Abstract:
A method for operating a gas turbogenerator set, said gas turbogenerator set comprising a compressor unit, at least one combustion chamber, at least one gas turbine and one generator, said method comprising the steps of: operating the gas turbogenerator set to produce an exhaust gas stream; dividing the exhaust gas stream from the turbine into at least two part streams routed in parallel; directing a first part stream of said two part streams to flow through a recuperator, directing a second part stream of said two part streams to flow through a steam generator, thereby generating high-grade superheated steam in said steam generator; conducting compressed combustion air through a secondary flow path of said recuperator and introducing the steam obtained from the steam generator downstream from the recuperator secondary flow path into the compressed combustion air which has previously been heat treated in the recuperator.
