By using phase-Doppler anemometry (PDA) measurements within a cold small-scale model for a down-fired 600-MWe supercritical utility boiler, gas/particle flow characteristics were acquired at various staged-air declination angle settings (i.e., 0°, 15°, 30°, and 45°) so as to assess the...

To investigate the aerodynamic field, cold airflow experiments were conducted under different boiler loads in a cold small-scale model of a down-fired pulverized-coal 300 MWe utility boiler. At 300 MWe and 250 MWe loads, a deflected flow field appeared in the lower furnace. In contrast, at a...

To acquire the gas/particle flow characteristics of an in-assembly down-fired 600-MWe supercritical utility boiler, experiments were conducted by using particle dynamics anemometer (PDA) measurement within a two-phase small-scale model at various staged-air ratio settings (i.e., 0%, 6%, and...
