Excerpt from Illustrated Catalogue of Buffalo Mechanical Draft Apparatus: Induced and Forced Applications of Mechanical Draft to Central Power Stations in Street Railway, Electric Light, Steamship Plants and Industrial Works, With Illustrations of Suitable Fan Types<br><br>Any system of figuring costs brings the owner's close attention to the coal pile, and the increasing smoke nuisance has likewise engaged the eye of the public, resulting in the enforcement of smoke ordinances.<br><br>From all these causes, it is natural that men should look for some improvement in the method of pro duction as well as utilization of power. The tubular boiler has superseded the original plain tank of boiling water. And the water-tube boiler is a later addition, the object being the more rapid production of steam, and to secure the maximum heating effect from the coal consumed. To this end, various draft-improving and regulating devices have also been put on the market, first as supplementary to, and later as improved substitutes for, the chimney. One of the first of these, and the one which best satisfied all requirements, was the fan.<br><br>Stating briefly the considerations which have led to the use of the fan for mechanical draft, they are: first cost; economy in operation under any load, light or heavy, within the capacity of the boiler; increased efficiency in steam generated per pound of fuel; close automatic regulation of steam pressure carried on the boiler; and adaptability in form and proportions to use any available space. These desirable points, with additional features, will be considered more in detail in the following pages.<br><br>This catalogue also contains cuts showing various types of Buffalo Mechanical Draft Fans, and engines for driving them, with illustrations from photographs of installations in operation. The tabulated data also given will be found of service in obtaining general information on the various points of application. The services of our engineering department are at all times at the command of prospective customers, who will thus receive the benefit of our experience dating back to the first use of mechanical draft, and the special apparatus which is often required for the economic use of the cheapest fuel in that locality.<br><br>About the Publisher<br><br>Forgotten Books publishes hundreds of thousands of rare and classic books.
