Abstract: An economizer in a solar tower plant and operating method of said plant the purpose whereof is to make use of the heat from the heat losses generated around the solar tower receivers (3) to preheat the fluid with which the saturated steam or superheated steam solar receivers are fed. When the heat from the losses absorbed by the economizer (2) is not sufficient to achieve the necessary minimum temperature, a secondary economizer (4) is used which takes live steam (prior to it entering the turbine) and increases the temperature of the feed water of the receiver (3).

Abstract: Method of operating a solar thermoelectric power plant that allows operation of high-, medium- and low-pressure superheating turbines with both superheated steam and saturated steam. The plant includes energy storage in high-pressure liquid tanks. The method described allows the direct introduction of saturated steam into a superheated steam turbine. This steam may receive an intermediate reheating between the high-pressure turbine and the low- and medium-pressure turbines to achieve conditions of superheated steam. The mode of operation proposed in the invention facilitates the operation of the plant in periods without sunshine (during transient periods, such as passing clouds or night time) or during discharge of accumulators (saturated liquid tanks at high-pressure).

Abstract: Superheated steam tower receiver with a well-defined configuration that benefits the transfer of heat between the surface of the component and the working fluid. Composed of at least four subpanels that define the circulation circuit for the steam by means of internal passages. The component is provided with saturated steam and for the production of said steam it is possible to use other solar concentrator technology. The proposed configuration minimizes the technological risks inherent in superheated steam receiver technology where drawbacks arise in the structure of the material owing to the thermal cycles to which the solar component is subjected.

Abstract: The invention relates to a configuration of the receivers in concentrated solar plants with towers comprising at least one medium-temperature receiver (3) and one high-temperature receiver (4) in which each high-temperature receiver (4) is located above and slightly in front of each medium-temperature receiver (3), such that a portion of the rays that bounce off the medium-temperature receiver (3) heats the rear portion of the high-temperature receiver (4) and in which the high-temperature receiver (4) is positioned such that the majority of the surface thereof is opposite the wall of the cavity (2), only the bottom portion of the receiver (4) remaining free.

Abstract: A receiver with a configuration of saturated and superheated steam solar modules in a tower solar concentration power plant. The configuration allows the incidence of radiation on both sides of the superheated steam module, providing significant benefits for its durability and global control of the power plant.
