Rig Uses
Specification
Fuels•Coal
This rig can be operated either as a circulating fluidised bed combustor (CFBC) or a circulating fluidised bed gasifier (CFBG):•CFBC enables studies of both air- & oxy-fired combustion of various fuels. •CFBG produces syngas (synthesis gas) from various fuels which can be cleaned and used in gas engines.Different gas cleaning methods exist for CFBG:•Using a hot gas filtration unit (HGFU), particles can be removed at high temperatures•Using a heat exchanger allows low temperature particle removal.
