Abstract:
1. A steam-generating combustion system, comprising: an oxidant delivery system providing an oxidant stream; an oxygen enriched gas generation system providing an oxygen enriched gas with 21% to 100% oxygen to the oxidant delivery system; a fuel delivery system providing a fuel stream with a fuel mass flow rate; a combustion chamber arranged to receive and combust the fuel stream in the oxidant stream and generate steam, the combustion chamber generating flue gas having a flue gas mass flow rate which is smaller than the mass flow rate of flue gas generated by the combustion chamber when operated with the same fuel mass flow rate and with air as the oxidant stream; and a flue gas pollutant control system receiving the flue gas from the combustion chamber and reducing the amount of at least one of particulate matter, SO
