Biomass is used as fuel to power the following cogeneration plant on a school. The turbine drives an electric generator to produce electricity, and part of the steam is extracted to provide heating to campus buildings. The boiler provides 106 kg/h of steam at 6 MPa, 520 °C, of which 4x105 kg/h is extracted between the first and second turbine stages at 1 MPa and diverted to the building heating load. Condensate returns from the building heating load at 0.95 MPa, 115 °C, and it is mixed with liquid exiting the lower pressure pump at 0.95 MPa. The entire flow is then pumped to the boiler pressure.
