• F25J 2240/02 Expansion of a process fluid in a work-extracting turbine (i.e. isentropic expansion), e.g. of the feed stream
• F25J 2240/30 Dynamic liquid or hydraulic expansion with extraction of work, e.g. single phase or two-phase turbine
• F25J 2240/40 Expansion without extracting work, i.e. isenthalpic throttling, e.g. JT valve, regulating valve or venturi, or isentropic nozzle, e.g. Laval
• F25J 2240/60 Expansion by ejector or injector, e.g. "Gasstrahlpumpe", "venturi mixing", "jet pumps"
• F25J 2240/70 Steam turbine, e.g. used in a Rankine cycle
• F25J 2240/80 Hot exhaust gas turbine combustion engine
• F25J 2240/90 Hot gas waste turbine of an indirect heated gas for power generation
