The importance of effecting the greatest possible improvement in the economy with which the national fuel-resources are ~J utilized will be apparent when it is considered that under existing conditions, and with the demands increasing at the rate they have since active coal-mining first became an established industry, the present estimated coal-reserve, about 2,000 billion tons, will have been absorbed before the end of the next century. The yearly consumption is now 500,000,000 tons and it is increasing at the rate of doubling itself every ten years. Of the total amount mined, so far, due to exacting requirements with regard to the quality of the marketable fuel, and due to wasteful methods of mining it, there has been left in the ground, inaccessible for future use, or wasted as unmarketable product, an amount even greater than that actually rendered useful. The portion of the fuel consumed for industrial purposes, for generating power, or for metallurgical use, which is by far, the I greater portion of the fuel actually rendered useful, has, according to modern standards, been utilized particularly inefficiently; but a tendency toward a strict reform in this respect is afoot, and the Jproblem at present is how to utilize, not only the energy in the good grades of fuel to the greatest possible extent, but also to find new ways for an effective utilization of inferior grades hitherto wasted. The gas-engine is looked upon as a means for effecting reform in the one respect as well as in the other, and, although the final development of the engine has probably not as yet been seen, its theory indicates at present how far an increased economy may be hoped for, just as the steam-engine theory, in the days of Watt, indicated the final limit for efficiency of the steam-engine cycle, toward which the actual performance of the engine has gradually, by steps, approac(Typographical errors above are due to OCR software and don't occur in the book.)

This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1914 Excerpt: ... one twin engine of the same cylinder dimensions, rated at no B.H.P. The maximum indicated horse-power is, on producer gas, respectively, 70 and 140. Both units are direct connected to directcurrent generators, and run 200 revolutions per minute. The fly-wheels are 8'--6" outside diameter and their mean radius of the rim is 3.9 feet. The weight of the wheel for the twin-engine is 11,500 lbs. Its weight reduced to the mean rad. of the rim 9,900 lbs. The armature wgt. redd. to the "mean rad. of the rim 1,600 lbs. Total wgt. redd. to the mean rad. of the rim 11,500 lbs. The corresponding weight for the single engine is 12,100 lbs. Inserting the various values in formula 106, using, in the case of the twin engine,/= 1.04 and, in the case of the single engine, / = 2.4, and solving for K we obtain: In the case of the twin engine, K = 100, and in the case of the single engine K = 90. The current furnished by these engines produces, under all conditions, a very satisfactory light, both when the engines run singly or in parallel. The values of the coefficient K, from 90 to 120, as quoted in Table XXI, for services such as the above, can, therefore, be considered fully conservative. Example.--The installation of three "Snow" four-cycle double-acting, twin-tandem engines at the Gas and Electric Light Co.,s station in San Francisco, which operate alternatingcurrent generators very successfully in parallel, may be used as an illustration for the computation of heavy wheels. The engines are of the following general specifications: Four double-acting cylinders, 42 X 60. Power, 4,000 rated B.H.P., or 5,400 maximum I.H.P. The fly-wheel, 23 feet outside diameter; mean radius 11 feet. Its weight, 97,000 pounds, and it makes 88 revolutions per minute. The g...

This book was originally published prior to 1923, and represents a reproduction of an important historical work, maintaining the same format as the original work. While some publishers have opted to apply OCR (optical character recognition) technology to the process, we believe this leads to sub-optimal results (frequent typographical errors, strange characters and confusing formatting) and does not adequately preserve the historical character of the original artifact. We believe this work is culturally important in its original archival form. While we strive to adequately clean and digitally enhance the original work, there are occasionally instances where imperfections such as blurred or missing pages, poor pictures or errant marks may have been introduced due to either the quality of the original work or the scanning process itself. Despite these occasional imperfections, we have brought it back into print as part of our ongoing global book preservation commitment, providing customers with access to the best possible historical reprints. We appreciate your understanding of these occasional imperfections, and sincerely hope you enjoy seeing the book in a format as close as possible to that intended by the original publisher.

Excerpt from The Modern Gas-Engine and the Gas-Producer In order to acquire a working knowledge of the subject, the general types of gas-engines in successful operation at present should be studied, in connection with the general laws on which their design and operation must be based, because from these types, according to the laws of evolution, there naturally will be developed the successful types of the future. Chapter XIV is devoted to this branch of the subject, and the author here takes occasion to express his appreciation of the generosity with which engine-builders have placed illustrations and information at his disposal.
