摘要： PURPOSE:To obtain the uniform scattering property, by providing a rotor inlet chute part with a coal guide plate, and a rotor outlet discharging part with a scattering guide plate in such a way that the angles of both the guide plates can be varied. CONSTITUTION:In the inlet chute part 5 of a rotor 4 of the spreader stoker 3', the coal guide plate 6 is pivotaly attached to the top of a slant wall 5a, the tip of a handle shaft 7 threadably extending through the slant wall 5a abuts on the undersurface of the coal guide plate 6, and the angle of the coal guide plate 6 can be varied by rotating the handle shaft 7. In the outlet discharging part 8 of the rotor 4, the guide plate 9 for scattering coal extends through the side wall and is supported by a rotating shaft 10, one end of the rotating shaft 10 is provided with a handle with a stopper, and the angle of the scattering guide plate 9 can be varied by rotating the handle. Thus even if there is a change in the distribution or the like of particle size of coal supplied to the fluidized bed combustion furnace, uniform scattering property can be obtained.

摘要： PURPOSE:To enable quick repair of a choked oil feed pipe and to ensure operation of fluidized-bed boiler, by a method wherein a temperature sensor for continuously detecting temperature change in a pipe is located between the fuel injection port of a fuel feed pipe and a branch part. CONSTITUTION:Fuel is continuously fed in a fluidized-bed boiler 1 during operation of the fluidized-bed boiler. A large lump of particle coal is sometimes blocked at a fuel injection port, and if the fuel is not supplied, the temperature of a fluidized bed which the fuel injection port shares is reduced to cause occurrence of an obstacle, such as production of SOX, incomplete combustion. Since fuel flow is stopped due to blocking of a pipe, the fuel feed pipe 4 is gradually heated by the heat of a combustion chamber 2, and is increased in temperature as compared with other fuel feed pipe. Such temperature change is detected by a temperature sensor, and a boiler supervising attendant visually finds the choked pipe and is completed to repair it. In repair, a valve 10 of said feed pipe 4 is blocked and compressed air is introduced in the feed pipe 4 through a compressed air introducing port 11 to blow off the lump present at the blocked part.

摘要： PURPOSE:To obtain carbon black at a relatively low temperature by forming a jetting stream bed from seed nuclear particles and simultaneously regulating the temperature in the central part of the jetting stream bed within a specific range, blowing a hydrocarbon gas into the interior of the jetting stream bed, thermally decomposing and incompletely burning the hydrocarbon gas. CONSTITUTION:A jetting stream bed is formed from carbon black particles to be seed nuclei in a jetting stream bed reactor 10 and temperature of hot spots in the central part of the jetting stream bed is regulated to 600-1000 deg.C to blow a hydrocarbon gas into the jetting stream bed and thermally decompose or incompletely burn the hydrocarbon gas. Carbon unconsumed by the combustion is mutually bound to provide carbon black, which is partially deposited on the carbon black of the seed nuclei forming the jetting stream bed. The rest is converted into powder, which becomes itself seed nuclei to increase the grain diameter during capturing with the first dust collector 19, such as cyclone, and circulation. The resultant substance is then taken out of a carbon black discharge port 13.

摘要： PURPOSE:To enable to carry out drying of coal fuel under high safety, by drying the coal which is in the course of crushing and dust collecting processes through potential heat of exhaust gas by introducing the exhaust gas to be generated by a fluidized bed boiler into a crusher of the coal. CONSTITUTION:Exhaust gas exhausted from a fluidized bed boiler 6 is discharged finally into the open air from a stack 10 after passing through an exhaust path I , a mechanical dust collector 7, an exhaust path II, an electric dust collector 8, an exhaust path III, a heat exchanger 9 and an exhaust path IV. Exhaust gas to be exhausted from a dust collector 5 is led to a stack 10 through an exhaust path V. Exhaust gas come out of an exhaust gas outlet 14 is led to the dust collector 5 and led to the stack 10 through an exhaust path V. When crude coal is loaded through an inlet of the crude coal, it is crushed into a pulverized state by a crusher 3 and intermix contact between exhaust gas fed into through an exhaust gas inlet 13 and a crushed coal is done, through which sufficient drying of the coal is performed. In addition to the above, exhaust gas performing the intermix contact, in this instance, is combustion exhaust gas generated from the fluidized boiler 6, through which drying through heat of exhaust gas is done while extremely safe operation is kept continued.

摘要： PURPOSE:To simplify a unit by combining plows with an annular conveying body and unifying a driving system. CONSTITUTION:A number of plows 5 are mounted at a proper interval on a circular conveyor 3 driven in the peripheral direction along a rail 4. The plow 5 continuously delivers powder and grain bodies during the time it makes a round of a delivering outlet in the peripheral direction, allowing the powder and grain bodies to be contained in the circular conveyor 3. Then, the bottom part of the circular conveyor 3 is opened at a certain place, delivering and feeding the powder and grain bodies onto a delivering conveyor. Thus, the power of revolution of the plows and the driving force in the peripheral direction of an annular conveying body such as a circular conveyor or a turn table, etc. can be unified, enabling the simplification and miniaturization of a unit.

摘要： PURPOSE:To make possible uniform coal supply and to prevent a heating pipe from corrosion by a method wherein coal is supplied to a premixing fluidized bed to overflow mixture with fluid medium beyond the upper edge of the partition board into the main fluidized bed. CONSTITUTION:Grains of coal supplied from a coal feeder 10 into a premixing fluidized bed is mixed fully with fluid medium. The fluid medium is supplied by a fixed amount from a fluid medium supply pipe 11, mixture of coal and fluid medium that are fully mixed is overflowed always by a fixed amount over the partition board into the main fluid bed 7 to burn coal in a fluid state. Fluid medium containing ashes is exhausted from the ashes exhaust port 12. This amount of exhaust is brought under control in the manner that the amount of the coal overflowing the partition board and that of the admixture of the fluidized medium are made equal. Thus, the main fluidized bed is kept constant in its height, it is mixed sufficiently by the premixing fluidized bed to make the atmosphere uniform in concentration in the main fluidized bed and to prevent the corrosion of the heat transfer pipe.
