Abstract

Quantification of abrasion, erosion and corrosion is important to determine operation costs for solar particle receivers, including particle replacement, maintenance, and especially the need for replacement of components during lifetime of the solar particle plant. This paper deals with the assessment of the quantities of abrasion and erosion of particles during operation and the resulting costs for particle replacement. Firstly, the assessment of expected loads on the particles during abrasion are discussed as well as the transfer of these parameters to experimental setups. Secondly, the conducted experiments and the results are described. Finally, the experimental results are transferred to the application by scaling and conversion into cost data. The results indicate particle replacement costs of less than 0.32 €/MWhth (0.36 $/MWhth1). First corrosion experiments indicate, as expected, a siginficant effect of combined high temperature corrosion of metallic structural material in combination of abrasion due to relative movement of particles to structural material.
