This plant has an electrical output of 800 kW and a thermal power of 760 KW. At the biogas plant in Trechwitz, an unconventional heat utilisation model was installed. The waste heat from the CHP unit is used to generate power in an ORC unit (Organic Rankine Cycle). The heat goes into an evaporator, and the operating liquid is converted into pressurised steam. The steam is depressurised by ...

Energy–Utilisation Diagram (EUD) has been used to identify exergy loss in general process units, whereas Power Availability Diagram (PAD) provides the difference between exergy changes of two pressure exchangers. Two modifications of the original PAD are proposed for better exergy loss visualisation. Firstly, the energy donor curve is shifted to the location of energy acceptor. Secondly, arrows ...

The geothermal energy that is stored in the earth is so vast that could supply all the energy needed by humanity. The difficulty in tapping this energy lies in its diffusivity. The geothermal energy in regions near volcanoes is close to the surface and easy to use economically. In this paper a vapour dominated system will be examined. The electricity that is produced from such a system is ...
