DOI: 10.1002/er.4396
Abstract: Using a phase Doppler‐anemometer measurement system, the cold gas/particle‐airflow behavior in a 1:40 scale‐model furnace was assessed to study the influences of adjusting the inner–secondary‐air ratio in a 600‐MWe multi‐injection and multistaging down‐fired boiler. Numerical… read more here.
