Each engine unit has a jet condenser of Dean manufac-ture, with its auxiliaries located in the basement betweenthe foundations for the high and low-pressure cylinders. Twofree-exhaust pipes standing on footings near the stack areprovided. Each of the condenser sets has a capacity for 20,000 pounds of exhaust steam per hour with water at 70degrees F. The condensing water is taken direct from a30-inch suction main connected with the supply well, as pre-viously described. The discharge is led through two 12-inchpipes into a 16-inch pipe which connects with the 36-inchdischarge conduit leading to the lake nearby. The con-densers are provided with a forced injection from the low-service pump, for starting. The condenser air pumps can.

It is the scheme of operation to run condensing duringthe summer and non-condensing during the cold utility of this plan of operation is brought about by thenearby demand for steam for heating purposes. The WinonaAssembly is now a purchaser of steam, connected to a largeamount of radiating surface, for which a rate of 30 centsper square foot per season is paid. The exciters comprise an Allis-Chalmers 50-kilowatt6-pole 120-volt generator direct connected to a Ball high-speed engine taking steam from the 4-inch high-pressureauxiliary header, and a 4-pole 50-kilowatt 120-volt Allis-Chalmers generator driven at 720 revolutions per minute bya Bullock 3-phase 25-cycle 375-volt induction motor mountedon the same bedplate. This unit is operated by currenttaken from the high-tension busbars and stepped down by aseparate installation
