🔍 Key Concepts

• Two-element vs three-element feed water regulators in boiler automation • Which process variables are the “elements” (measured signals) in each type of regulator • Relationship between steam flow, drum level, and feedwater control

💭 Think About

• Identify what the two "elements" are in a typical two-element feed water control system for a boiler drum. • Ask yourself which of the choices would change almost immediately when the boiler load (firing rate/steam demand) changes. • Compare what is usually controlled (drum level) versus what is usually used as a secondary, fast-responding signal to anticipate level change.

✅ Before You Answer

• Remember that drum water level itself is one element; the question is really asking about the other element. • Eliminate any options that are not commonly measured as a primary control signal in automatic boiler feedwater systems. • Verify which variable changes directly with boiler load/steam demand, and is therefore most useful as a feedforward signal in a two-element regulator.
