In the northeast corner, adjacent to the steelfurnaces, are located the foundry, machine shop and various shops and buildings for the construction and maintenance ofthe plant. The general scheme of power supply for such a large steel plantis one requiring a comprehensive treatment of the problems involved,which are not only of an engineering, but economical nature aswell. As in the lajout of the buildings and of the equipment, suchmethods and apparatus are adopted as will result in the lowest oper-ating consistent with the least investment. The predominat-ing principle, however, considered in the operation of the plant is thatof certainty of operation, and the design consequently is affected tothat extent. Economy is nf minor importance, although receiving. FIG. 3.—SW lTCHEO.\RU FOR TR.\NSFER T.\BLE. BESSEMER HULSE. attention wherever possible. As a consequence, the utilization otby-products has affected the problem materially. The installation is of unusual interest, as aflfording a means forthe study of the various motive powers as applied in a steel plantwhich is being erected under the most favorable conditions at thepresent time. The steam engine will be used exclusively for theroughing and blooming mills, as rolling mill service has been heldto be too severe for the electric motor. The gas engine, not beingreadily reversible, is not available for this class of work. The steamengines will be run condensing, a practice not heretofore adoptedin this country, although triple-expansion condensing engines arein use in such service in Europe. Gas engines of and 2,000 hp,utilizing blast furnace gas, are employed to drive the blower enginesof the blast furnaces. Although engines of the same type, but smallercapac
