As a distributor and installer for both of these systems and our many years of expertise in ORC integration with a range of heat sources, we are well placed to offer a turnkey and viable solution recovering heat, otherwise rejected, to produce electricity for sale to the National Grid or to offset site loads and where applicable, used for downstream process heating.
How does ORC work?
Process: The working fluid in the ORC is pumped to an evaporator where it absorbs heat from the heat source. This then changes the working fluid into a high-pressure gas vapour. This gas is then expanded through a small turbine coupled to a high speed (no gearbox) electrical generator in the Integrated Power Module to produce electrical power. The gas is then turned back into a liquid as it passes through the condenser and the cycle then repeats itself.
Heat Source: This is often in the form of hot air or hot gas which is ducted to the evaporator of the ORC as described. This can be via a heat exchanger depending on the specific installation.
Markets
The following are markets that we work in with ORC installations;
Biomass Burner – hot gas 530°C – 1000°C
Biomass Steam – 1.5 – 10t/hr flow
Biomass Hot Water – 80°C – 150°C
Anaerobic Digesters – engine exhaust 450°C – 550°C and jacket water 90°C
Landfill sites – engine exhaust 450°C – 550°C and jacket water 90°C
