Tra gli anelli di imballaggio, servendo così a tenerli in posizione e prevenire la rottura del vuoto. Ogni gruppo motore è dotato di un condensatore a getto di Dean Manufactures-ture, con i suoi ausiliari situati nel seminterrato tra le fondazioni per i cilindri ad alta e bassa pressione. Due tubi di scarico che si trovano sui piedi vicino al catastoforniti. Ciascuno dei gruppi di condensatori ha una capacità di 20,000 libbre di vapore di scarico all'ora con acqua a 70 gradi F. l'acqua di condensazione viene prelevata direttamente da un'aspirazione di 30 pollici m.

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 weather.The 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
