Cyclone furnaces are a significant source of stationary NOx emissions. It was estimated that 0.76 x 10/sup 6/ of NOx (over 6% of stationary source NOx) were emitted from all cyclone-coal-fired utility boilers in 1973. This represents from 19% to 22% of the total NOx emissions from all coal-fired utility boilers in the U.S. Several techniques of combustion modifications were applied in the past to cyclone boilers/furnaces in an attempt to lower their NOx emissions. These include boiler load reduction, low excess air firing, two-stage firing, and switching fuels. This report summarizes available NOx emission data when applying these techniques to cyclone boilers/furnaces. Even though significant reductions in NOx were achieved, none of the techniques was shown to reduce NOx emissions to the level meeting the New Source Performance Standard.
