How Do Burner Combustion Control Systems Work? - CrossCo

A boiler CCS's PID (proportional – integral – derivative) loops and A/M/Bias (auto / manual / bias) stations should generally be configured to track as much as possible.SPs (set-points) should track PVs (process variables) when not in auto.Cascade master outputs should track slave SPs if the slave is not in cascade (auto output and remote SP).
