SYSTEM AND METHOD FOR BURNING VANADIUM-CONTAINING FUELS

摘要

In one aspect, a combustion system is configured to facilitate preventing the formation of vanadium pentoxide (V2O5) and decrease a concentration of at least one of vanadium trioxide (V2O3) and vanadium tetroxide (V2O4) particles in an exhaust. The combustion system includes a vanadium-containing fuel supply and a combustor. The combustor is configured to generate a combustor exhaust gas including vanadium trioxide (V2O3) and/or vanadium tetroxide (V2O4) particles and to combust a reduced-oxygen mixture including the vanadium-containing fuel, ambient air, and a portion of the combustor exhaust gas. The combustion system also includes a particle separator configured to remove substantially all of the V2O3 and/or V2O4 particles from the combustor exhaust gas. A method for combusting fuel and a power generation system are also provided.

1. A combustion system comprising:
a vanadium-containing fuel supply; at least one combustor configured to:
generate a combustor exhaust gas including at least one of vanadium trioxide (V2O3) particles and vanadium tetroxide (V2O4) particles; andcombust a reduced-oxygen mixture comprising the vanadium-containing fuel, ambient air, and at least a portion of the combustor exhaust gas, thereby facilitating the prevention of vanadium pentoxide (V2O5) particle formation; and a particle separator configured to receive the combustor exhaust gas and remove substantially all of the V2O3 particles and the V2O4 particles from the combustor exhaust gas.
