How Do Burner Combustion Control Systems Work? - CrossCo

Each boiler has a boiler master, which is an A/M/Bias station that handles the firing rate for that boiler. In AUTO, the boiler master receives the plant master output, biases it, and sends that % to the fuel and air flow controllers. In MANUAL, the boiler master output is adjusted by the operator.

Boiler CCS PID loops must be put in auto in order. The drum level is independent, as are auxiliary loops such as continuous blowdown. Air flow must be in cascade before fuel flow, and fuel flow should be forced to manual if air flow is not in cascade. Air flow and fuel flow must both be in cascade to put the boiler master in auto.
