2.3.4.1 Direct Dry Steam Plants

Оглавление

Direct dry steam geothermal power plant uses steam which is at 150 °C or higher, produced from the production well, to generate electricity with the help of geothermal steam turbines. Owing to design, these turbines effectively use the low‐pressure and high‐volume fluid produced in the steam field for conversion. Usually, these plants make use of condensing turbines, and thus produced condensate is re‐injected (closed cycle) or evaporated in wet cooling towers (https://iea‐etsap.org). The power generation capacity of these plants lies between 8 and 140 MW (www.platts.com).
