Biomass Oxy-Gasification Integrated into a Coal Oxy- Boiler

A. Gómez-Barea, B. Leckner & P. Ollero
A biomass gasifier coupled to an oxy­combustion boiler is an attractive concept, enabling simultaneous production of syngas of medium heating value and carbon “capture” from concentrated CO2 taken from the flue­gas of an oxyboiler. Pure oxygen is available for the gasifier, because it is produced for the oxyboiler, taking advantage of the economy of scale of the coal plant. A model of the gasifier is used to study the effect of process conditions on the...
