Abstract

Power is generated from heat from a source such as geothermal brine or the cooling system and exhaust of an internal combustion engine. The heat is used to boil a non-aqueous working fluid by heat exchange in a boiler. Wet vapour from the boiler is fed by a line (22) to a positive displacement twin-screw expander (23). The expanded fluid is fed by a line (15) to a condenser (17) from which it is returned by a feed pump F to the boiler. The flow rate through the boiler and expander is controlled by a controller (33) responsive to pressure and temperature sensors monitoring a tapped-off throttled sample flow through a chamber (30) to control the dryness of the fluid in the line (22). Lubricant for the expander may be included in the liquid phase.
