For projects where minimising the cost of minimising staff costs and other running costs is essential, biomass CHP systems using Organic Rankine Cycle (ORC) turbines fed by biomass boilers, can be an attractive solution. Such systems, while requiring a higher capital cost compared to biomass gasifier based CHP plants, can run largely unattended (if fuel feeding is automated). These maximise uptime and efficiency at a minimised operational and maintenance cost, resulting in a skid-mounted modular machine with plug-and-play connections for convenient installation.
ORC based systems are driven by a biomass boiler that evaporates a special working liquid. This is then used to drive a specially designed expander (turbine) and generate electricity. After the working cycle is finished, the expanded working liquid vapour is delivered to a condenser and then reused in a continuous cycle.
Flex Technologies can supply customised ORC – based systems using boilers that burn any of the following fuels:
- Wood chips and other waste wood
- Olive pomace and pits
- Corn stalk and cob
- Cotton stalk and cotton gin waste
- Any other biomass fuel that can be burned in a boiler
Solutions are available to retrofit ORC systems to existing steam boilers or superheated water boilers.
