|Variable Phase Cycle|
The Variable Phase Turbine is a patented, hermetic turbine generator that generates power from two-phase, transcritical, and single-phase expansions. It is the basis for the Variable Phase cycle.
The Variable Phase Turbine shown was operated by flashing liquid nitrogen at -160oC. The measured power agreed closely with that predicted.
Please refer to our technical paper for a more detailed description of the technology and its application to geothermal power production in the Variable Phase cycle. Also, a complete list of Variable Phase Turbine installations and testing experience is included in our two-phase turbine reference document.
