- the gas discharge port 212b is formed in the vicinity of the front surface portion 216c of the upper surface portion 212.
- the gas discharge port 212b is connected to the fourth duct 146. Therefore, the gasified gas generated by the gasification furnace 140 is guided to the fourth duct 146 through the gas discharge port 212b.
- the raw material supply port 218a is formed on the back surface portion 216a.
- the raw material supply port 218a is provided above the fluidized bed R.
- the raw material supply port 218a is connected to the raw material supply pipe 134 of the raw material supply unit 130. Therefore, the raw material is supplied into the storage tank 210 through the raw material supply port 218a.
- the flow medium discharge port 218b is formed on the front surface portion 216c.
- the flow medium discharge port 218b is connected to the first duct 112. Therefore, the flow medium is guided to the first duct 112 through the flow medium discharge port 218b.
- the wind box 220 is connected below the storage tank 210.
- the wind box 220 has a rectangular tube shape having a rectangular horizontal cross section (XY cross sections in FIGS. 2 and 3).

- the fluidized gas supply unit 230 is, for example, a blower or a fan.
- the fluidized gas introduced into the air box 220 by the fluidized gas supply unit 230 is introduced into the accommodation tank 210 from the bottom surface portion 214 (dispersion plate) of the accommodation tank 210.
- the fluidized gas supply unit 230 introduces the fluidized gas into the air box 220 at a flow rate at which the fluidized bed R of the fluidized medium can be formed in the accommodating tank 210. Therefore, the high-temperature fluid medium supplied from the fluid medium supply port 212a is fluidized by the fluidized gas.
- a fluidized bed R for example, a bubble fluidized bed
- the flow medium is continuously supplied to the storage tank 210 from the flow medium supply port 212a (cyclone 120). Therefore, the flow medium supplied from the flow medium supply port 212a moves toward the flow medium discharge port 218b, then overflows (overflows) the flow medium discharge port 218b, and passes through the first duct 112 to the combustion furnace 110. Will be returned continuously. As a result, in the storage tank 210, the fluidized medium moves from the back surface portion 216a side to the front surface portion 216c side while forming the fluidized bed R.
- the raw material supplied into the storage tank 210 through the raw material supply port 218a moves from the back surface portion 216a side to the front surface portion 216c side along with the flow of the flow medium. Then, the raw material is gasified by the heat of the fluidized bed R (fluid medium) while moving in the storage tank 210. The gasified gas thus generated is guided to the purification device 150 (see FIG. 1) through the gas discharge port 212b and the fourth duct 146.
- raw materials such as coal and biomass have a lower mass density than fluid media such as silica sand. Therefore, when the raw material is supplied from the raw material supply port 218a formed above the fluidized bed R, the raw material falls on the surface layer of the fluidized bed R and moves along with the flow of the fluidized medium on the surface layer of the fluidized bed R. Will be done. That is, the raw material moves linearly in the horizontal direction (in the X-axis direction in FIG. 2) on the surface layer of the fluidized bed R without settling in the fluidized bed R, and is discharged from the fluidized medium discharge port 218b. As described above, when the raw material moves toward the flow medium discharge port 218b by the shortest route, the residence time of the raw material in the storage tank 210 becomes the shortest, and the gasification efficiency of the raw material cannot be improved.
- the flow medium supply port 212a of the gasification furnace 140 is formed on the back surface portion 216a side of the upper surface portion 212.
- the fluidized medium falls from the fluidized medium supply port 212a into the accommodating tank 210 (inside the fluidized bed R).
- the fluidized medium supply port 212a is designed to have a size that allows the dropped fluidized medium to slip into the fluidized bed R.
- the raw material falls from the fluidized medium supply port 212a, is accompanied by the flow of the fluidized medium (downward flow) that sneaks into the fluidized bed R, and sneaks into the fluidized bed R together with the fluidized bed.
- the gasification gas production apparatus 100 can avoid a situation in which the raw material moves only on the surface layer of the fluidized bed R in the horizontal direction. Therefore, the gasification gas production apparatus 100 can extend the residence time of the raw material and improve the gasification efficiency of the raw material.
