Rheological study of powder flow is a hot topic in recent years. This paper aims to provide a novel alternative method for powder rheological characterization, instead of the conventional melt rheology. To achieve this goal, powders including glass beads, pulverized coal and alumina with different particle sizes were used as experimental materials.

Torrefaction removes moisture and volatiles from biomass, leaving biocoal. Torrefaction of biomass,, wood or grain, is a mild form of pyrolysis at temperatures typically between 200 and 320 °C. Torrefaction changes biomass properties to provide a better fuel quality for combustion and gasification applications. Torrefaction produces a relatively dry product, which reduces or eliminates ...
