This app enables you to quickly estimate the electrical power generated by a single flash geothermal power plant. It uses steam tables for fluid properties and isentropic efficiency for turbine genset power output.
The single flash process has four steps, well, separation, turbine inlet and outlet. Water as saturated liquid at a certain temperature and pressure is reduced to the flash temperature. After pressure reduction (flashing) the water/steam mixture is separated in the separator where the saturated steam is directed to a turbine and the water/brine is redirected to the injection well. The steam propels a turbine which generates electricity.
Inputs are entered using two buttons, one for well inputs and one for flashing and turbine properties:
1) Well: brine flow and temperature, the app calculates the corresponding pressure
2) Turbine: turbine inlet temperature (separation temperature), genset (turbine + generator) efficiency and turbine outlet temperature.
The main output is the electrical power generated, additional outputs are pressure, temperature and mass flow values at the relevant process points, i.e. well, injection, turbine inlet and outlet.
Currently the app only accepts integers as inputs and it is up to the user to make sure the quality of the input data makes sense. There is no correction function if e.g. the user should enter a turbine outlet temperature higher than turbine inlet temperature.
The app is not intended to replace due diligence or proper plant design, it is a simple calculation tool which could be useful for a first step in e.g. a feasibility study.
