Q

The main boiler feed pump discharge is controlled by the admission of steam to the auxiliary turbine. The admission of steam is normally regulated by a __________.

🔍 Key Concepts

• boiler feed pump control methods in steam plants • difference between speed governors and pressure/flow regulating valves • how steam admission to a small auxiliary turbine is usually modulated to match feedwater demand

💭 Think About

• Ask yourself: Is the system trying to keep the pump speed constant or the feedwater flow/pressure matched to boiler demand? • Which device would sense changes in boiler conditions (like drum level or steam flow) and then adjust steam admission to the turbine? • Which of these options directly controls steam to the turbine rather than just limiting maximum speed for overspeed protection?

✅ Before You Answer

• Identify which choices are primarily overspeed protection devices versus control/regulating devices. • Decide whether boiler feed control usually needs constant discharge pressure or variable flow following boiler load. • Make sure the device you pick would realistically be installed in the steam supply line to the auxiliary turbine to throttle or modulate that steam.
