CPFD simulations of an industrial-sized dual fluidized bed steam gasification system of biomass with 8 MW fuel input
TL;DR: In this paper, an industrial-sized dual fluidized bed (DFB) system was simulated with the commercial code CPFD Barracuda and four drag models were tested, and it was found that the EMMS drag model fits best with an error of below 20%, whereas the other drag models produced much larger errors.
Journal ArticleDOI
An overview of processes and considerations in the modelling of fixed-bed biomass combustion
TL;DR: In this paper, the authors provide a fundamental overview of the methodologies employed in the modelling of laboratory-scale fixed-bed combustors and treatment of the fundamental thermo-physical fuel characteristics which need to be considered when undertaking macro-scale (bed-level) modelling.
Journal ArticleDOI
Modeling kinetics-transport interactions during biomass torrefaction: The effects of temperature, particle size, and moisture content
TL;DR: In this article, a comprehensive one-dimensional model accounting for the effects of heat and mass transfer, chemical kinetics, and drying was developed to describe the torrefaction of a single woody biomass particle.
Journal ArticleDOI
Effects of various operational parameters on biomass gasification process; a modified equilibrium model
TL;DR: In this paper, a modified equilibrium model based on Gibbs free energy minimization was used to study the performance of the biomass gasification process and the effects of parameters such as equivalence ratio, gasification temperature, fuel type and its moisture content.
Journal ArticleDOI
Single particle flame-combustion studies on solid biomass fuels
TL;DR: In this paper, single particles were supported in a water-cooled cover and then exposed above a flame, simulating biomass combustion in a furnace, using high speed image capture.

Coal Combustion and Gasification
L. Douglas Smoot,Philip J. Smith +1 more
TL;DR: In this paper, the authors discuss coal processes and properties, basic reaction processes of coal particles, including coal devolatilization, char oxidation, and volatiles combustion, and fundamental equations and background for turbulent combustion systems.

Properties of wood for combustion analysis.
TL;DR: A systematic compilation of 21 different property values of wood and bark fuel was made to facilitate the engineering analysis and modeling of combustion systems as discussed by the authors, where the properties such as density, porosity, and internal surface area are related to wood species whereas bulk density, particle size, and shape distribution are related with fuel preparation methods.

Thermal behaviour and kinetics of coal/biomass blends during co-combustion
TL;DR: The thermal characteristics and kinetics of coal, biomass and their blends were evaluated under combustion conditions using a non-isothermal thermogravimetric method (TGA) and showed that the chemical first order reaction is the most effective mechanism for the first step of biomass oxidation and for coal combustion.
