      Boiler control systems are generally broken down into three main functions: burner controls, feedwater controls, and flame safety controls. The three are interrelated as far as actual operation of *the boiler is concerned, but they are basically independent systems. They will, therefore, be discussed separately here. 2.2 Burner Control Systems

      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).

      Distributed control system - Wikipedia

      A distributed control system is a computerised control system for a process or plant usually with many control loops, in which autonomous controllers are distributed throughout the system, but there is no central operator supervisory control. This is in contrast to systems that use centralized controllers; either discrete controllers located at a central control room or within a central computer. The DCS concept increases reliability and reduces installation costs by localising control …

      This means the control system must add feedwater to the boiler at a much greater flow rate in order to maintain the steam drum water level at setpoint. In this situation we would expect to see the control valve much closer to being fully-open as the control system “works harder” to maintain a constant water level in the steam drum.
