The installation was designed to serve a streetrailway, an electric light and power company and a manu-facturing concern and the test was made to settle a con-troversy as to the proportionate amounts of power and offuel to be charged to each of the three accounts. The steam generating equipment includes six Wickesboilers, hand fired, arranged in three batteries of two boil-ers each and served by three steam feed pumps and ablower, forced draft being necessary with the grade of coal. 10 11 12 1 2 3 4 5 0 7 s 9 10 u 12DIAGRAM SHOWING RAILWAY LOAD used. One 13-in. main carries the steam to the engines atthe power house and one 14-in. pipe is utilized to conductthe exhaust steam to the apparatus of the manufacturingcompany which is also directly supplied with live steam byone 6-in. and one 4-in. main. In the manufacturing plant,which is located some 400 ft. from the boiler house andabout the same distance from the power house, the exhauststeam is utilized for the evaporation of brine in the manu-facture of salt. The conditions are such that all of the exhaust steam produced in the power plant can be utilizedas produced, irrespective of the character of the power plantload curve. Such additional steam as is required at anyperiod of the day in the manufacture of salt, is obtaineddirectly from the boiler plant as live steam. The powerplant proper is equipped with three direct-connected hori-zontal units consisting of a pair of simple non-c
