ABSTRACT:
A heat recovery method is disclosed suitable for combined gas turbine/steam turbine cycles including at the exhaust of a gas turbine a waste heat boiler in which water is first treated in a degassing unit connected to a first evaporator and comprising a certain number of heat exchangers. The boiler uses an ultrasupercritical steam cycle with four pressure levels with subcritical fluid intermediate evaporator stages.
