Description

[0001] Inclination type air distribution apparatus, a fluidized bed combustion apparatus having the inclined type air distribution apparatus,

The present invention relates to an inclined air distribution apparatus, a fluidized bed combustion apparatus having the inclined air distribution apparatus, and a combustion method.

Generally, only combustible garbage is selected so as to have a calorific value of 3500 Kcal / kg or more among the wastes generated from various wastes, and it is made to be transported easily by molding if necessary, RDF (Refuse Derived Fuel).

Conventional combustion furnaces for burning such solidification raw materials are broadly classified into two types as described in Japanese Patent Laid-Open Nos. 1999-293264, 1997-159130, 1993-203133, and Japanese Patent No. JP 2775588 JP 2891996 One is to induce the circulation of the fluid in the reactor by varying the flow rate in the dispersion plate of the inner circulating fluidized bed, and the other is to form the partition plate in the circulating fluidized bed reactor to induce circulation of the fluidized bed. .

However, in the conventional combustion furnace which induces the circulation of the fluid in the reactor by varying the flow rate in the dispersion plate of the inner circulating fluidized bed, the inside of the reactor is not separated by the combustion part and the heat recovery, Since the circulation of the fluidized yarn is induced, the solidified fuel of the waste contained in the fluidized yarn interferes with the circulation of the fluidized yarn, resulting in a low circulation rate, a low heat recovery rate after the combustion, and a low efficiency of the combustion furnace.

In the conventional combustion furnace in which the partition plate is installed in the circulating fluidized bed reactor to induce the circulation of the fluidized bed, the solidified fuel, which is incompletely burnt while the fluidized bed and the solidified fuel are circulated together, is in direct contact with the heat- Thereby causing corrosion and wear of the heat transfer pipe.

In general, in the fluidized bed process, the air distribution system has a great influence on the mixing and abrasion of the solid and the gas, and the gas or air distribution apparatus is used by drilling a small hole in the plate or installing the nozzle. There is a drawback that a stable operation state can not be maintained due to reverse flow of water and corrosion caused by heat.

Further, in the fluidized bed process, stable and efficient combustion is achieved by active mixing of the solidified fuel and the fluidized air. However, in the form of the air distributor located in the existing combustion furnace, the active mixing of the solidified fuel and the fluidized air can not be performed. In particular, there is a need for an air distribution system capable of preventing the deposition of incombustibles that are entrained with solid fuel during solid fuel combustion in a fluidized bed combustion furnace and capable of simultaneous mixing of gaseous solids.

According to this necessity, Korean Patent Registration No. 1273312 discloses a fluidized bed combustion apparatus having a stepped air injector. Fig. 1 shows an overall constitutional sectional view of a fluidized bed combustion apparatus 1 having a conventional stepped air injector.

As shown in FIG. 1, a conventional fluidized bed combustion apparatus 1 having a stepped-type air injector has a structure in which a fluidizing material and a solidified fuel are contained therein and then a combustion operation is performed. And a discharge port 111 connected to the incombustible discharge portion 150 is formed at an inner center of the discharge port 110. The stepped structure is formed in a stepped shape having an air receiving portion 112 having a hollow space inside the stepped structure. A combustion furnace 110; An air supply unit 140 generating high temperature air heated from the outside of the step-like combustion furnace 110 and supplying the generated high-temperature air to the inside air receiving unit 112 of the step-like combustion furnace 110; Is connected through one side wall of the stepped combustion furnace (110) to discharge the high temperature air from the air receiving portion (112) to the inner space of the stepped combustion furnace (110) An air distribution nozzle 132 having a hollow pipe shape and vertically installed or bent so that its end is upward; An air nozzle cap (2) disposed at an end of the air distribution nozzle (132) and having a hexahedron shape and having a plurality of air discharge holes formed on a side surface and a lower surface thereof; And an incombustible discharge unit 150 for conveying and discharging the incombustibles discharged from the lower portion of the step-like combustion furnace 110 in one direction.

However, there is a problem that the air distribution apparatus having the conventional stepwise structure can not recover aluminum having low melting point among the non-combustible materials, and the bottom surface of each step of the stepped air dispersion plate has a length of 400 mm and 800 mm, There is a problem that it is difficult to effectively remove the nonflammable material at the low flow rate condition.

In addition, although the same number of air distribution nozzles are conventionally designed at each end of the stepped air distribution plate, it is difficult to prevent the channeling of the injection air because the differential pressure is increased by the height of the injected flow yarn at each end, There has been a problem that it is difficult to uniformly fluidize the material.

In addition, in the conventional stepped air dispersion plate, it is confirmed that the discharge of the nonflammable material is smooth under the condition of the fast fluidization bed, but the discharge of the nonflammable material is not smooth at the low flow rate of the bubbling fluidized bed condition. This is because the frictional force between the fluidized material and the nonflammable material is greatly reduced as compared with the circulating fluidized bed condition in the bubble fluidized bed operated at low speed. Therefore, there is a demand for a new structure of an air distribution apparatus which can overcome such a problem.
