  • Exergetic analysis of gas turbine plants

    An exergetic analysis was performed for a 116-MW gas-turbine power plant. Mass and energy conservation laws were applied to each component of the system. Quantitative exergy balance for each component and for the whole system was considered. In this study, the exergy of a material stream is decomposed into thermal, mechanical and chemical exergy and an entropy-production flow. The effect of a ...

  • Risk-based maintenance of gas expansion turbines in steel plant

    Unexpected failures, loss of production, higher maintenance costs and down time associated with the failures of equipment are major problems in any plant. Adopting the risk-based maintenance (RBM) approach helps in designing an alternative strategy to minimise the loss resulting from these breakdowns or failures. The methodology consists of four modules: system definition, risk assessment, risk ...
