Efficient energy from biomass

Micro-CHP system based on an innovative, fuel-flexible biomass-fired steam generator and a micro steam turbine

Powering Tomorrow

CO2 targets require immediate action: CHP plants using renewable fuels make a direct contribution to achieving the EU's climate targets (-55% emissions by 2030, climate neutrality by 2050).

Efficiency counts twice: By generating electricity and heat simultaneously, CHP systems meet the requirements for greater energy efficiency and reduce primary energy consumption.

Decarbonization of heat and electricity is crucial: The heating sector is lagging behind – biomass CHP enables fossil-free heat supply in municipalities and industry.

Renewable and secure supply: Biomass CHP delivers controllable, renewable energy – this ensures supply while reducing fossil fuel dependencies.

Why invest in a new CHP plant now?

Areas of application

  • Existing heating plants and energy suppliers also for base load coverage in summer

  • Municipalities

Decentralized heating networks

  • Hotels and wellness facilities

  • Multi-unit residential buildings in rural areas

  • Small industrial businesses

  • Schools

Decentralized
consumers

  • Forestry and agricultural businesses

  • Wood processing companies such as sawmills, carpentry shops, pellet and wood chip plants

Decentralized operations with their own fuel

Technological advantages over competitors:

✓ Comprehensive fuel flexibility, from low-quality moist wood chips to agricultural waste

✓ Low maintenance and operating costs thanks to robust steam boiler technology and inexpensive fuels

✓ No trained boiler operator required for operation, as the patented design enables classification as a low-risk system in accordance with boiler regulations

✓ High overall efficiency of 90 %

✓ Reduced investment costs due to cascade connection of several steam boilers

→ up to three steam generators can supply one turbine

MultiFuel-CHP consisting of

Biomass grate furnace:

Fuel-flexible grate furnace with 170 kW-fuel power and low emissions thanks to multi-stage combustion and particle separation.

A wide range of biomass fuels can be used:

✓ From high-quality wood chips to agricultural and forestry residues

✓ Water content up to M50

✓ Particle size up to G60

Steam generator:

✓ Patented, innovative boilerless steam generator with a steam power of approx.160 kW

✓ No steam boiler operator or additional training for the operator required thanks to the special design

✓ Low-maintenance operation thanks to separation of combustion and power generation via steam cycle with high overall efficiency of up to 90 %

Micro steam turbine & heat utilisation:

✓ Conversion of superheated steam into electricity in a highly efficient microturbine generator unit with an electrical output of 21 kW

✓ Supplying around 130 kW of heat for use as process heat or for heating purposes
