Sourcebook on the production of electricity from geothermal energy

“…2 is shown in figure 10.24. A simplified plant schematic/hent balance diagram is given in figure 10.26 [Akiba, 1970;Mercado, 19763. The condenser is of the barometric, direct-contact type and is located next to the power house. Noncondensable gases are removed from the top of the condenser shell through a gas extraction system consisting of a 2-stage steam ejector with inter-and after-condensers.…”
