Development of Cost Effective Oxy-Combustion Technology for Retrofitting Coal-Fired Boilers
Babcock & Wilcox Company
Project Number: FC26-06NT42747
Schematic for typical oxy-combustion process.
To further develop the oxy-combustion technology for commercial
retrofit in existing wall-fired and cyclone boilers by 2012, Babcock
& Wilcox Company will conduct this two-phase research project that
includes pilot-scale testing and a full-scale engineering and economic
analysis. The test facility will be modified to a wall-fired
configuration and a cyclone configuration to determine the performance
of the oxy-combustion process for the respective boiler configurations.
Phase I will evaluate the effect of coal rank used in existing
oxy-combustion boilers; determine equipment requirements for the boiler
island; investigate the potential for multi-pollutant reduction; and
validate an existing 3-D computational flow, heat transfer, and
combustion model for scale-up to a commercial size boiler.
Phase II will conduct an engineering and economic assessment of the
technology for commercial-scale retrofit application; assess carbon
dioxide (CO2) control cost reductions via the integration of air separation unit (ASU), flue gas purification, CO2 compression train, CO2
transportation, and sequestration; evaluate the impact of
oxy-combustion implementation on net power production and cost of
electricity; and determine the boiler population with close proximity
between stationary CO2 sources and their respective geologic sinks.
