Gas Turbine Articles & Analysis

The role of gas turbine power plants in electrical energy production has been considerably increased in the last two to three decades. Various methods have been proposed to improve the performance of gas turbine cycles. In this research, two methods, a reheat cycle (RC) and a cycle with a reheat and a recuperator (RHC), were investigated and compared with a simple cycle (SC). The main objective ...

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 ...

The externally fired combined cycle (EFCC) which utilises coal as the primary fuel through a gas turbine cycle is a clean coal technology. Natural gas is used as the supplementary fuel, but the ultimate goal of the EFCC concept is a coal only option. In this study, the performance of the EFCC plant is evaluated based on the first and the second laws of thermodynamics, considering various levels ...

An exergy analysis of a twin ABB GT13E2 Gas Turbines (GTs) power plant (2 ? 146.2 MW) is presented in this paper. This plant is running since 2004 at F'Krina in the northeastern part of Algeria. The analysis was performed by the flow-sheet programme, 'Cycle-Tempo'. At off-design load (83%), the plant and its apparatus conserve nearly the same design load performances. However, the performance of ...

Exergy–based methods are powerful tools for developing, evaluating and improving an energy conversion system. Conventional exergy–based analyses have limitations, which are significantly reduced by the so–called advanced analyses. The latter evaluate: (a) the interactions among components of the overall system, and (b) the real potential for improving a system component. The main objective of ...
