Question 1 of 27070

Blowing down a water wall header while steaming a boiler at a high firing rate could result in __________.

🔍 Key Concepts

• behavior of water circulation in water-tube boilers at high firing rates • effects of opening a blowdown line connected to a water wall header • how sudden pressure/level changes affect boiler circulation and components

💭 Think About

• When you open a blowdown from a water wall header at high fire, what happens to pressure and water level in that header and nearby tubes? • Which of the options describes a consequence that directly involves the water inside the tubes and headers, not just the external piping? • Think about what good water circulation is needed for at high firing rates, and what happens if you disturb that flow suddenly.

✅ Before You Answer

• Identify which choice is most directly related to internal boiler circulation rather than external piping stress or plant load sharing. • Ask: which effect would be immediate and local to the water wall header itself when you blow it down? • Verify which component (piping, regulator, other boilers, water circulation) is most sensitive to a sudden pressure drop in a water wall header.
