A good illustration ofthis arrangement is offered by the turbineplant at Elyria, Ohio, shown in Fig. 13 andaccompanying views. The cross-hatchedareas represent the sections of the concretewalls constituting the foundation piers. Theexhaust extends straight downward into thecondenser, which, as shown, is located be-tween the piers. This vertical exhaust leg is of sufficient lengthto accommodate a fluted copper expansion joint, a free exhaustbranch to atmosphere and a gate valve. 2000-KW.
