Thermal energy recovery via integrated small scale boiler and superheater

The boiler operating without superheater captured 66% of incoming thermal energy. Operating in combination with the superheater showed a 10% increase in thermal absorption capability at working fluid flow rate of 3 mg/s. Working fluid was superheated successfully from saturation temperature of 76 °C-85 °C. Increased head loss associated with the superheater and boiler combination limited flow rates. The system achieves measurable superheat of working fluid when applied to the real-world challenge of thermal energy scavenging.
