Abstract

The effect of oxygen supply to the gasifier in a circulating fluidized bed system on the cold gas efficiency was estimated. Oxygen supply with low steam supply resulted in an increase in the cold gas efficiency when the excess heat was recovered by the steam generation and steam gasification of char. When the oxygen supply exceeds a certain amount, the cold gas efficiency decreased almost linearly.
