Steam turbine – Wikipedia

  • A steam turbine is a device that extracts thermal energy from pressurized steam and uses it to do mechanical work on a rotating output shaft. Its modern manifestation was invented by Charles Parsons in 1884. The steam turbine is a form of heat engine that derives much of its improvement in thermodynamic efficiency from the use of multiple stages in the expansion of the steam, which results in a closer approach to the ideal reversible expansion process. Because the turbine generates rotary motion

        Steam Turbine – Oxygen Not Included Wiki

        • The steam below the generator must be at least 125 °C. If the steam below the generator becomes less than 125 °C the Steam Turbine will cease to produce any power.Additionally, the steam turbine itself must be kept below 100 °C. If its temperature gets higher than 100 °C, the warning message \"Turbine too hot\" will appear, and steam will bypass the turbine. This can be especially problematic if you are trying to maintain a hydrogen atmosphere around the turbine. In some cases, enough water wil…
