Abstract

Procedimiento para ajustar la presión de un generador de vapor en una central de energía solar.#Se proporciona un procedimiento para ajustar la presión de un generador de vapor. El procedimiento incluye calentar y almacenar fluido de almacenamiento de energía térmica. Además, el fluido almacenado se usa para producir vapor a partir de agua de alimentación, suministrada desde un suministro de agua de alimentación (116) en una disposición de generador de vapor (140). La disposición (140) incluye un economizador (142), un evaporador (144) y un supercalentador (148) configurados de forma comunicable para calentar el agua de alimentación hasta una temperatura saturada para definir la presión de la disposición de generador de vapor (140) y además producir vapor. Además, dependiendo de operaciones de carga completa/parcial, la presión en la disposición de generador de vapor (140) puede ajustarse recirculando el agua de alimentación calentada por la sección de economizador (142) alrededor de la sección de economizador (142) o derivando la sección de economizador (142) mientras que al mismo tiempo se mantienen las temperaturas del fluido en una entrada (144a) del evaporador (144) y en una salida (142b) del economizador (142).Procedure for adjusting the pressure of a steam generator in a solar power plant # A procedure for adjusting the pressure of a steam generator is provided. The procedure includes heating and storing thermal energy storage fluid. In addition, the stored fluid is used to produce steam from feedwater, supplied from a feedwater supply (116) in a steam generator arrangement (140). The arrangement (140) includes an economizer (142), an evaporator (144) and a superheater (148) communicably configured to heat the feed water to a saturated temperature to define the pressure of the steam generator arrangement (140 ) and also produce steam. In addition, depending on full / partial load operations, the pressure in the steam generator arrangement (140) can be adjusted by recirculating the feed water heated by the economizer section (142) around the economizer section (142) or by deriving the economizer section (142) while at the same time maintaining the fluid temperatures at an inlet (144a) of the evaporator (144) and at an outlet (142b) of the economizer (142).
