Biomass Power Plant
Biomass power plants efficiently convert organic matter into clean, renewable energy. By burning plant or animal-derived waste in a boiler, the heat generated is transformed into clean electricity through a Rankine cycle, thereby reducing reliance on fossil fuels.
In small biomass power 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 of traditional biomass power 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 BIOMASS WASTE INTO CLEAN POWER
Biomass Power Plant with ORC
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.

How ORC Biomass Power Plants work
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.
