  • Thermal performance of gas turbine power plant based on Exergy analysis
    Applied Thermal Engineering, 2017
    Co-Authors: Thamir K Ibrahim, Ahmed N. Abdullah, Rizlman Mamat, Omar I. Awad, Firdaus Basrawi, Gholamhassan Najafi, Ftwi Yohaness Hagos
    Abstract:

    This study is about energy and Exergy analysis of gas turbine power plant. Energy analysis is more quantitatively while Exergy analysis is about the same but with the addition of qualitatively. The lack quality of the thermodynamic process in the system leads to waste of potential energy, also known as Exergy destruction which affects the efficiency of the power plant. By using the first and second law of thermodynamics, the model for the gas turbine power plant is built. Each component in the thermal system which is an air compressor, combustion chamber and gas turbine play roles in affecting the efficiency of the gas turbine power plant. The Exergy Flow Rate for the compressor (AC), the combustion chamber (CC) and the gas turbine (GT) inlet and outlet are calculated based on the physical Exergy and chemical Exergy. The Exergy destruction calculation based on the difference between the Exergy Flow in and Exergy Flow out of the component. The combustion chamber has the highest Exergy destruction. The air compressor has 94.9% and 92% of Exergy and energy efficiency respectively. The combustion chamber has 67.5% and 61.8% of Exergy and energy efficiency respectively while gas turbine has 92% and 82% of Exergy and energy efficiency respectively. For the overall efficiency, the plant has 32.4% and 34.3% Exergy and energy efficiency respectively. To enhance the efficiency, the intake air temperature should be reduced, modify the combustion chamber to have the better air-fuel ratio and increase the capability of the gas turbine to receive high inlet temperature.

  • Industrial energy-Flow management
    Applied Energy, 2007
    Co-Authors: Marko Lampret, Venceslav Bukovec, Andrej Paternost, Srecko Krizman, Vito Lojk, Iztok Golobič
    Abstract:

    Deregulation of the energy market has created new opportunities for the development of new energy-management methods based on energy assets, risk management, energy efficiency and sustainable development. Industrial energy-Flow management in pharmaceutical systems, with a responsible approach to sustainable development, is a complex task. For this reason, an energy-information centre, with over 14,000 online measured data/nodes, was implemented. This paper presents the energy-Flow Rate, Exergy-Flow Rate and cost-Flow Rate diagrams, with emphasis on cost-Flow Rate per energy unit or Exergy unit of complex pharmaceutical systems.
