Solar thermal a steam-generating stage, solar thermal power plant and method for operating a solar a steam-generating stage

摘要

In order to provide a solar thermal a steam-generating stage comprising a solar energy installation, to which by means of solar radiation from a liquid heat transfer medium heat transfer medium-steam can be generated, whereby the solar energy installation a preheater- / evaporator section, and an intermediate superheater region, in which time fluctuations in a field current of liquid heat transfer medium can be compensated for, it is provided, that on the preheater- / evaporator section, at least one buffer means is arranged, which a trap structure for the separation of liquid heat transfer medium and heat transfer medium-steam of a two-phase mixture, a storage means for storing liquid heat transfer medium and a returning device for liquid heat transfer medium, that the memory means comprises fluidically is connected with the trap structure, which provides the memory device liquid heat transfer medium, that at least one connecting line fluidically is connected with the trap structure which, in the at least one connecting line couples heat transfer medium-steam, and in that the recycling means the memory device fluidically with the at least one connecting line, in the memory device temporarily stored liquid heat transfer medium into the at least one connecting line can be coupled.
