Steam O2-enriched air gasification of lignite and solid recovered fuel in fluidized bed

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...

Investigation of Fuel Chemistry and Bed Performance in a Fluidized Bed Black Liquor Steam Reformer

Comparison of coal/solid recovered fuel (SRF) with coal/refuse derived fuel (RDF) in a fluidized bed reactor.

An experimental study was undertaken to compare the differences between municipal solid waste (MSW) derived solid recovered fuel (SRF) (complying with CEN standards) and refuse derived fuel (RDF). Both fuels were co-combusted with coal in a 50 kW fluidized bed combustor and the metal emissions were compared. Synthetic SRF was prepared in the laboratory by grinding major constituents of MSW such...

Air gasification of palm empty fruit bunch in a fluidized bed gasifier using various bed materials

0TUse of lignocellulosic biomass as an alternative, renewable and sustainable source of energy has fulfilled part of the growing demand for energy in developed countries. Amongst various technologies applied to convert biomass wastes to biofuel and bioenergy, biomass gasification has attracted considerable attention. In this work, gasification of palm empty fruit bunch as a potential lignocellu...

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...
