Abstract

In a powerplant comprising in flow sequence a compressor 20, a combustor 22 and a turbine 30a, 30b having a plurality of stages 34. A plurality of turbine stage vanes 36 are positioned prior to the turbine rotor stages 34 and the vanes 36 have passageways 38 therethrough. Steam from a supply means 40 is supplied via a passageway 38 of a least one of the turbine stage vanes 36 to a steam injector 44 for injecting steam into or upstream of the combustor 22. Air is supplied via a valve 48 to the passageways 38 and during the start up period provides the system cooling when steam is not available. Two combustors (222a, 222b), Fig 2, may be provided, each having its own steam (210, 212) and air supplies. A supplementary burner (310), Fig 3 and high pressure boiler (314), low pressure boiler (316) and very low pressure boiler (318) may be provided downstream of the turbine section (330b). <IMAGE>
