摘要

Operating a solar thermal power plant with a heat transfer medium circuit, comprises: heating directly by solar radiation, a liquid, a salt and a melt comprehensive heat carrier (3); and subsequently, against in the steam circuit of a steam turbine, cooling the circulating working medium (20), where mixture of substances comprising molten salt and water at least prior to heating by solar radiation, is used as heat transfer medium. An independent claim is also included for a solar thermal power plant with a heat transfer circuit in which a liquid, a salt, a melt comprehensive heat carrier rotate, thus are directly heated by solar radiation, and the circulating working medium is cooled against in the steam circuit of a steam turbine, where the heat transfer circuit has at least two receivers for heating the heat transfer medium, which are arranged so that the heat carrier can flow through serial.
