Excerpt from Steam Boilers, Engines and Turbines
In the following pages the author has endeavoured to set forth the principles and practice of steam, as they are understood by modern engineers, for the use of the student, using the term in its wide sense, viz. to include all those to whom a knowledge of steam and of steam-using apparatus will be of service. With the universal employment of power, a knowledge of the properties of steam is becoming daily of more and more importance to engineers of all branches, and to large numbers of business men and others who are not directly engaged in the practical application of steam appliances.
The author has endeavoured to set out, in simple language, and with the aid of only the very simplest forms of mathematics, the properties of water, of steam, of air, and of the gases that enter into the process of combustion, and he has also endeavoured to give a resume of the latest practice in steam, and a description of the latest appliances for its economical generation and use. With the ever-increasing demands for power, and with the repeated warnings from scientists of the possible shortness of coal, and again with the steadily increasing cost of mining coal in the United Kingdom, sources of economy in the use of steam, it has appeared to the author, are of increasing importance; and he has endeavoured to give a clear and simple explanation of the different apparatus designed to produce economy, and of the leading forms on the market.
The book is divided into six chapters. In the first chapter the author has dealt with the underlying principles upon which the use of steam apparatus is based. In the second chapter he has described the principles and construction, and, as far as space has allowed, the working of the different forms of boilers on the market.
