Abstract
The effectiveness of combustion
modifications, including staged combustion and
reburning, for the control of nitrogen oxide
emissions from coal fired combustors is most often
limited by problems due to carbon burnout or flame
impingement. This paper presents new data on the
use of selective reducing agents, such as ammonium
sulfate, suggesting that a hybrid control scheme
is possible which uses combustion modification to
provide those conditions which optimize the
selective reduction process. Very low emission
levels appear possible that can presently only be
achieved by catalytic reduction.
