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.
PID controller consists of three terms, namely proportional, integral and derivative control. The combined operation of these three controllers gives control strategy for process control. PID controller manipulates the process variables like pressure, speed, temperature, flow, etc.
A PID loop is an automatic control system that calculates how far a mea-sured variable is from its setpoint and, usually, controls an output to move the measured variable toward the setpoint. The loop performs pro-portional, integral, and derivative (PID) calculations to determine how aggressively to change the output. The goal of PID control is to reach a setpoint as quickly as possible with-
Another PID works as outer loop controller which controls the physical parameters of the system such as temperature, pressure, flow etc. Hence, cascaded PID controller reduces the time constant of the system and increases the controller working frequency. Cascade control system has some distinguishing features.
