๐ Calculation Methodology & Supercritical ORC Standards
Supercritical Heat Addition Advantage
Heating above the critical pressure ($P > P_{crit}$) eliminates the isothermal phase change plateau, allowing the working fluid temperature to glide continuously with the heat source profile.
Internal Recuperation (IHX)
Dry organic vapors exit the expander with significant superheat. The recuperator transfers this waste heat to preheat the high-pressure liquid before entering the vapor generator.
Key Engineering Assumptions
- Supercritical heating without boiling pinch-point limitations.
- Dry expansion avoiding liquid droplet erosion in turbine blades.
- Applicable to geothermal brine, biomass, solar thermal CSP, and engine waste heat.
