INDIRECTLY HEATED FLUIDIZED BED BIOMASS GASIFICATION

higher energy content than typically produced during biomass gasification. Higher energy densities in the product gas are achieved by indirectly heating the gasifier using a latent heat ballast. Gas produced in an air-blown biomass gasifiers typically have heating values only 10 to 20% that of natural gas.

limited to small numbers of reactions and species with clearly defined mechanisms. In this work, a non-stoichiometric equilibrium model using air as gasification agent was proposed to predict the performance of a biomass gasifier. The optimal operation parameters and the factors affecting LHV of product gas were investigated. In addition, the effect of fuel type change (H/C and O/C) on

A Comprehensive Review of Biomass Gasification Process

during biomass gasification. 2. Fluidized Bed Gasifier . In the gasification process, the biomass is heated to a higher temperature producing chemical and physical changes resulting from volatile products and solid carbonaceous residues. The amount of volatile products depends on the heating rate, the temperature height and the type of biomass.

Thermal Gasification of Biomass - IEA BioEnergy Agreement

Gasification is a complete thermal breakdown of the biomass particles into a combustible gas, volatiles and ash in an enclosed reactor (gasifier) in the presence of any externally supplied oxidizing agent (air, O 2, H 2 O, CO 2, etc.) when equivalent ratio (ER) is < 1.ER = 1 if the stoichiometric amount of oxidising agent is present.

What is biomass gasification power generation?

In brief, biomass gasification technology uses biomass as raw materials, oxygen, steam or hydrogen as agent, and turn the biomass into combustible gas through chemical reaction at high temperature. The combustible gas can be used in industrial and agriculture production, such as power generation, supplying heat, methanol and ethanol synthesis.

(PDF) Gasification of a Solid Dry Waste (Biomass

Gasification is a thermo-chemical system by which a solid dry waste (biomass) can be converted into a synthetic (syn) or producer gas. Syn gas of gasification is different than a hot flue gas generated from conventional combustion process which bears no residual heating value (Higman and Burgt, 2003).
