TURBINE-CONDENSER SUPPORT SYSTEM ABSTRACT OF THE DISCLOSURE A subatmospheric pressure condenser has an en- closure within which steam is condensed after exhausting from an associated turbine. The enclosure is flexibly con- nected to the turbine to permit relative movement there- between. The condenser also has an outer wall which is flexibly connected to the enclosure to define a vacuum balancing chamber therebetween with the outer wall being structurally connected to the turbine for the purpose of reducing the atmospheric pressure force exerted on the turbine's structure by the turbine. The structural connec- tors between the outer wall and the turbine intersect the enclosure and provide fluid communication therethrough between the turbine's exhaust port and the vacuum balancing chamber. At the intersection between the structural con- nectors and the enclosure, sleeves are attached to the enclosure in closely spaced surrounding relationship with each of the structural connectors to minimize liquid intru- sion therebetween from the enclosure to the vacuum balancing chamber. Since the outer wall is flexibly connected to the enclosure and the vacuum balancing chamber has little or no water intrusion, the outer wall efficiently transmits atmos- pheric pressure forces exerted thereon through the struc- tural connectors to the turbine and reduce the load on and thus the required size of the turbine's support structure. The sleeve members which fit about the structural connectors permit relative movement therebetween and extend a prede- termined distance from the enclosure to further minimize -1- water leakage into and subsequent accumulation thereof in the vacuum balancing chamber.
