BIOMASS

The Triogen ORC can be used with biomass combustion, for example sawdust, chips, bark and treated wood; and other biomasses, such as straw, rice, husks and bio-sludge, as well as other high organic-content waste. The Triogen ORC will be connected to the combustor. The Triogen ORC converts the flue gasses from the combustor into electricity.

Benefits

• Enables local scale, decentralized power and heat production
• Close to fuel source and/or heat
• Conversion of difficult materials into revenue sources instead of costly disposal
• Highest efficiency solution on the market in this power range
• Compared to steam plants, ORC requires less supervision, no need for water treatment and lower maintenance costs

SOLUTION FOR HIGH-QUALITY FUELS:

DIRECT EVAPORATION

• Fuel and combustion: Woods chips or other high-grade fuel is fed into a furnace, gasifier/flare (1.2 MW_th per ORC)
• Flue gas handling: The flue gas passes through a heat exchanger(“evaporator”) where it heats up the ORC working medium.
• Power conversion: In the ORC, a turbine drives the generator producing up to 170 kW power; the ORC also provides heat in the form of cooling water. Multiple ORCs can be operated in parallel.

SOLUTION FOR LOW GRADE FUELS:

INTERMEDIATE AIR LOOP

• Fuel and combustion: Chicken litter, manure, waste wood, RDF or other low grade fuel is fed into a burner (~1.3 – 1.6 MW_th  per ORC) that produces hot flue gases
• Flue gas handling: The flue gas passes through an air-air heat exchanger designed to handle aggressive flue gases with high ash-content. It heats up air which runs in a closed loop to a heat exchanger (“evaporator”) where it heats up the ORC working medium.
• Power conversion: In the ORC, a turbine drives the generator producing up to 170kW power; the ORC also provides heat in the form of cooling water. Multiple ORCs can be operated in parallel
