Embodiment Construction

[0039] figure 1 The structure and the cycle of a solar thermal plant installation 1 with direct vaporization according to the invention are schematically shown. The plant 1 comprises a solar harvesting field 2 in which sunlight is collected and converted into heat energy and may for example have parabolic trough collectors, solar towers, parabolic mirrors or Fresnel collectors. The collected sunlight is delivered to the heat transfer medium, which is vaporized and introduced as a working fluid through the live steam line 10 into the expansion section 19 , which for example consists of the steam turbine 3 . The steam turbine 3 includes a high-pressure turbine 4 and a low-pressure turbine 5 , which drive a generator 6 . The working fluid is expanded in the steam turbine 3 and subsequently liquefied in the condenser 7 . The feed water pump 8 pumps the liquefied heat transfer medium back into the solar collector field 2 , thus closing the heat transfer medium or working fluid ci...

Abstract

The invention relates to a solar-thermal power plant (1), comprising a working fluid circuit (9), a solar steam generator based on direct evaporation, and a steam turbine (3) for relieving the workingfluid on a relief path (19) while supplying technical work, comprising at least one intermediate superheater, which can be heated by means of working fluid that can be removed from the circuit (9) upstream of the intermediate superheater and superheated by means of the working fluid thereof, which can be fed downstream of the heating removal by flowing into the relief path (19). The invention further relates to a method for operating such a plant.

Description

technical field [0001] The invention relates to a method for operating a solar thermal power plant in which a working fluid circulates in a cycle comprising a solar boiler based on direct vaporization and a steam turbine in which the working fluid is expanding Section expansion to output technical work, also includes at least one intermediate reheater, which is heated by means of working fluid drawn from the cycle upstream of the intermediate reheater, and the working fluid reheats said at least one intermediate reheater, working fluid The expansion section may be fed into the expansion section downstream of the heated withdrawal point via an inflow device. Background technique [0002] Solar thermal power plant is another kind of power generation device that is different from traditional ones. Solar thermal plants use the sun's radiant energy to produce electricity. It consists of a solar power plant section for absorbing solar energy and a second mostly conventional powe...
