  • Thermal exergy optimisation for an irreversible cogeneration power plant

    The optimal design model, based on exergy analysis, of an irreversible cogeneration cycle has been presented using finite-time thermodynamics. The external irreversibility is due to the thermal resistance between the system and the heat reservoirs while the internal irreversibility is due to the non-isentropic compression and expansion process within the system. The internal irreversibility of ...

  • A Structured Approach to Steam System Improvement through Utility System Design and Optimisation

    Optimal operation of site utility systems is becoming an increasingly important part of any successful business strategy as environmental, legislative and commercial pressures grow. A reliable steam model allows a clear understanding of the system and of any operational constraints. It can also be used to determine the true cost of improvement projects, relating any changes in steam demand back ...

  • Thermodynamics of a desalination system at nuclear power stations

    Nuclear power engineering is developing steadily in industrial countries. This is caused by features of using nuclear fuel and high environmental safety of nuclear power stations. At the same time, the thermodynamic efficiency of nuclear power stations is lower than indices of thermal power stations operating on gas, coal or oil fuel. This efficiency does not usually exceed 30–35%. Hence more ...
