Not illustrated. 1903 Excerpt: ...American Co.'s underfed stokers, which have given great satisfaction. The ashes are sluiced to an elevator and finally dumped on the prairie adjoining the boiler-house. From the cars on a track in front of the boiler-house, the coal is dumped into large bins, from which a bucket elevator takes it into the supply bins suspended in front of the boilers. The coal drops from these bins to the feed-hoppers and is taken by the grates automatically and continuously. The feed-water is handled by two large Knowles pumps, each of sufficient capacity to supply all of the boilers alone. The water is taken from the hot well of the condenser and is delivered by the pumps through the Green heater to the boilers and acquires in this way a temperature of about 2000 F. Twelve men are employed in the boiler-house. The engine-and dynamo-room (see Fig. 40) contains a Corliss engine of about 800 H.P., a Westinghouse compound engine of 400 H.P., and two triple-expansion engines of 900 H.P. each. The two last-named engines are directly coupled to two dynamos each. This makes a total of about 3000 H.P. The Corliss engine runs the dynamos of the old section of the refinery at present by means of belting and shafting. The current for the electrolytic work is supplied by two 220 kw. Westinghouse generators, belt driven, and five 270 kw. Westinghouse generators, one of which is belt driven, while the other four are directly connected to the two triple-expansion engines. This makes altogether 1790 kw., corresponding to 2560 H.P. Out of this total, one generator together with the 400 H.P. engine are kept in reserve, being an electrical unit of 220 kw., equivalent to 315 H.P. This reserve unit can be switched over to any one of six circuits in case of an accident or repairs to any of the ...
