Experimental investigation and optimisation of flow dynamics of gravity moving bed electric heater for olivine particles in CSP

Gravity-driven shell-tube heat exchangers stand out among other solid-particle HX designs due to their low cost, reduced parasitic losses, and ease of integration into various processes. For CSP applications, these heat exchangers are typically used for transferring the heat from the particle loop to the conversion cycle. However,another potential application of a heat exchanger could be for providing additional heat to the particle loop, thus increasing particle loop temperature even further. A potential method for achieving higher particle loop temperatures involves incorporating a superheater after the solar receiver, a concept explored in the MW-scaleCSP prototype within Powder2Powder project.
