🔍 Key Concepts

• Single-element vs multi-element boiler feedwater control systems and what is being measured/controlled • Behavior of proportional, reset (integral), and rate (derivative) control actions in maintaining a stable water level • Typical control strategy needed when only one process variable (e.g., drum level) is used for regulation

💭 Think About

• Ask yourself: with only one measured variable in a single-element system, do you usually need more complex predictive control, or a simpler feedback control? Why? • Think about what happens to drum level with a steady small error over time. Which control actions will eliminate that steady error, and which will not? • Consider how sensitive the system should be to rapid changes. Does a basic single-element system usually include rate (derivative) action, or is that more common in more advanced, multi-element systems?

✅ Before You Answer

• Identify which control actions (proportional, reset, rate) are commonly combined in basic level controllers on marine boilers • Verify which type of action is associated with “on/off” two-position control and whether that matches typical boiler drum level control requirements • Consider stability: which control combination gives reasonably stable control without excessive complexity for a single measured variable system?
