🔍 Key Concepts

• Thermo-hydraulic feedwater regulator basic design (inner and outer tubes, closed system) • Difference between maintaining constant level vs. controlling level within a range • What happens to the system on failure of the actuating/pressure system in safety design

💭 Think About

• Think about whether boiler water level can realistically remain perfectly constant at all load ranges, or if it normally fluctuates within limits. • Consider how a thermo-hydraulic regulator senses drum level: which tube is in contact with drum steam/water and which one forms a sealed loop? • On loss of actuating pressure in a safety‑conscious design, would you expect the feed valve to fail fully open, fully shut, or to some intermediate/safe position?

✅ Before You Answer

• Verify how the inner and outer tubes of a thermo-hydraulic generator are connected: which is part of a closed system and which is open to the drum. • Check whether the regulator’s function is to keep level absolutely constant or to maintain it within a controlled band around the normal level. • Confirm what standard boiler practice is for fail-safe position of a feedwater control valve when the sensing/actuating system fails.

Question 1 of 20

Which of the following statements is true concerning the operation of a boiler thermo-hydraulic feed water regulator?

A failure in the regulator pressure actuating system opens the feed valve wide.

The regulator maintains constant water level throughout all boiler load ranges.

The inner tube of the generator is open to the steam and water in the steam drum.

The outer tube of the generator transfers heat to the inner tube of the closed system.
