Thermal power station combined with a plant for seawater desalination
A combined thermal power station and a desalination plant for seawater are described in which the power station includes a gas turbine set, a waste heat boiler connected to the exhaust gas outlet of the gas turbine and a steam turbine. The waste heat boiler includes first and second sections arranged in cascade on the water side in the flow path of the turbine exhaust gases, the first section in the exhaust gas flow path consituting a steam in the exhaust gas flow path constituting a steam generator for the steam turbine and the second section constituting a source of heat utilized in the desalination plant. Seawater may be passed directly through the second section of the waste heat boiler or high-temperature hot water produced by the second section may be passed through a heat exchanger incorporated in the flow path of the seawater. The waste heat boiler may further include an additional source of heat in the form of a fuel burner for maintaining operation of the steam turbine and desalination plant under emergency conditions in the event the gas turbine set is stopped.
