  • Flue gas recirculation system
    Patent number: 6247917
    Abstract: The present invention relates to an apparatus and method for improving the economics of flue gas recirculation. In particular, the present invention relates to an apparatus for the minimization of oxides of nitrogen (“NOx”) in the exhaust gas of various combustion processes via balanced pressure drops of the recirculation gas, and a method for the calculation of flue gas recirculation percentage. The flue gas recirculation system achieves the balanced pressure drops by sizing the air intake line and recirculation line associated with the system.
    Type: Grant
    Filed: March 16, 2000
    Date of Patent: June 19, 2001
    Assignee: Texaco Inc.
    Inventors: Eric L. Berger, Karl W. Kolthoff, Thomas J. Rankin
  • Flue gas recirculation system and method
    Patent number: 6095792
    Abstract: The present invention relates to an apparatus and method for improving the economics of flue gas recirculation. In particular, the present invention relates to an apparatus for the minimization of oxides of nitrogen ("NO.sub.x ") in the exhaust gas of various combustion processes via balanced pressure drops of the recirculation gas, and a method for the calculation of flue gas recirculation percentage. The flue gas recirculation system achieves the balanced pressure drops by sizing the air intake line and recirculation line associated with the system.
