摘要： PURPOSE:To enable even powdery materials to make steady combustion by covering the lower half of a annular slit with a partition plate and providing a cooling-air jetting port on the upper part of a fixed wall. CONSTITUTION:An annular slit 11 is formed between a rotary kiln proper 7 and a fixed wall 10, the lower half thereof is covered with a partition plate 3 for preventing the inflow of cooling air and compensating the shortage of introduced cooling air due to the plate 3. The incineration 12 such as heavy crude oil ash supplied from an incineration supply shoot 4 is incinerated by the flame of a burner 5. Then, since cooling air jets through an upper slit 11a, the incineration 12 is combusted without being blown up and the flame of the burner 5 turns downward so that the incineration 12 is combusted favorably.

摘要： PURPOSE:To improve the circulating characteristics of fluidized heat medium and thereby to improve the operational efficiency of the boiler by providing a cleaning means and a drying means in the regenerating and circulating passage of fluidized heat medium. CONSTITUTION:The fluidized heat medium used in a incinerator 1 is extracted regularly and continuously by a medium extracting nozzle 8 and cleaned by a water washer 9 to remove attachements thereof and then drained by a draining means 10. Then the fluidized heat medium is transported by a transporter 11 to a drying means 15 to remove water remining therein completely. The drying means 15 has a drying tower 22, a ventilation member 19 disposed in the lower portion of the tower 22, and an air inlet 20 on the bottom of the tower 22. In operation, the cleaned fluidized heat medium 23 is thrown inside the drying tower 22 on the ventilation member 19 and hot air is fed into the tower 22 through the air inlet 20. The fluidized medium 23 is dried while it is fluidized. Thereby the fluidized medium 23 can be prevented from solidifying and accumulating to make a smooth circulation, resulting in an improvement of operational efficiency.

摘要： PURPOSE:To supply quantatively substance with high viscosity such as sludge etc. by letting steam flow into a shaft of screw feeder, where the steam is heated, and by equipping the outlet of the feeder with a slit plate. CONSTITUTION:A shaft 2 of screw feeder transporting the viscous substance in a hopper 9 is designed by a jacket construction, into which steam is supplied, and the shaft 2 and screwed blade 1 are heated. By this construction, the moisture in the viscous substance is gasified and the surface of screw is covered by the vapour, so that the substance's attaching to the screw is prevented and the substance can be transported continuously in a constant quantity. Further, variation in the supply quantity due to any change in the level or property of the material in the hopper 9 is suppressed by equipping the outlet with a plate 10 having a slit hole, which is to work as a resistance plate. Thus stabilized supply in a constant quantity is assured.

摘要： PURPOSE:To obtain an EP ash supplier which eliminates a possibility of EP ash clogging and a need of provision of a regenerator of a fluid medium by providing a pump which can transport a fluid of a high viscosity to the upstream side of a fluidized furnace. CONSTITUTION:The dry EP ash E2 temporarily pooled in a hopper 30c is introduced into a humidifier 18 via a rotary valve 31. On the other hand, the fluid medium increased in volume by molten matter being attached in the course of EP ash incineration within the fluidized furnace 1 is floured by a certain amount through an overflow pipe 5 and supplied to the humidifier 18 after cooled to a certain temperature by a medium cooling means 17. The EP ash humidified in a proper condition, the fluid medium regenerated and the molten matter removed from the fluid medium are mixed by a mixer 19. Then the mixture is pooled temporarily in a hopper 20 and then sent to the pump 21, which feeds the mixture of a high viscosity via a pair of supply pipes 22a and 22b to a fluidized layer from the stop and side wall of the furnace 1.

