Exergy Analysis of a Molten Carbonate Fuel Cell-Turbo Expander-Steam Turbine Hybrid Cycle

Exergy analysis of an integrated molten carbonate fuel cell-turbo expander-steam turbine hybrid cycle has been presented in this study. The proposed cycle has been used as a sustainable energy approach to provide a micro hybrid power plant with high exergy efficiency. To generate electricity by the mentioned system, an externally reformed molten carbonate fuel cell located upstream of the combi...

The Application of Switching Control to Boiler-Turbine Coordination in Marine Steam Power Plant

In the marine steam power plant, the main boiler has the small size and the little heat capacity. However, marine ship requires high maneuverability, when it is running, the loads varied frequently, and the varying range is big, and this will cause the boiler security problem, such as over-pressure or under-voltage. The marine steam power plant boilerturbine coordinated control strategy is to s...

Metallurgical fatigue failure analysis of the brazed steam turbine blade

In this paper, failure mechanism of a 17th stage blade of an 82.5 MW steam turbine that caused damage to the internal turbine compartment and the adjacent blade equipment has been studied. In order to determine the cause of failure and prevent similar events, various metallurgical and mechanical investigations including chemical composition analysis, metallography and microstructural analysis, ...
