METHOD OF DRAINING HEAT-TRANSFER OIL IN A SOLAR POWER PLANT, AND EQUIPMENT FOR DRAINING, STORING AND REPLENISHING HEAT-TRANSFER OIL IN ORDER TO IMPLEMENT SAID METHOD.

摘要

The invention relates to a method of draining heat-transfer oil in a solar power plant, and to equipment for draining, storing and repositioning heat-transfer oil in order to implement said method. The method includes filling auxiliary ducts, flushing the oil from the solar power plant loop, cooling the outgoing oil and extracting the oil by suction; replenishing includes filling the loop by impulsion and emptying the auxiliary ducts by aspiration. The installation includes an oil tank (7); a pumping assembly (6); an oil cooler (5); communication ducts between same; a depressor or aspiration assembly (8); an assembly of ducts for emptying (3) the loop of the installation, forming a closed loop; and an assembly of filling ducts (4), forming a closed loop.
