Language: English . Brand New Book ***** Print on Demand *****. Excerpt from Minutes of Proceedings of the Institution of Civil Engineers, Vol. 122: With Other Selected and Abstracted Papers As early as forty years ago, Cornish boilers capable of evapo rating 10 lbs. Of water per lb. Of Welsh steam coal were made, and were used for supplying steam to Cornish pumping-engines, producing one i.hp. Per hour with a consumption of 1 8 lb. Of Welsh coal, at a boiler-pressure not exceeding 40 lbs. Per square inch. The weight of steam per i.hp. Per hour does not always represent the true economy of the engine, because it may be that, in order to secure the highest economy, the size, friction, first cost, and cost of maintenance of the engine have been largely increased. Compound Cornish engines were constructed as early as 1845, but it was found that with the boiler-pressure then available, viz., 40 lbs. Per square inch, no better duty was obtained from them than from the single-cylinder engines. The compound engine became a success when higher boiler-pressure and therefore greater ranges of expansion became practicable, and the triple-expansion engine succeeded the compound engine in the same way. There are well-known practical reasons for increasing the number of cylinders at higher pressures and greater ranges of expansion. In order to determine the relative efficiencies of different types of engines it is necessary to have a standard of comparison. The efiiciency of a steam-engine may be expressed by the number of units of heat expended to develop a given quantity of work, but in practice such a statement afi ords no measure of the quality of the machine as a steam-engine, because in it the conditions under which the engine works are not considered. Higher pressure and greater range of expansion produce greater economy, other things being equal. Therefore, in comparing the construction of one steam-engine with that of another, a basis of comparison must be established which will show how the other conditions vary if they are not equal, and it is with the Object of drawing such a com parison that the Paper has been prepared.
