Power Cycles and Energy Efficiency: The Enhancement of Efficiency

This unique book provides a fresh perspective on the thermodynamics of the classic energy cycles. The author considers modifications of various power cycles that have the potential to double the efficiency of electricpower generation. The book offers a detailed discussion of nonadiabatic behavior during compression and expansion, which is a topic of central importance in the enhancement of efficiency. Coverage includes practical ways of recouping waste heat from a modified Joule cycle, latent heat recovery, and power and latent heat cycles utilizing compression and expansion along the vapor-pressure or saturation curve of the working fluid. The methodology discussed can be applied directly to geothermal and solar energy recovery, and is particularly adapted to skid-mounted units, as used for gas-fired turbine/generators. The evidence presented shows that significant increases in efficiency are still possible in spite of the conventional wisdom about the classic powercycles.
