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 ...

Energy and exergy analysis of a gas turbine power plant in Algeria
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 ...

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 ...

Prime Power Generation - Case Study
A national electricity grid must always be able to meet the needs of its users. This requires it to be: stable, maintaining the required electrical frequency (50 Hz in the UK); balanced, continuously matching supply to demand; and adequate, ensuring total generation capacity is never outstripped by demand. Grid supply is split into three tiers: base, intermediate, and peak load. Baseload is a ...
