Fluidized Bed Incinerator

Our fluidized bed incinerators guarantee outstanding performance, economy and reliability.

The fluidized bed incinerator is a refractory brick lined steel cylinder with an air distribution system equipped with nozzels. Air is blown through the nozzles upwards into a sand layer above the air distribution system. The air fluidizes the sand layer equally and so the sand layer expands to the fluidizing bed being 1.5 m high. The incinerator and the sand layer are heated up by means of burners over the ignition temperature of the combustible. Now the combustible containing water, organic and inorganic substances is fed into the fluidized bed and ignites. The water evaporates and becomes superheated, the organic substances are combusted and the inorganic substances are glown.

The characteristics of the RASCHKA - fluidized bed incinerator are:


  • air distribution system: ceramic nozzle bottom, alternatively steel nozzle bottom or air distribution system permeable for foreign matters, air nozzles of special design to ensure even and exact air distribution
  • discharge of bed material and foreign matters during operation of incinerator
  • fuel feeding into the furnace by means of the RASCHKA-spreader which serves for an even distribution over the entire surface of the fluidized bed
  • injection of secondary air for controlled staged combustion
  • extremely long retentention times and low flow velocity in the freeboard, thus complete combustion
