Jan 13 2015 · The CCS is then free to modulate the air and fuel as desired. Auto requirements. Boiler CCS PID loops must be put in auto in order. The drum level is independent as are auxiliary loops such as continuous blowdown. Airflow must be in cascade before fuel flow and fuel flow should be forced to manual if airflow is not in cascade.

Cascade Feed Forward and Boiler Level Control Control Guru

Most boilers on a given header must be allowed to be driven by the Plant Master to maintain pressure control. Boilers that have the Boiler Master set in automatic mode (passing the steam demand from the Plant Master to the boiler firing control system) are said to be swing boilers as opposed to base-loaded boilers.
