In this type of power plant, the steam generated by the solar field is fed into the water-steam cycle of the CCPP to increase steam turbine output and reduce carbon dioxide emissions.

Recovery of the condensed steam for reuse as water to feed the boiler closes the water / steam cycle in a thermoelectric station, and as such, the Tejo Power Station was no exception.
33.
KSO uses a superheated steam cycle that should be able to reach a maximum operating temperature of 530 �C . Accumulated saturated steam is also used to provide up to two hours of thermal storage at the plant.
34.
The most efficient thermal system is combined cycle in which a combustion turbine powers a generator using the high temperature combustion gases and then exhausts the cooler combustion gases to generate low pressure steam for conventional steam cycle generation.
35.
Selection of a single-or multiple-pressure steam cycle for a specific application is determined by economic evaluation which considers plant installed cost, fuel cost and quality, plant duty cycle, and operating and maintenance cost.
36.
Although additional energy is required to separate O 2 from N 2, the majority of the energy input can be recovered because the carbonator reaction is exothermic and CO 2 from the calciner can be used to power a steam cycle.
37.
It is the pressurization of the water that circulates through the steam boiler that allows the water to be raised to temperatures well above 100 �C boiling point of water at one atmospheric pressure, and by that means to increase the efficiency of the steam cycle.
38.
In addition to that electrification with renewable energy is much more efficient and therefore leads to a significant reduction in primary energy requirements, because most renewables don't have a steam cycle with high losses ( fossil power plants usually have losses of 40 to 65 % ).
39.
The radioisotope 16 N is the dominant radionuclide in the coolant of pressurised water reactors or boiling water reactors during normal operation, and thus it is a sensitive and immediate indicator of leaks from the primary coolant system to the secondary steam cycle, and is the primary means of detection for such leaks.

In parabolic trough plants, copper is specified in the solar collector field ( power cables, signals, earthing, electrical motors ); steam cycle ( water pumps, condenser fans, cabling to consumption points, control signal and sensors, motors ), electricity generators ( alternator, transformer ), and storage systems ( circulating pumps, cabling to consumption points ).
