Abstract

See full text

An apparatus comprises an expander comprising a member moveable within a chamber in response to an expanding gas. A linkage is in communication with the member and configured to transmit out of the chamber, a power of the expanding gas. An element effects gas-liquid heat exchange with the expanding gas. The apparatus is configurable in a first mode of operation in which the member moves in response to the expanding gas as a result of combustion within the chamber, and in a second mode of operation in which the member moves in response to the expanding gas in an absence of combustion within the chamber. Also disclosed is a turbomachine where working fluid and plenum are rotated together, reducing losses from velocity shear. Further disclosed is a turbine comprising a nozzle on a rotatable member, where linear velocity of expanding gas from the nozzle substantially matches member rotational velocity.