摘要： PURPOSE:To prevent clogging of a chute for feeding ash of heavy crude oil collected by an electric dust collecting apparatus or the like, by coating the inner surface of the chute with a material capable of preventing sticking of ash, and increasing the setting angle of the chute. CONSTITUTION:A chute 14 for feeding EP ash(ash of heavy crude oil) is connected to a case conveyor 9. The outlet end of chute 14 is extended through the wall 13 of a swirling fluidized bed furnace 1 and opens toward a swirling fluidized bed 5. The inner surface of shute 14 is coated with a resin layer for preventing sticking of EP ash. As the resin, there can be used preferably fluorine containing fibers like Teflon (copolymer of tetrafluoroethylene and hexafluoropropylene) having a high chemical resistance. Furhter, the setting angle alpha of EP ash feeding shute 14 to furnace 1 is selected to be larger than 60 deg. and the portion of chute 14 extended through furnace wall 13 is made in a double-pipe structure, so that cooling medium like water can be passed through the space formed between the outer pipe 11 and the inner pipe.

摘要： PURPOSE:To improve an operating efficiency of an incinerator by preventing thermal damage of bag filter cloth. CONSTITUTION:Inlet and outlet gas temperatures of a bag filter 5 are always measured by temperature switches 19, 20, and its differential temperature is continuously obtained by a temperature difference calculator 21. When the outlet temperature starts to rise with respect to the inlet temperature, a switching valve 13a provided at a low-temperature gas duct 13 is opened by an output signal from the calculator 21, cooling low-temperature gas is introduced to the inlet of the filter to lower the inlet temperature. If the outlet temperature still rises exceeding the inlet temperature, the feed of material to an incinerating furnace is reduced to decrease a scattering amount of combustion dust to be exhausted from the furnace to the filter.

摘要： PURPOSE:To minimize adhesion of soot and dust and maintain high dust collecting efficiency to make inlet angle and outlet angle of guide blades of an axial- flow cyclone in a fixed range. CONSTITUTION:In an axial-flow cyclone that processes exhaust gas etc. containing highly adhesive soot and dust, inlet angle alpha of guide blades is made about 15 deg.-50 deg., preferably about 25 deg.-40 deg., and outlet angle beta is made about 15 deg.- 25 deg., preferably about 18 deg.-23 deg.. By this way, adhesion of soot and dust to the guide blades 13 can be minimized, and dust collecting efficiency of the dust collector can be always kept high.

摘要： PURPOSE:To reduce the consumed quantity of fuel, by inserting cooling gas injection nozzles into an exhaust gas passage, the cross-sectional area of which gradually decreases in the downstream direction, and orienting the nozzles in the direction. CONSTITUTION:An incinerator 1 comprises a fluidized bed section 2 and a hollow column section 3. The exhaust gas passage 8, the cross-sectional area of which gradually decreases, is coupled between the column section 3 and a flue 4. The flow of exhaust gas is turned by an angle of 90 deg. at the top of the column section 3. The cooling air nozzles 7 are inserted into the top of the column section 3 to sufficiently mix the exhaust gas with cooling air. The axis of the nozzles has an angle alpha to the horizontal plane and another angle beta to the tangential direction on the wall of the column section.

摘要： PROBLEM TO BE SOLVED: To prevent the plugging of the outlet part of a cyclone with a falling refractory by providing a collecting means for collecting the falling refractory inside of a cyclone vessel with respect to the cyclone vessel for separating ash portion in a combustion gas and using the refractory as an inner wall. SOLUTION: The high temp. combustion gas flowing in from an inlet plenum provided at a top center part of the cyclone vessel 7 is distributed to plural numbers of cyclone main bodies 15 arranged on the peripheral part of the side wall of the cyclone vessel 7, descends along the cylindrical drum part inside wall from the inlet of each cyclone main body 15 while swirling and during this time, the ash portion moves to wall direction by centrifugal force and is separated from the gas stream. In such a case, a collector 37 made of a grating member is mounted between a vessel outlet 35 and an ash portion outlet 21 of the cyclone main body 15. The position where the collector 37 is mounted can be at the inside wall of the cone part 29 at the downstream side of the ash portion outlet 21 where the lined refractory is most probably stripped and falls down though not particularly restricted.
