Abstract
A system for improving steam integration of a combined cycle (CC) power plant. A heat recovery steam generator (HRSG) receives exhaust gases from a gas turbine and discharges steam to a steam turbine. A dual reboiler arrangement includes a first reboiler and a second reboiler, the first reboiler receiving steam discharged from the steam turbine and using heat extracted from the received steam to heat a solvent circulated by a carbon capture arrangement, and the second reboiler channeling steam into the first reboiler for use in heating. A steam ejector receives an external flow, and mixes the external flow with steam from the steam turbine. A flash drum recovers excess steam from the first reboiler and discharges a portion of the recovered excess steam to a steam cycle arrangement including the HRSG and the steam turbine.
