Abstract

The indirect steam
gasification in circulating fluidized bed reactors was studied by modelling.
The object of study was a coupled 12 MWth gasifier-combustor system,
which was fired by woody biomass. The heat for the steam-blown gasifier was
produced in the air-blown combustor and transported by circulating solids
between the interconnected reactors. The system was modelled by a semi-empirical
three-dimensional model, which simulated the fluid dynamics, reactions, and
heat transfer in the coupled process. The studied cases included different
temperature levels, which were controlled by the amount of additional fuel feed
to the combustor. The model concept can be later applied to study sorption
enhanced gasification, which is a promising method for sustainable production
of transport fuels to substitute fossil based fuels.
