Abstract

188,658. Marguerre, F., and Hausmann, M. Nov. 11, 1921, [Convention date]. Addition to 167,763. Power-generating systems.-In apparatus for storing and utilizing excess energy as described in the parent Specification, water is evaporated and steam is condensed in chambers separate from the storage chambers. Direct contact condensers or evaporators Cu, Co, Fig. 1, are connected to the low and high temperature storage chambers a, b by pipe systems in which are arranged pumps Pu, Po, and valves U1 - - U4 and O1 - - 04. When the turbine h is in operation, the valves U1, U4 are open and the valves U2, U3 are closed, water being drawn from the chamber a by the pump Pu and passed into the chamber Cu, where it is brought into contact with exhaust steam from the turbine. At the same time, the valves 01, 04 are open and the valves 02, 03 are closed, hot water being drawn from the chamber band evaporated in the chamber Co. During the operation of the compressor g, the valves are reversed, and water is evaporated in the chamber Cu and steam condensed in the chamber Co. In a modification, lye is used in place of water in the lowtemperature chamber NaHo, Fig. 2, and the separate, evaporating and condensing chambers are replaced by tubular apparatus Co of the form of a surface condenser. During the working of the turbine, water from the chamber H2o is passed through the tubes of the tubular apparatus and lye from the chamber NaHo is passed over the tubes in contact with the exhaust steam from the turbine. During the working of the compressor, diluted lye from the upper part of the chamber NaHo is passed into the tubular apparatus through a pipe l1, steam being drawn off through a pipe c and forced through a pipe d directly into the tubes of the tubular apparatus.
