Fluidized bed

Thermal recovery of sewage sludge

Fluidized bed technology has been established at Küttner for many years. The first foundry sand regeneration facilities were built in the 1990s and successfully used. The adaptation of the existing "Know How" and the handling of low calorific fuel in environmental technology led to sewage sludge incineration on a fluidized bed basis. In addition to the high operational reliability of the thermal utilization, the focus is on energy efficiency. Over 80% of the introduced fuel heat output is utilized in the process. The thermal energy from combustion, after use for sewage sludge drying and air preheating, is made available for further applications, such as:

  • district heating
  • power generation
  • Process heat for industrial applications

The consideration and identification of the energy flow represents the central point in the system design. Küttner designs and supplies process plants worldwide. Concepts for individual components, units up to turn-key projects are developed in close cooperation with the customer. Individual solutions for the effective utilization of energy as well as the minimization of material flows are a central point. These approaches are implemented in new concepts as well as in the integration into existing infrastructures.
