Emerging directly irradiated particle receiver technologies have the capability of generating temperatures exceeding 800oC. This is important for industrial processes involving high temperatures, such as electricity generation and thermochemical processes, such as the Bayer alumina process. The utilization of particles in these devices is receiving growing attention due to their potential to withstand high temperatures and their effectiveness on solar radiation absorption. Among all particle receiver technologies being developed globally, the suspension flow receiver, better known as a vortex flow receiver, is receiving growing attention as a method to heat particles in suspension, and hence to heat both phases. In this study, a set of novel scale-up strategies was investigated for a 50-MW windowless directly irradiated vortex-based solar particle receiver to identify the strengths and limitations of each strategy. A receiver design was determined and chosen as the candidate for the current computational study. A systematic analysis was performed to assess the influence of particle mass loading and inlet air mass flowrate on the global performance of the receiver at scale (50-MW) under steady-state conditions with simulated solar flux, along with CARBO-CP used as the particle material. A fixed ratio of overventilation was applied to the induced draft fan to reduce particle egress. The numerical study was conducted using computational fluid dynamics (CFD) software (ANSYS/CFX 2020 R2). The result predicts that up to 60% thermal efficiency can be achieved under high air mass flowrates and particle loadings at scale for the operating conditions analyzed here. [ABSTRACT FROM AUTHOR] |
