Advanced Distributed Cocurrent Gasifier
The advanced distributed cocurrent gasifier (ADCG) was developed to gasify biomass and coal for use in downstream
applications such as a microturbine or combustor. Carbonaceous feedstock is fed through the bottom and air injected
approximately a third of the way up the gasifier. Depending on the physical characteristics of the feedstock, the
gasifier acts as a cocurrent fixed-bed gasifier or a slurry gasifier. Two downstream cyclones are used to filter
particulates out of the gas stream. Char and ash are removed by an auger at the top of the gasifier.
