ADVANCED REBURNING FOR REDUCTION OF NOX EMISSIONS IN COMBUSTION SYSTEMS |
摘要 |
Techniques for enhancing the burnout zone chemistry for NOx reduction are disclosed. The key parameters for the enhancement of burnout zone chemistry are: (a) a reaction temperature in the range from about 1300 DEG F. to about 1900 DEG F., and optimally in the range from 1400 DEG -1700 DEG F.; (b) a carbon monoxide concentration below about 0.5 percent; and (c) the presence of nitrogenous reducing species. By controlling the stoichiometry associated with reburning to produce a slightly fuel-rich region for selective reducing agent injection, reductions can be achieved at relatively low temperatures which approach those obtained by conventional catalytic reduction. |
