Claims (4)

  1. In a combustion zone installed at the lower part of the main body of a combustion device that burns combustible material, An air jacket that is horizontally installed at the lower part of the above combustion body and is formed in an elongated shape; A plurality of ribs horizontally installed at a spaced interval on the side of the air jacket along the longitudinal direction of the air jacket, forming an integral structure orthogonal to the air jacket, and having a combustible material accumulated on the upper part and combusted; and A ventilator that supplies outside air of the combustion body to the rib through the interior of the air jacket; The above ventilator is, An air chamber composed of a hollow space inside the air jacket formed along the longitudinal direction of the air jacket; A hole-shaped air supply port formed through one side of the air jacket in communication with the air chamber and communicating with the combustion body to supply outside air of the combustion body to the air chamber; and A combustion band for a combustion device comprising: a hole-shaped exhaust port formed through the side of the air jacket on which the rib is installed, facing the rib in a state of communication with the air chamber, and exhausting the outside air of the combustion device body, which flows into the air chamber through the supply port, to the rib in a state of opposition, thereby providing the outside air of the combustion device body to the combustion material combusted in the rib.
  2. In claim 1, the ventilator is, A combustion unit for a combustion device further comprising: a connecting pipe connected to the above-mentioned supply port in a connected state and penetrating the above-mentioned combustion device body to connect the above-mentioned supply port with the outside of the above-mentioned combustion device body.
  3. In claim 1, the air jacket is, A combustion plate for a combustion device, characterized in that one side equipped with the above-mentioned air supply port is rotatably fixed to the lower part of the combustion device body, and the other side is provided with a handle that is seated in a locking hole of the combustion device body to be locked or unlocked, and rotates around the one side by unlocking the handle.
  4. In Article 1, A combustion zone for a combustion device further comprising: an elongated external air guide formed along the longitudinal direction of the above rib and communicating with the above exhaust port to guide the external air of the above exhaust port or the above air chamber to the combustion material.

Description

Grating for combustion device The present invention relates to a combustion plate for a combustion device that burns a combustible material, and more specifically, to a combustion plate for a combustion device in which a combustible material is burned while stacked on top. Generally, boilers are used to supply heating and hot water in homes, offices, factories, and greenhouses. Oil and gas boilers are widely used due to their high thermal efficiency and ease of handling, as they leave no ash after combustion. However, using these boilers has presented economic difficulties due to rising fuel costs. In particular, rural areas, mountainous regions, and remote areas where conditions are unfavorable face not only economic issues stemming from increased fuel costs but also difficulties in installation and operation. Consequently, there is a growing trend of using stoves powered by various pellet fuels, including not only wood but also other biomass, primarily in general farms and factories for residential or small-scale commercial use. Such pellet stoves consist of a combustion section where pellets are loaded and generate combustion gases upon ignition, a chamber formed with a heating path to circulate the combustion gases generated from the combustion section, and an exhaust port connected to the chamber to exhaust the combustion gases to the outside. At this time, a pellet feeder is installed in the combustion section to supply pellets. Korean Utility Model Published No. 20-2024-0000068 (combustion plate for pellet combustion device) filed by the applicant of the present invention provides a pellet combustion plate installed at the lower part of a pellet combustion device body as shown in FIGS. 1 to 3, comprising: a fixed shaft portion installed to cross the body and having both ends fixed to the body; and a grating portion that is integrally connected to the fixed shaft portion, wherein a plurality of combustion zones are arranged spaced apart from each other along the fixed shaft portion and extend in the longitudinal direction intersecting the fixed shaft portion. This conventional technology can prevent the accumulation of ash generated after combustion, and since multiple plates are spaced apart from each other and manufactured as a single unit by joining with a fixed shaft, it can ensure structural stability by maintaining rigidity while simplifying manufacturing and assembly, and can improve combustion efficiency by securing an air passage to induce smooth air inflow and increasing the contact area with air. However, the applicant of the present invention has filed the present invention by improving the aforementioned prior art and developing a combustion chamber capable of supplying combustion air to pellets more smoothly. FIG. 1 is a schematic perspective view of a combustion device body according to the prior art. Figure 2 is a plan view of a combustion chamber installed at the bottom of the combustion chamber body shown in Figure 1. Figure 3 is a perspective view of the grating portion shown in Figure 2. FIG. 4 is a perspective view showing a part of a combustion device equipped with a combustion chamber according to an embodiment of the present invention. FIG. 5 is a perspective view of a combustion chamber installed at the bottom of the combustion chamber body shown in FIG. 4. FIG. 6 is a partially exploded perspective view showing a part of the combustion zone illustrated in FIG. 5. FIG. 7 is an exploded perspective view schematically illustrating the combustion zone illustrated in FIG. 5. Fig. 8 is a side view of the combustion zone illustrated in Fig. 5. Figure 9 is a cross-sectional view of the combustion zone shown in Figure 5. FIG. 10 is a perspective view illustrating another embodiment of the rib shown in FIG. 5. Hereinafter, a combustion device for a combustion unit according to an embodiment of the present invention will be described with reference to the attached drawings. A combustion chamber for a combustion device according to an embodiment of the present invention is installed at the bottom of the combustion device body (1) as shown in FIG. 4. As shown in FIG. 4, a combustion material, such as pellets, that is fed into the top of the combustion device body (1) is accumulated and burned in the combustion chamber (G). The combustion chamber (G) includes an air jacket (50), ribs (60), and a ventilator (70) as shown in FIGS. 5 to 7. As shown in FIGS. 5 and 8, the air jacket (50) is formed as a long housing or tube and is installed horizontally in a long manner at the bottom of the combustion body (1).
