Patent ID: 8166747

Claim:
A gas turbine engine system comprising in operating series: a compressor system for compressing a working fluid; a combustor downstream of the compressor system; a turbine system downstream of the combustor; an exhaust flue; vapour generating means downstream of the turbine having a first operating side for containment of the working fluid and a second operating side for containment of a liquid fluid to be vapourised in the vapour generating means by heat transfer with the working fluid, wherein the vapour generating means has a dry-run capability such that the turbine exhaust passes through the first operating side without a fluid to be vapourised passing through the second operating side; a bypass damper downstream of the first operating side of the vapour generating means; and a condenser for condensing condensable fluid from the working fluid, wherein the bypass damper is switchable between a first operating position, where the working fluid is directed to a bypass conduit which bypasses the condenser before joining the exhaust flue, and a second operating position where the working fluid passes through the condenser to the exhaust flue.
