Combustion characteristics of coal in a pilot scale oxy-circulating fluidized bed combustion system

摘要

1. The shift operating (within 30 min) to oxy-firing from air-firing was smoothly performed with a 0.1 MWth CFBC system.rn2. To prevent air ingress for high purity CO_2 production, preliminary tests were operated under slightly positive pressure (about 50 mmH_2O) at furnace top by ID fan control logic.
