SOLAR THERMAL POWER SYSTEM

摘要

A solar thermal power system includes a solar receiver for heating thermal energy storage fluid and be stored and utilised from a thermal energy storage arrangement having hot and cold storage tanks. The system includes a steam generator arrangement, which utilises the heat of the thermal energy storage fluid to produces steam to run a turbine. The arrangement includes a bypass line configured to bypass the hot storage tank from the steam generator arrangement, and to supply the hot thermal energy storage fluid from the solar receiver directly to the steam generator arrangement, during day times, when the solar receiver the steam generator arrangement are both in operating mode, thereby recovering stored potential energy available in the down corner hot thermal energy storage fluid from the solar receiver.

1. A solar thermal power system, comprising:
a solar receiver configured to heat thermal energy storage fluid; a thermal energy storage arrangement comprising
a hot storage tank configured to receive and store the hot thermal energy storage fluid from the solar receiver, anda cold storage tank configured to receive and supply the cold thermal energy storage to the solar receiver to be reheated; a steam generator arrangement comprising at least an economizer section, an evaporator section, a superheater section and a reheat section communicably configured to utilize the heat of the hot thermal energy storage fluid from the hot storage tank to generate and supply the steam to a steam turbine; and a bypass line configured to bypass the hot storage tank, and to supply the hot thermal energy storage fluid directly from the solar receiver to the steam generator arrangement, during day times, when the solar receiver the steam generator arrangement are both in operating mode, thereby recovering stored potential energy available in the down corner hot thermal energy storage fluid from the solar receiver.
