Abstract:
A combined cycle system has a gas turbine for generating an exhaust gas stream and a heat recovery steam generator with a housing for defining a horizontal exhaust gas flow path for the exhaust gas stream. Positioned within the housing is a heat recovery assembly having vertical rows of horizontally oriented heat transfer tubes transverse to the direction of gas flow and spaced apart in the direction of the gas flow path. The heat transfer tubes are supported by a plurality of vertical support plate assemblies oriented parallel to the exhaust flow path. Each support plate assembly has a plurality of coplanar support plate segments, each support plate segment supporting less than three rows of heat transfer tubes.
