摘要：Biomass gasification modeling is a powerful tool
used to optimize the design of a gasifier. A detailed kinetic model
was built by the current authors [1] to predict the behavior of
air blown downdraft gasifier for a wide range of materials
within the range of (38≤C≤52) %, (5.2≤H≤7) %, and
(21.7≤O≤45) %. The model was verified and showed a good
stability for a wide range of working parameters like
equivalence ratio and moisture content. In the current research,
4 main tar species are added to the model to represent tar
formation using detailed kinetic reactions. The yield of tar
species is discussed for different zones of a gasifier based on
temperature of each zone. Mass and energy balance are
calculated. 18 different kinetic reactions are implemented in the
kinetic code to predict the optimum working conditions that
leads to the production of higher value producer gas. Results
conclude that using ER of 0.3 with moisture content levels lower
than 10% will lead to the production of higher yields of syngas
with lower amounts of tar.
