Research output: Patent

Abstract

A rotary pressure-exchanger acting as a prime mover, or ''gas-wave turbine'', has a high-pressure scavenging stage (28 and 47) that supplies compressed air to a combustion chamber (25) and receives compressed hot gas from it. Part of the expanding hot gas is supplied to an intermediate-pressure scavenging stage that supplies compressed air to a high-pressure pre-scavenge inlet (24) and optionally also to low-pressure pre-scavenge inlets (19 and 32). Low pressure scavenging steps (11 and 34, 21 and 45), alternate with scavenging steps at higher pressures.
