System and method for burning vanadium-containing fuels

摘要

In one aspect, a combustion system (10) is configured to facilitate preventing the formation of vanadium pentoxide (V 2 O 5 ) and decrease a concentration of at least one of vanadium trioxide (V 2 O 3 ) and vanadium tetroxide (V 2 O 4 ) particles in an exhaust. The combustion system (10) includes a vanadium-containing fuel (14) and a combustor (12). The combustor (12) is configured to generate a combustor exhaust gas (22) including vanadium trioxide (V 2 O 3 ) and/or vanadium tetroxide (V 2 O 4 ) particles and to combust a reduced-oxygen mixture including the vanadium-containing fuel (14), ambient air (20), and a portion of the combustor exhaust gas (18). The combustion system (10) also includes a particle separator (24) configured to remove substantially all of the V 2 O 3 and/or V 2 O 4 particles from the combustor exhaust gas (22).
