Optimization of a Bubbling Fluidized Bed Plant for Low-Temperature Gasification of Biomass

Investigation of the Effects of Introducing Hydrodynamic Parameters into a Kinetic Biomass Gasification Model for a Bubbling Fluidized Bed

GASIFICATION vs COMBUSTION OF WASTE/BIOMASS IN FLUIDIZED BED REACTORS

This paper presents a comparison of commercial fluidized bed gasifiers and combustors used to recover energy from municipal solid wastes and biomass. The work reported here is excerpted from four case studies prepared for the International Energy Agency’s Bioenergy Agreement, under Task 23 (Energy from Thermal Conversion of MSW and RDF, 1998-2000) and Task 36 (Energy from Integrated Solid Waste...

Simulation of Biomass Gasification in Fluidized Bed Using Aspen Plus

Gasification is a thermo-chemical process to convert carbon-based compounds such as biomass and coal into a gaseous fuel. Among the various types of gasification methods, fluidized bed gasification is one which is considered as more efficient method than others as biomass is fluidized in a mixture of air/oxygen and steam. In the present study, a comprehensive steady state process model has been...

Biomass Gasification in Fluidized Bed Gasifiers Modeling and Simulation

Using woody biomass as a resource for production of biofuel, heat and power through gasification has been studied for years. In order to reduce the cost of operating and to design the full-scale gasification plant developing a general model to be applicable for different ranges of input data with acceptable level of accuracy, is needed. In order to develop such model for the gasifier, as the ma...

Steam-air fluidized bed gasification of distillers grains: Effects of steam to biomass ratio, equivalence ratio and gasification temperature.

In this study, thermochemical biomass gasification was performed on a bench-scale fluidized-bed gasifier with steam and air as fluidizing and oxidizing agents. Distillers grains, a non-fermentable byproduct of ethanol production, were used as the biomass feedstock for the gasification. The goal was to investigate the effects of furnace temperature, steam to biomass ratio and equivalence ratio o...
