Biomass Power Plants
In small biomass plants, ORC technology is the ideal choice due to its high efficiency, availability and ability to follow loads dependent on fuel supply. In addition, the elimination of the steam turbine for traditional biomass solutions brings with it a number of maintenance and operational advantages.
The Exergy solution for power generation from biomass is an ORC module utilizing the Radial Outflow Turbine coupled with a biomass boiler
TRASFORMING WASTAGE INTO CLEAN POWER
The ORC module can be used to produce electrical power and thermal power, the latter utilized for combined heat and power production (CHP) purposes such as:
The biomass feed for the boiler that can be exploited as “fuel” includes, for example: leftover materials from the wood industry, olive waste, husks of cereals and fruit and other secondary biomass.
Why install a biomass plant?
An ORC biomass power plant offers several advantages:
THE POSSIBILITY TO FEED BOTH HEAT AND POWER NEEDS IN ONE SOLUTION
Higher power and efficiency to capital cost ratio
Electrical efficiency up to 30%
MULTIPLE PRESSURE ADMISSIONS POSSIBLE ON A SINGLE DISK
High reliability
FLEXIBILITY IN BIOMASS FEED QUALITY
Wider range of application possibilities
Proven and widely applied technology
SMALL MODULAR AND LIGHTWEIGHT PLANT
Easy installation
Few civil works required
NO STEAM TURBINE
Simpler operation
Reduced maintenance
NO WATER CONSUMPTION
Reduced environmental impact
No need for plant proximity to a water supply

Orc cycle from biomass
The boiler, via the combustion process, converts the biomass in thermal power to feed the ORC module. The hot exhaust gas warms up the intermediate fluid in a heat exchanger. The ORC-boiler interface circuit transfers thermal power from the boiler to the ORC evaporator. Commonly employed intermediate fluids between the boiler and ORC are thermal oil, pressurized water or steam.
The interface fluid transfers heat to the organic fluid in the ORC evaporator, where it vaporizes. The vaporized fluid then passes to the turbine. Here, the vapor expands, causing the turbine to spin and create electricity in the generator.
