Preliminary Assessment of a Simple Method for Evaluating the Flow Properties of Solid Recovered Fuels

Abstract

The increasing interest in combustion of solid recovered fuels (SRF), whose physical properties may significantly differ from those of conventional solid fuels, draws attention to the handling of these materials. In this article a simple method for evaluating particulate solids flow properties based on a solid extrusion procedure is assessed. The effects of the main geometrical parameters of the tester and of the testing operating condition are investigated. Results are critically discussed by comparing them with the flow properties evaluated in a Schulze ring shear tester.

Keywords:

• powder extrusion
• powder flow properties
• shear testing
• solid recovered fuels
