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...

Biomass based Indirectly Heated combined heat and power plant can be an excellent option for community scale power generation. The thermal performance of such a plant employing air-turbo generator block and bottoming steam turbine block has been analyzed over a range of pressure ratio (2-16) and for different turbine inlet air temperatures (1073, 1273 and 1373K). The conventional GT combustion ...

Three alternatives for integrating a solar field with the bottoming cycle of a combined cycle plant are modeled: parabolic troughs with oil at intermediate and low cycle pressures and Fresnel linear collectors at low cycle pressure. It is assumed that the plant will always operate at nominal conditions, using post-combustion during the hours of no solar resource. A thermoeconomic study of the o...

The improvement of gas turbines flexibility has been driven by more use renewable sources power due to environmental concerns. There are different approaches improving turbine flexibility, and they have performance implications for the bottoming cycle in combined (CCGT) operation. CCGT configuration is favourable generating output, higher thermal efficiency that key economic viability electric ...

Dish concentrators permit the collection of very high-temperature heat, at temperatures limited only by the properties of the containment vessel material. Using this heat efficiently is a major challenge in the design of energy conversion systems for dish concentrators: the heat must be used either immediately on the dish, or else transported, with losses, to a remote energy conversion device. ...
