Boiler Drum Level Control by Using Wide Open Control with Three Element Control System

This arrangement is called "Three Element Drum Level Control" (3E) because the algorithm uses level, BFW flow, and steam flow. "Single Element" or (1E) control should be used when either flow is too low or has bad quality . 1E is a simple PID loop with the level as process variable (PV), the output going to the valve, and no feed forward.
