Bio-char combustion in a Fluidized bed Gasifier

Biomass is finding increasing use as a fuel for power generation because of the advantages associated with it, such as low sulfur, low ash contents, and zero net carbon release. Fluidized bed gasifiers impart excellent mixing and gas/solid contact, resulting in high reaction rates and conversion efficiency. This work focuses on the modeling and simulation of the combustion reactor, riser, which is hooked to a biomass gasification reactor. Apart from residual char combustion, the riser serves as a sink for the small amounts of rich tar solvent and tar contaminated water occurring in the plant. The model is able to deal with highly volatile fuels and liquid water. The book presents a model that is robust and can be easily adapted to realize any scenario.
