Excerpt from Mechanical Draft: A Practical TreatiseThe subject of mechanical draft has been discussed at greater or less length in the technical press and before various engineering societies, but in all cases such discus sion has been distinctly limited. Here, for the first time, the attempt is made to give the treatment that its importance demands. Although its introduction is evidence of a somewhat radical departure in certain features of boiler practice, yet extended and recent experience clearly indicates the permanence of this departure. Hereafter, the progressive engineer will not adopt the chimney as the sole means of draft produc tion, but will first carefully consider the respective advantages of the chimney and the fan, for the claims of the latter to superiority cannot be disregarded.Manifestly, the individual who in the present day is to decide between the two methods, requires a clear presentation of their respective merits, such as is attempted in this work. Its object is two-fold: First, to instruct by a lucid discussion of the entire subject, with such supplementary information as may be necessary to show the superiority of mechanical draft. Second, to show the special adaptability of the Sturtevant fans for this purpose, and to indicate in some degree the extent to which they have already been applied.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
