  • Energy and exergy analysis of a novel multigeneration system producing cooling, heating, power and pure water

    A novel multi–generation system producing power, pure water, cooling and heating is proposed and analysed in detail. The system comprises a hybrid generator-absorber heat exchanger (GAX), the Organic Rankine Cycle (ORC), the absorption heat transformer (AHT) and a desalination system. For comparison purposes, three working fluids, including R123, Isopentane and n–butane are considered in the ORC. ...

  • Allready-Box brings security to production of bioenergy

    Animal feed manufacturer Futtertrocknung Mindelheim eG of southern Germany has been operating a co-generation power station since 2008. During the summer months, this power station uses ecological methods to generate the heat and electricity the company needs to dry soilage. Utilizing a year-round, low-temperature heating network, it supplies local industrial firms and public institutions with ...

  • Extension of energy–utilisation diagram to power availability for exergy loss analysis

    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 ...

  • Exergy analysis of geothermal electricity using the Kalina cycle

    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 ...

  • A necessary condition for optimum Rankine cycle power plants

    Consumers pay more for electricity than necessary partly because commercial power plant operating criteria are not universally valid. Although such plants are commonly designed to provide electricity at least cost for given conditions, operating criteria lack a rigorous thermodynamic basis. The current empiricism alone costs US consumers billions of dollars per year. This dilemma exists because ...

  • Utilisation of deep geothermal energy for heating purposes

    The Hot-Dry-Rock-(HDR) technology allows a location-independent utilisation of geothermal heat, because aquifers in deep formations, i.e. layers filled with water, are not necessary. The flow paths for the circulating water in a depth of 4 km are created by hydraulic fracturing of existing gaps. Due to the fact that this new technology is quite cost-intensive, high annual load duration of the ...

  • A new Rankine cycle for hydrogen-fired power generation plants and its exergetic efficiency

    A novel power generation cycle is proposed in this paper taking hydrogen as fuel and using steam generated by hydrogen firing as working fluid. The progress of the development work and side issues such as the application of hydrogen combustion turbines to environmentally clean fossil fuel power plants for early commercialisation of the system are reviewed. We propose the hydrogen-fired Rankine ...