- the flow medium supply port 212a is provided on the upper surface portion 212 at a predetermined distance from the side surface portions 216b and 216d. As a result, it is possible to avoid a situation in which the flow medium falling into the accommodating tank 210 through the flow medium supply port 212a comes into contact with the side surface portions 216b and 216d. Therefore, the gasification gas production apparatus 100 can prevent the side surface portions 216b and 216d from being worn by the flow medium.
- the flow medium supply port 212a is separated from the side surface portions 216b and 216d. Therefore, in the surface layer of the fluidized bed R, a gap is formed between the fluidized medium falling from the fluidized bed supply port 212a to the fluidized bed R and the side surface portions 216b and 216d. As shown by the solid arrow in FIG. 3, in this gap, the raw material moves on the surface layer of the fluidized bed R, but bypasses the place where the fluidized medium falls. Therefore, the gasification gas producing apparatus 100 extends the moving distance of the raw material as compared with the case where the raw material linearly moves on the surface layer of the flow medium from the raw material supply port 218a toward the front surface portion 216c. Can be done. As a result, the gasification gas production apparatus 100 can extend the residence time of the raw material.
- the gasification gas production apparatus 100 of the present embodiment can accompany the raw material to the flow (downward flow) of the fluidized medium and settle it in the fluidized bed R.
- the flow medium supply port 212a is brought too close to the back surface portion 216a, the flow medium comes into contact with the back surface portion 216a. Then, the back surface portion 216a may be worn, or the raw material supply port 218a formed on the back surface portion 216a may be blocked.
- the gasification furnace 140 of the present embodiment includes a guide unit 240.
- the guide portion 240 is provided with a water cooling mechanism, has a refractory lining, or is made of refractory bricks.
- the guide unit 240 includes a plate main body 242 (guide plate) and an upright plate 244.
- the plate body 242 is a plate that projects horizontally (in the XY direction in FIG. 2) into the storage tank 210 from vertically above the raw material supply port 218a on the back surface portion 216a.
- the base end of the plate body 242 is connected to the back surface portion 216a.
- the plate body 242 faces the flow medium supply port 212a. That is, a part of the projection surface of the flow medium supply port 212a is superimposed on the plate body 242. Therefore, at least a part of the flow medium that has fallen into the accommodation tank 210 through the flow medium supply port 212a falls toward the plate body 242 (guide portion 240).
- FIG. 4 is a perspective view of the guide unit 240.
- the erection plate 244 is a plate erected vertically above the edge of the plate body 242.
- the plate body 242 is a flat plate having a substantially rectangular shape. Therefore, three standing portions 244 are provided. Then, before the operation of the gasification gas production apparatus 100, the flow medium is held on the plate body 242. The upright plate 244 prevents the flow medium held on the plate body 242 from falling.
- a part of the fluidized medium that has fallen through the fluidized medium supply port 212a collides with the fluidized medium held on the plate body 242 and then falls to the fluidized bed R by its own weight.
- the gasification furnace 140 includes a guide unit 240.
- the guide unit 240 can change the drop locus (fall position) of the flow medium, and can direct the horizontal component of the downward flow of the flow medium toward the flow medium discharge port 218b.
- the guide portion 240 can secure a space for dropping the raw material on the surface layer of the fluidized bed R between the downward flow of the fluidized medium submerged in the fluidized bed R and the back surface portion 216a. .. Therefore, the guide unit 240 can avoid a situation in which the flow medium dropped from the flow medium supply port 212a comes into contact with the back surface portion 216a.
- the guide portion 240 can suppress the wear of the back surface portion 216a while causing the raw material to accompany the flow of the fluidized medium and settle in the fluidized bed R. Further, the guide portion 240 can avoid a situation in which the raw material supply port 218a formed on the back surface portion 216a is blocked.
- the flow medium is held on the guide portion 240 (plate body 242). Therefore, at least a part of the flow medium that has fallen into the accommodation tank 210 through the flow medium supply port 212a collides with the flow medium held by the guide portion 240. As a result, the gasification gas production apparatus 100 can suppress the wear of the guide portion 240 due to the dropped flow medium.
- the gasification gas producing apparatus 100 includes one cyclone 120 and a third duct 122 is taken as an example.
