Boiler's nominal output

~3,300 to 12,000 kW


  • Electrical power and heat by means of ORC turbine OR
  • Process heat at high temperature levels (supply temperatures > 150 °C to 315 °C)


  • Optimised for use with ORC combined heat and power OR for high temperature coupling
  • Capacity ranges attuned to common ORC modules
  • Available as distributed multiple flue systems for long periods of continuous operation even with heterogeneous fuels (bark and agricultural management materials) OR as cost-effective and space-saving 3-flue systems in coiled configuration for applications with particular fuel qualities, upon customer request.
