7th of April 2015
• Reliable operation
• No negative interference with conventional steam supply
• Solar steam supply often higher than demand
• SD function as Ruth storage works well by supplying steam in a pressure
range from 7 barg to 14 barg
• High concentration of minerals in steam drum
=> need for blow down more often
• High pH values can damage components
=> choose accordingly

• SolSteam project: test of alternative separator
• Motivation: save investment costs

Manual control of condensate level during cyclone operation
Operation along steam drum:
• Works well
• Stabilizes operation
Solar steam supply constant even at strong variations in demand
Operation along cyclone:
• Manual control works
• Automatic control will be implemented
• Fast control needed
