Abstract

The invention relates to a pipeline system for a linearly concentrating solar power plant (1) with at least one receiver line (13), in which a heat transfer medium is heated by radiating solar energy, or with a central receiver and at least one emptying tank (21) and/or one store for the heat transfer medium, the heat transfer medium having a vapor pressure of less than 0.5 bar at the maximum operating temperature. Furthermore, a gas displacement system (31) is comprised, which connects gas spaces in the at least one emptying tank (21) and/or in the store for the heat transfer medium to one another and which has a central gas store (35) and/or a central gas connection (37) and a central exhaust gas outlet (39), through which gas can be discharged into the surroundings.
