With a surface condenser, the cooling water and condensate are typically pumped to the cooling tower in separate streams. Some plants use surface condensers where the latent heat from the condensing steam is transferred to cooling water being circulated through the condenser tubes. In a barometric condenser, the cooling water is sprayed directly into the steam, with the cooling water and condensate being pumped to a cooling tower where the condensing heat load is rejected to the ambient. The steam discharges to a condenser where it is condensed at a subatmospheric pressure (typically a few inches of Hg). 1-Schematic diagram of a dry-steam power plant. Normally, a condensing turbine is used however, in some instances, a backpressure turbine is used that exhausts steam directly to the ambient. Mitigation of corrosive substances contained in the process stream (typically removed with treated water washing) may be required. Before the steam enters the turbine, appropriate measures are taken such as steam separators or scubbers upstream of the turbine to remove any liquids or solid debris from the steam flow. If the steam at the wellhead is saturated, steps are taken to remove any liquid that is present or forms prior to the steam entering the turbine. The stream is most oftern saturated as produced. It would be unusual to see superheated steam from the source as it arrives at surface. When the geothermal resource produces a saturated or superheated vapor, the steam is collected from the production wells and sent to a conventional steam turbine (see Fig.
