✦ Synopsis
Results are presented on the effect of scale on NO, emissions from swirl stabilized pulverized coal flames. Three burner scales were investigated in the range 0.9 to 3.4 MW in an experimental furnace. Each burner was geometrically similar and constant velocity was used as the primary aerodynamic scaling criterion. Each flame was extensively probed for gas composition and temperature. Furnace exhaust NO, emissions are seen to marginally increase with increased burner scale. This observation is explained in terms of the effect of scale on the mixing rate between fuel and air and the consequential effect on the in-flame chemistry.
