Traditionally, coal was used only for power generation and as a special fuel, but due to its widespread presence around the world and its abundance as a resource, coal is being reconsidered. Attempts are being made to develop technologies such as gas acids and liquefaction to make their use more convenient. Among the above, gasification technology uses coal, its dry distillation residue such as char and coke, and petroleum vacuum residue oil (heavy oil) alone or in a mixed state (
(hereinafter sometimes referred to as coal) used as a raw material,
This is then reacted with water vapor, oxygen or an oxygen-containing gas such as air, and a gasified gas to which hydrogen, etc. is added if necessary.
The content is to obtain a flammable gas whose main components are carbon monoxide and methane.

The gasification methods described above are classified into fluidized bed, fixed bed, spouted bed, and molten bed.Fixed bed was the main method in the past, but in recent years, due to the need for larger equipment and mass production, etc. A transition is being made to a suitable fluidized bed (bed) system. However, in the fluidized bed method, the ash particles generated during the gasification reaction adhere to each other or melt due to the softening of the particle surfaces in the high temperature atmosphere of the reaction itself, and generally have a specific diameter of 15 to 3. In some cases, it is easy to produce lumps with a diameter larger than that, and furthermore, these lumps may accumulate on the dispersion plate of the fluidized bed gasifier, on the equipment wall near the ash extraction pipe inlet, or on the walls of the equipment. This causes various problems such as destabilization of fluidized bed formation, difficulty in long-term and smooth reaction, reduction in reaction rate, and difficulty in extracting ash. There is a need for a continuous or intermittent ash removal method that also serves to prevent the accumulation and adhesion.

To further explain the subordinate extraction method described above, the first
The apparatus shown in FIGS. 1 to 3 shows an example of a fluidized bed gasification apparatus to which the above-mentioned gravity fall method is applied. A mixture consisting of coal and produced ash is fed into the lower part of the interior of the apparatus 1 under the supply of the gasification gas described below. a flat plate (see Figures 1 and 2) or a cone-shaped (see Figure 3) dispersion plate 2 for fluidizing the gas; and a line 4 for supplying gasification gas to the space below the dispersion slope. and an ash extracting pipe 3, and the ash extracting pipe 3 is connected to the device 1 in FIG.
vertically through the fluidized bed and the dispersion plate 2 in FIG. 2, and the dispersion plate 2 in FIG.
are provided vertically downward from the central opening.

Among the conventional devices with the above configuration, the devices shown in FIGS. 1 and 2 are easy to operate because they extract the ash particles floating on the fluidized bed by gravity, but on the other hand,
It is said that it is difficult to extract the ash lumps 5 that are generated directly above the dispersion plate 2, and that a relatively large amount of unreacted coal is entrained in the extracted material, resulting in a decrease in the casing reaction rate. There are drawbacks.

In addition, the device shown in Figure 3 is a system that extracts the ash-rich portion that settles in the fluidized bed by gravity, so it is easy to operate and can maintain a relatively high gasification reaction efficiency. However, the molten portion may aggregate and form a layer directly above the dispersion plate 2 and at the entrance of the extraction tube 3, and may even eventually block the extraction tube 3, making the fluidized bed formation unstable. However, disadvantages such as the inability to obtain a long-term and smooth reaction and the difficulty of extracting the ash are unavoidable.
