Higher temperature contributes to higher energy and exergy
efficiencies of the product gas in biomass and coal co-gasification,
indicating that the reaction temperature should be kept at the
highest possible values. However, higher reaction temperature
could lead to other problems, such as higher operational costs and
high temperature agglomeration. Therefore, the appropriate high
temperature should be considered for the co-gasification of coal
and biomass in a fluidized bed gasifier.
