🔍 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.
