Electrical energy is one of the most important inputs for industrial and all round development of any country. Per capita consumption of electrical energy is a dependable indicator of the developmental level for any country. The onus for producing electrical energy falls on power plants to meet the everyday increasing demand. Power Plant Engineering is the outcome of the author’s teaching the same subject to engineering students for the last 19 years. It discusses all types of power plants in entirety, detailing each one’s merits and demerits, their engineering and technical aspects like the equipment required, working of the plant, scientific principles involved, their physical location, environmental hazards involved, and so on. Due emphasis has also been given to the management of waste generated by power plants, e.g. fly ash. Apart from technical and engineering aspects, it also discusses the economics part of power plants, recent developments in the methods of power generation, and prospects for solar and magneto-hydrodynamics power generation. Numerical problems, multiple choice questions and a review exercise is also appended at the end of each chapter. This book is useful for the students and teachers of electrical and mechanical engineering.
