Boiler-Tuning Basics, Part I - powermag.com

In any coal-fired boiler, airflow demand is a function of the boiler firing rate or boiler demand (Figure 3). Gas- and oil-fired boilers have lower O2 requirements at higher loads. 3. Extra air is a good thing. A typical O2 set point curve for a coal-fired plant is a function of boiler firing rate or boiler demand.
