured to have a height of about 2.5 m. The soot supply unit 1 may be inclined by 90 ° perpendicular to the chimney direction or 15 ° in the chimney direction with respect to the horizontal plane to prevent the soot from falling forward. On the other hand, if it is tilted in front of the air hole 2, the side of the soot throwing side becomes the chimney side, which hinders work. The lid supply unit 1 is provided with an upper lid 1-1 and a side door 1-2 for sealing. The side door 1-2 is locked by a lock 1-2-1. The side door 1-2 is sealed with an elastic material such as non-combustible ceramic. The side door 1 has an effect that it can be easily inserted from the side when a long material is inserted. The upper lid 1-1 has an effect that a short material can be introduced from above. The air port 2 and the lower air port 2-1 are attached. A heat-resistant glass window 1-3 for internal observation is attached. Soot burns from the lower part of the soot supply unit 1. The combustion gas is discharged from the combustion section 3 to the chimney 10. The chimney 10 is required to have a length of about 4 m from the suction conditions. The outer side is constituted by the outer shell A. 3 and 4 are sectional views of an embodiment in which the structure of the so-called “rocket stove” of the present invention is utilized and improved. The portion of the bowl supply unit 1 has the same configuration as in FIG. As the next stage of the combustion unit 3, the combustion gas raising unit 4 is provided, and the combustion gas that has become lighter at a high temperature rises from the combustion unit 3 to the combustion gas raising unit 4. The combustion gas rising part 4 is thermally insulated from the combustion gas falling part 6 by the heat insulating part 5. The heat insulating material 5 is made of a noncombustible material. As a result, the combustion gas pushed out from the combustion unit 3 descends to the combustion gas descending unit 6. Combustion gas is sent from the combustion gas descending portion 6 to the heat radiating portion piping 20. The outer side is constituted by the outer shell B.
