Molten Salt Circulation Pump for Parabolic Trough Concentrated Solar Power

Molten Salts are increasingly used today in CSP plants for heat storage or as primary Heat Transfer Fluid (HTF) due to their high specific heat capacity. When a thermal storage reservoir using molten salts is integrated into a CSP plant, electricity can be generated even after the sun goes down, with an extended operation period of up to 6-8 hours.
Vertical pumps mounted in tanks are preferred nowadays to simplify the molten salt system. This eliminates the pump sumps, isolating valves, level instrumentation and associated heaters. It also reduces heat losses and allow the steam generator system to drain directly into the tanks.
