The Sevilla Powder Tester: A Tool for Measuring the Flow Properties of Cohesive Powders at High Temperatures

Understanding the flowability of cohesive powders at high temperature is great importance for many industrial applications where these materials are handled harsh thermal conditions. For instance, Calcium-Looping (CaL) process, involving transport, storage and fluidization limestone temperature, being considered nowadays as a promising technology thermochemical energy (TCES) in concentrated solar power plants (CSP). In this context, High Temperature Seville Powder Tester (HTSPT) presented work useful tool to analyze how flow behavior changes with temperature. The manuscript reviews main results obtained so far using novel apparatus. change powder cohesiveness therefore depending on particle size, material properties nanosilica surface coating illustrated.
