  • Patent number: 4848276
    Abstract: A power plant utilizing combustion of fuel in a fluidized bed contains a particulate sulfur-absorbing material. A discharge device for bed material and ashes includes a crusher which breaks down the material so that it can be transported away or so that unconsumed absorbent in the bed material is exposed for reuse in the bed. The crusher has a stationary grinding portion and a rotating grinding portion receiving bed material. Scrapers selectively scrape off layers of material during rotation of the rotating grinding portion thus distributing the material around the periphery of the grinding portions.
