Definitions

  • the invention relates to a reactor for the gasification of a carbon-containing fuel.
  • downstream cyclones are devices which are arranged separately from the reactor and are designed as refractory brick pressure vessels and must be designed for a specific operating point.
  • the invention has for its object to provide a dedusting system based on cyclone separators for a coal gasifier, which is less expensive to manufacture and therefore less expensive to manufacture, and which allows controllability in the event of load changes.
  • the coal gasifier is a pressure vessel, the pressure jacket and the refractory lining are not required for the cyclones arranged inside the reactor.
  • the cyclone inlet of the individual cyclones can be closed by a movable plate. Actuation takes place outside the reactor via electrically driven threaded spindles.
  • the reactor (1) for coal gasification shown in FIGS. 1 to 4 is a type of reactor as described, for example, in German patent application P 36 00 432.4, namely a horizontal fluidized bed reactor.
  • a part of the reactor chamber (12) of the reactor (1) is indicated on the far left, next to it on the right - separated by a weir (11) - the ash room (13) and on the far right - again separated by a weir (11) - the dedusting room (14).
  • the four cyclones are identical.
  • the gas supply is uniform due to the excess pressure prevailing in the reactor.
  • the cyclones are made of HT sheets. A pressure jacket and a fireproof brickwork are not required.
  • the clean gas outlet pipes of the cyclones contain compensators on the pipe bushing through the reactor wall.
  • individual cyclone inlets (3) can be closed by plates arranged on threaded spindles in order to keep the separation efficiency constant during load changes.
  • the actuation takes place outside the reactor via attached electric motors.
  • the support of the plate on the cyclone inlet does not require a seal because there is no significant differential pressure.
  • the closure device (10) is carried out through the reactor wall in water-selected fabric bushings with sealing gas rings.
  • Water-cooled cell wheels (8) are arranged to discharge the dust separated by the hot gas cyclones (7).
  • the ash from the ash room (13) is discharged with the help of the water-cooled cell wheel (9).
  • the arrangement of the hot gas cyclones within the reactor creates the possibility, based on the geometric conditions, of discharging ash and dust according to FIG. 4 with only one lock system (15).
