Excerpt from Heat and Heat-Engines: A Study of the Principles Which Underlie the Mechanical Engineering of a Power Plant
The effort has been made under another title, "The Mechanical Engineering of Power Plants," to discuss the steam-engine and the steam-boiler with their accessory apparatus, so as to enable students and others to make an intelligent selection of successful designs for a set of conditions which might be imposed. The object of the author was to make the reader familiar with accepted solutions of the power-house problem in all its details, but no attempt was made to discuss the questions of design of such apparatus. It was intended that the student should ask at the end of his study of that book: What are the principles of physics and dynamics upon which these machines depend; and how do engineers proceed when called upon to design such powerhouse engines?
This book, under the title of "Heat and Heat-engines," has been prepared to answer these questions in part. It discusses the energy resident in fuels, and the methods of its liberation as heat for power purposes; the transfer of such heat to convenient media whereby it can be used in heat-engines; the laws and properties of such media, and the design of cylinders of the necessary volume to give a desired mechanical effect or horse-power.
