つている。(Prior Art) A conventional spouted bed coal gasifier will be explained with reference to FIG. 6. Reference numeral 1 denotes an outer cylinder, and the outer cylinder 1 has a cylindrical upper part and an inverted conical lower part. An inner cylinder 2 and a nozzle 4 are provided on the upper part of the outer cylinder 1.
A slag reservoir 3 is provided at the bottom of the slag reservoir 3, and pulverized coal and gasifying agent are supplied from a nozzle 4 tangentially into the annular space between the outer cylinder 1 and the inner cylinder 2, and are swirled downward within the annular space. The pulverized coal becomes a flow and descends, and on the way, the pulverized coal is gasified, generating flammable gas, chir, and slag, and the large diameter slag moves toward the inner peripheral surface of the outer cylinder 1 due to the centrifugal force of the swirling flow. It scatters, then falls along the inner peripheral surface of the outer cylinder 1 and is collected in the slag reservoir 3. On the other hand, the small-diameter slag, combustible gas, and chir begin to rise at the inverted conical lower part of the outer cylinder 2 (see 7), and are discharged to the outside of the furnace through the inner cylinder 2.

た。(Problems to be Solved by the Invention) In the spouted bed coal gasifier shown in FIG. 6 above,
The nozzle 4 is a single-stage entrained bed type with one large diameter nozzle, which cannot handle low-load operation, and also has insufficient stirring and mixing of pulverized coal, resulting in low gasification efficiency. Furthermore, it is not possible to mix the char with the pulverized coal, and the char cannot be reused. In addition, the swirling flow between the pulverized coal and the gasifying agent ejected from the nozzle 4 spreads widely,
Since the pulverized coal particles collide with the inner peripheral surface of the outer cylinder 2, the inner peripheral surface of the outer cylinder 1 is damaged at an early stage. Further, the lower part of the inner cylinder 2 protrudes into the furnace under high temperature, and this part is damaged early, resulting in a problem of lack of reliability.

ス化炉を供する点にある。 The present invention deals with the above-mentioned problems, and involves comparing a plurality of pulverized coal supply nozzles and a plurality of chir supply nozzles alternately at predetermined interval positions in the circumferential direction of the furnace wall, and from the same positions centering on the core. A first-stage fuel supply section is provided in the tangential direction to a virtual circle with a small diameter, and swirls and raises the pulverized coal and chir supplied from each nozzle into the furnace together with the carrier gas, and a plurality of pulverized coal supply nozzles are connected to the furnace wall. The nozzles are provided in the furnace at predetermined intervals in the circumferential direction of the furnace in a direction in which the nozzles face each other or in a direction opposite to the swirling upward flow, and the pulverized coal supplied from each nozzle into the furnace together with the carrier gas is introduced into the swirling upward flow. and a second stage fuel supply section to collide with each other,
The present invention relates to an entrained bed coal gasifier characterized in that the second fuel supply section is provided above the first fuel supply section, and its purpose is to support low-load operation. Gasification efficiency can be improved. Not only can the char be mixed with pulverized coal, but the char can also be reused. Another object of the present invention is to provide an improved spouted bed coal gasifier that can further improve reliability.

In addition, the first stage fuel supply is provided from each position in a tangential direction to an imaginary circle of relatively small diameter centered on the reactor core, and swirls and raises the pulverized coal and chir that are supplied from each nozzle into the reactor together with the transport gas. and a plurality of pulverized coal supply nozzles are provided in the furnace at predetermined intervals in the circumferential direction of the furnace wall in a direction in which the nozzles face each other or in a direction opposite to the swirling upward flow, and the pulverized coal is transported from each nozzle into the furnace. and a second stage fuel supply section that causes the pulverized coal supplied together with the gas to collide with the swirling upward flow, and the second stage fuel supply section is provided above the first stage fuel supply section, and a large number of Any pulverized coal supply nozzle can be used to support low-load operation. Further, in the first stage fuel supply section, pulverized coal and chia are ejected from the plurality of pulverized coal supply nozzles and the plurality of chir supply nozzles in the tangential direction to form an upward swirling flow, and in the second stage fuel supply section,
Since the pulverized coal is ejected from the plurality of pulverized coal supply nozzles toward the upward swirling flow and collides with the upward swirling flow, stirring and mixing are promoted and gasification efficiency is improved. There is also a chir supply nozzle, which allows the chir to be mixed with the pulverized coal and allows for the recycling of the chir. In addition, each pulverized coal supply nozzle and each chir supply nozzle of the first stage fuel supply section are provided in the tangential direction to a relatively small diameter virtual circle centered on the reactor core, so that the tip of each noise is located at the same virtual circle position. Since it is open and an upward swirling flow is formed at a position within the furnace that is away from the furnace wall, damage to the furnace wall is prevented as much as possible, improving reliability.
