Effect of baffle structure on the dynamic transportation behavior of s‐liked biomass fuels in a rotating drum

Abstract

Biomass energy is one of the potential renewable energy sources in the world. As the most common biomass materials, plants, wood, and waste are familiar to people and widely used in a broad range of industries. [1][2][3][4][5] Biomass materials like wood and plants are supposed to be converted into suitable forms of energy through direct combustion, which can be grown energy crops, forest residues, food processing, horticulture, or human waste from sewage plants. Meanwhile, fuel and electricity are the most useful energy forms. Therefore, researchers are attempting to develop more efficient ways to use biomass as fuel and produce more biomass materials for energy production. Over the past decades, biomass energy has been considered to be modernized and popular. However, the high moisture content of fresh biomass materials can decrease the energy efficiency of the conversion process and increase the emission of pollutants.

Residence Time Distribution of Non-Spherical Particles in a Continuous Rotary Drum

“…Most of the studies on the RTD measurement in rotary drums are dedicated to spherical particles as reviewed, e.g., by Lu et al [14], while in industrial application, particles are mostly non-spherical [15,16]. Some other researchers study non-spherical shape in rotary drums via the means of experiments and simulation, such as cylindrical particles (such as broken rice or wood pellet) [10,11,17,18], cuboid particles (such as wood chips or alumina) [5,15,17,19], pharmaceutical tablets [1], ellipsoid particles [20], polyhedral particles [21], and cubic particles [16,18]. In addition, even spherical particles may undergo shape change due to cohesion, breakage, or reaction [7,22].…”
