摘要： A centrifugal separator (11) has a plurality of substantially planar walls, including a first wall (32), defining a vortex chamber (12) having an interior gas volume (31) and for establishing at least one gas vortex in the gas volume, and the gas volume has a cross section that is distinctly non-circular. In addition to conventional outlets, the separator includes a gas inlet (30) having at least one elongated jet-defining wall (40) with a free end portion (41) extending into the gas volume (31) a first distance from the first wall (32), to define a gas jet that extends substantially tangentially to the gas vortex in the gas volume. An insert (33') extends between the jet-defining wall (40) free end portion (41) and the first wall and defines a gas flow direction changing surface (47). The insert may be substantially solid refractory material, or include a number of cooling fluids circulating tubes, and a gas flow direction changing surface may be substantially planar or curved.

摘要： Particles in a fluidized bed reactor (e.g. a circulating fluidized bed reactor) are discharged from the reactor chamber (10) and then cooled (heat is recovered from them) in a processing chamber (16). This is accomplished in a particularly advantageous way by discharging the particles from the reactor chamber at a first level (e.g. through a non-mechanical seal or a classifying wall) into a lifting chamber (14). Upwardly flowing gas in the lifting chamber entrains the particles and lifts them into the processing chamber. After processing, the particles in the processing chamber are returned to the reactor chamber at level higher than the first level, at which point the pressure in the processing chamber is higher than the pressure in the reactor chamber. The particles may be classified in the lifting chamber by utilizing fluidizing gas to transport solid particles smaller than a predetermined size to the processing chamber while discharging larger particles from the bottom (38) of the lifting chamber.

摘要： A fluidized bed reactor system includes a reaction chamber (112) comprising a circulating (fast) bed, with a first grid (114) for the introduction of fluidizing gas, and a bubbling (slow) fluidized bed (116) having a second grid (120) for introduction of fluidizing gas. The second grid is mounted below the first grid. First (122) and second (132) interconnections are provided between the circulating and bubbling beds. Particles flow from the circulating bed through the first interconnection to the bubbling bed, and vice versa for the second connection. The interconnections are positioned with respect to each other so that the pressure and density conditions within the bed are the sole mechanisms that provide the driving force to control the flow of particles from the circulating bed to the bubbling bed. An indirect heat exchanger (128) may be located in the bubbling bed for cooling particles, and various constructions of partitions (130) may be provided for dividing up the bubbling bed and defining the interconnections.

摘要： Disclosed is a method and system for recovering energy from low-grade fuels such as industrial, municipal and agricultural waste, low-grade carbonaceous fuels such as lignite and similar solid fuels in which the fuel is comminuted into small particles and slurried in water. The alkali content of the slurry is adjusted to be at least about equal to the chemical equivalent of the halogen content of the slurry and, following pressurization of the slurry, it is heated sufficiently so that the substantial portion of chemically bound oxygen in the fuel separates therefrom as carbon dioxide, leaving a slurry including char particles and dissolved impurities such as halogen salts. The char particles are removed from the slurry and reslurried with just enough halogen-free water to provide the slurry with the needed viscosity to maximize the energy density thereof. The char particles are then reacted with air at a temperature below their ignition value to convert the fuel value of the low-grade fuel into thermal energy which is then further used, for example, to drive a turbine (253, 255, 257).

摘要： Solid particles are transported from a first chamber (e.g. combustion chamber of a fluidized bed reactor) to an adjacent second chamber (e.g. a transporting and/or processing chamber) by providing a solid flow seal, a controllable solid flow valve, or both in a partition between the chambers. Transporting gas is introduced into the first chamber to transport solid particles as multiple solid flows from the first chamber to the second chamber. A number of narrow passages in the partition wall disposed one on top of the other, and having a height to length ratio less than 0.5, height less than 50 mm, act as the solid flow seal and controllable solid flow valve in the partition. The transporting gas may be introduced through the bottom of the first chamber, a side wall opposite to the partition wall, or both, and the partition wall may be lined with refractory adjacent the first chamber with passages in the refractory lining being made of combustible material which is burned away during heating of the refractory lining. The passages may also slant upwardly slightly from the first chamber to the second chamber, e.g. about 15 degrees.
