  "textContent": "A combined cycle power plant (2) includes a gas turbomachine (4), a steam turbomachine (18) operatively coupled to the gas turbomachine (4), and a heat recovery steam generator (37) operatively coupled to the gas turbomachine (4) and the steam turbomachine (18). The heat recovery steam generator (37) includes a high pressure reheat (42) section provided with at least one high pressure superheater (41) and at least one reheater (42). The combined cycle power plant (2) further includes a controller operatively connected to the gas turbomachine (4), the steam turbomachine and the heat recovery steam generator (37). The controller is selectively activated to initiate a flow of steam through the heat recovery steam generator (37) following shutdown of the gas turbomachine (4) to lower a temperature of at least one of the high pressure superheater (41) and the at least one reheater (42) and reduce development of condensate quench effects during HRSG purge of a combined cycle power plant (2) shutdown.",
