Recent years have seen growing interest in combined power plants. Their competitive advantages, stemming from higher efficiencies and environmental benefits, are now widely recognized. This book provides detailed analysis of the basic thermodynamics and economic implications of such plants, and includes details of recent developments in Europe, USA and Japan. It will be invaluable to practicing engineers, providing a comprehensive guide to all aspects of combined power plants, and is essential reading for graduate and undergraduate students in mechanical engineering. It will also be of interest to policy makers, economists and environmental scientists.
