Schematic Overview Of SSI
(Sewage Sludge Incineration) Process

Fluidized Bed Incineration (FBI) Plants
Time Proven, High Efficiency, Self-Sustaining, Reliable and Future Proof
  • Specially designed for low calorific value waste (e.g. sludge from Wastewater Treatment Plant) which
    cannot be burned in a rotary kiln.
  • With intensive mixing in the hot sand bed, the sludge is broken-up in small particles with the advantage that the remaining water can be evaporated very fast and completely
  • Homogeneous burning in FBI enables a very even temperature distribution across the diameter of FBI;
    this allows the system to achieve very low emission values (e.g. NOx, SOx, CO etc.).
  • Capable of meeting stringent phosphorous recycling and ash collecting requirements
Application Range
  • Sewage sludge, waste sludge from industry and refineries
  • Biomass, waste wood, bark, secondary fuel
  • Ballast coal, low quality coal, pyrolysis coke, coal sludge
  • Residuals from paper, cellulose- and chemical industry
  • Domestic waste, waste from slaughterhouse, carcass
