Abstract
A steam injection gas turbine engine having a once-through steam generator (OTSG). A condenser is provided downstream of the OTSG to capture water and is protected from hot flue gasses during startup by a bypass circuit. Optionally, heating the exhaust downstream of the condenser using coolant taken from an intercooler provides plume suppression.
