  • Coal/coke/heavy residual oil boiler with sulfur and carbon dioxide capture and recovery
    Patent number: 8084010
    Abstract: A pulverized coal/coke (PC) boiler combusts carbon-based fuel with substantially pure oxygen and a flue gas recirculation stream (containing predominately carbon dioxide) at varied ratios to achieve a desired boiler temperature profile while producing captured sulfur, a high purity captured CO2 and electric power. The boiler includes at least one of (a) a mechanism for admixing a pulverized solid carbon-based fuel with an alkali metal salt and (b) injecting alkali metal salt into the boiler combustion zone containing a pulverized solid carbon-based fuel.
    Type: Grant
