Power Generation Calculator

Calculating Steam Turbine Power Given Steam Conditions and Flow

To calculate your power generation potential, click on the following link and follow the instructions below:

  1. Set “Solve For” drop-down to Outlet Properties

  2. For Inlet Steam section:

    • Enter Inlet Pressure (PSIG)

    • Enter Inlet Temperature (°F)

  3. For Turbine Properties section:

    • “Selected Turbine Property” drop-down to Mass Flow

    • Enter Steam Mass Flow (klb/hr [e.g. 10,000 lbm/hr = 10.0 klbm/hr])

    • Enter assumed isentropic efficiency (see Table below). To choose the "Turbine Type", please visit our Products Page for more information.

    • Enter assumed generator efficiency of 93% (takes gearbox losses into account)

  4. For Outlet Steam section:

    • Enter desired Exhaust Pressure (PSIG). In case of condensing exhaust, -12.7354 must be entered in this section.

  5. Hit "Enter" and see your power generation potential in the "Power Out" section. Note the Outlet Steam Pressure and Temperature in addition to the Power Output and compare it with the 'Operating Parameters' listed in the Products Page to finally arrive at the best turbine for your needs. ​

Note: Isentropic efficiencies of Steam Turbines can range from 20-90%. The efficiencies in the Table are simplified values for the purpose of estimation only. For accurate performance values please contact the team at NCON.
