Torrefaction of Biomass Pellets: Modeling of the Process in a Fixed Bed Reactor
Torrefaction of biomass pellets is considered as a useful pretreatment technology in order to convert them into a high quality solid biofuel that is more suitable for pyrolysis, gasification, combustion, and co-firing applications. In the course of torrefaction, the temperature varies across the pellet, and therefore chemical reactions proceed unevenly within the pellet. However, the uniformity...
متن کاملAerodynamics of a Fluidized Bed of Forestry Biomass Particles with Mechanical Agitation
The aerodynamic behavior of wet forestry biomass particles mechanically shaken in a fluidized bed was analyzed with turning velocity between 0.5 and 2 r.p.s. It was concluded that the agitation exerts an important effect on the fluidization of wet biomass particles. The effect of the agitator is not relevant if the particles have low humidity content. In addition, a methodology based on the Erg...
متن کاملThe Influence of Particle Size, Fluidization Velocity, and Fuel Type on Ash-Induced Agglomeration in Biomass Combustion
*Correspondence: Bernhard Gatternig, Friedrich-Alexander University Erlangen-Nürnberg (FAU), Fuerther Str. 244f, Nuremberg 90429, Germany e-mail: bernhard.gatternig@cbi. uni-erlangen.de Agglomeration of the bed material is one of the main obstacles for biomass utilization in fluidized bed combustors. Especially, high-potential fuels such as fast growing energy crops or biogeneous residues are a...
متن کاملTorrefaction Kinetics of Norwegian Biomass Fuels
Torrefaction kinetics of Norwegian biomass fuels, including spruce (softwood) and birch (hardwood) was studied using a thermogravimetric analyser. Small samples of approximately 10 mg and particle size of 63−125 μm were heated at a constant heating rate of 5 °C/min and kept afterwards for 4 hours in isothermal conditions at different temperatures (230, 240, 250, 260, 270 and 280 °C). A two-step...
متن کاملAcoustic Field Effects on Minimum Fluidization Velocity in a 3d Fluidized Bed
Fluidized beds are used in a variety of process industries because they provide uniform temperature distributions, low pressure drops, and high heat/mass rates. Minimum fluidization velocity is an important factor in understanding the hydrodynamic behavior of fluidized beds, and this characteristic may be modified through high frequency (sound) vibrations. The effects caused by sound wave frequ...
