Novel design of central dual-receiver for solar power tower [PDF]
Applied Thermal Engineering, 2015 A novel dual-receiver with a surrounding solar field was proposed to improve the efficiency of a solar power tower (SPT). The new design combined an external and a cavity receiver, corresponding to the boiling and superheating sections respectively, and provided a simple yet controllable heat flux distribution on both sections.

Optical and radiation considerations in bladed receiver designs for central tower systems [PDF]
AIP Conference Proceedings, 2019 The bladed receiver is a promising concept for improving performance of traditional external receivers in commercial-scale central tower systems due to its light-trapping benefits for reducing reflections and thermal emission. This study reviews the optical and thermal radiation considerations in its design.

Reliability Analysis of Solar-Gas Hybrid Receivers for Central Tower Plants
Energy Procedia, 2015 A novel Solar-Gas Hybrid Receiver (SGHR) that combines the function of a solar receiver and a gas boiler in a single device is presented. This concept requires less equipment and maintenance compared to the Solar Gas Hybrid (SGH) concept, in which the boiler and the solar receiver (SR) are independent devices.
