Solar thermal power plant comprising a solar collection system and a steam-electric power plant and a method for power generation

摘要

A solar thermal power plant is provided comprising a solar collection system and a steam-electric power plant. The solar collection system comprises one or more tube radiation absorbers containing a thermal fluid therewithin, the system being configured to heat the thermal fluid by passing the thermal fluid through the one or more tube radiation absorbers while the absorbers are irradiated with solar radiation. The steam-electric power plant comprises an intermediate-pressure steam turbine, a low-pressure steam turbine, at least one additional steam turbine having an inlet pressure higher than that of the intermediate-pressure steam turbine, and piping containing a working fluid. Each turbine is associated with a heat exchange system adapted to transfer heat from the thermal fluid to the working fluid.
