[Vol. XXIII. No. 5. is clearly shown in the plan reproduced herewith. As in thecase of the engine plant each unit is equipped with an inde-pendent condenser, but the circulating water and other pumpsare used in common by both units. A striking feature of theinstallation is the foundations. In the plan the two turbinefoundations have been sectioned at different levels to showthe area required for supporting the dead weight of the tur-bines. The foundations consist of concrete walls, slightly bat-tered and varying in thickness from 17 ins. to 21 ins., and ap-proximately 12 ft. 9 ins. in height. A heavy concrete plate,resting upon a bed of hard-pan, constitutes the foundation foot-ing. The openings in the foundation walls accommodating. HotWater Pumps TURBINE CONDENSING APPARATUS side, which will keep the tube in place, and, at the same time,permit it to expand and contract freely. It also makes it possi-ble to remove any tube readily or replace any stuffing box incase of leakage. At the point where the steam enters the con-denser there is a baffle-plate to distribute it and relieve the tubesof its impact. Both condensers have suitable hot wells, withfloats controlling the steam throttle to the pump, which re-moves the condensed steam and delivers it to the main hot well,from which it is returned directly to the boilers. In connection with each condenser there is an air cooler toprecipitate all moisture from the air before it reaches the airor vacuum pumps. This cooler is of the surface type, and is To River
