PRODUCTION OF MEDIUM PRESSURE STEAM BY SOLAR HEATED OIL

Objectif

To demonstrate the feasibility of producing medium pressure steam with solar energy. End-use is in the textile industry.
The measuring campaign lasted from June 1983 to June 1984 and demonstrated the unsuitability of the system for steam production. Indeed 80% of the solar energy was lost through poor control of the reflector angles, thermal losses during oil flow and storage and, dust on mirrors. No steam could be produced.
The plant consists of a series of oil filled tubes positioned at the focus of a parabolic solar panel. The complete plant numbers of 36 such panels. Each panel can partially rotate to follow the sun's movement. The total area of the panels is 100 m2. The oil is heated by the concentration of sunlight reflected on the tubes. The heated oil flows into a steam turbine to produce medium pressure steam, which would have been used to supplement the existing conventional steam producing system.
The movement of the panels is computer controlled to maximize the amant of energy collected. It has been demonstrated that a 2 degree error in alignment causes a 60% loss in collected energy.
