Gasification technology biomass gasifiers

The means by which synthetic gaseous fuels could be produced from a variety of biomass sources are variable and many of the known gasification technologies can be appHed to the problem (70,71,76—82). For example, the Lurgi circulatory fluidized-bed gasifier is available for the production of gaseous products from biomass feedstocks as well as from coal (83,84). 

The gasification process can use a variety of biomass resources, such as agricultural residues and wastes, or specifically grown energy crops. The technologies for gasifying... 

These results are important since they highlight that once biomass has been gasified to synthesis gas, the usual processing technologies can be used for chemical synthesis, which are well understood by the industry. As the efficiency of the gasification step is fairly competitive with coal, this may make the gasification of biomass a fairly viable option, but the other metrics developed in this book must be applied as well. 

Examination of state-of-the-art thermal biomass gasification technology shows that moving-bed gasifiers have been studied and extensively tested... 

Recently two feedstock databases have been established where a significant amount of information is provided for a variety of biomass feedstocks (27, 28). In the databases, the basic physico-chemical properties of biomass fuels can be found which will provide basic information to gasifier developers as well as gasifier users on the quality and suitability of the various fuels for the gasification technologies they either develop or use. 

A power plant can generate electric power using biomass from the trees. A gasifier is capable of converting tons of wood chips per day into a gaseous fuel that is fed iuto a fuel cell. The composition of gas depend on biomass gasification technology.
