Introduction. Oxyfuel combustion is one of the leading technologies considered for capturing CO 2 from power plants with CCS. This involves the process of burning the fuel with nearly pure oxygen instead of air. In order to control the flame temperature, some part of the flue gas are recycled back into the furnace/boiler.

Fig. 1 illustrates the primary components at WAC in a process flow diagram. The plant design is based on the Shell Coal Gasification Process (SCGP) in which pulverized fuel mix is converted to synthesis gas (syngas) under substoichiometric conditions in a dry feed slagging entrained flow gasifier at elevated temperatures between 1500 and 1800 °C.. The gas is subsequently cooled for cleaning ...
