🔍 Key Concepts

• Steam system pressure equalization between boilers on a common header • What happens inside a boiler when steam demand or flow suddenly changes • The meaning of priming, carryover, thermal shock, and how each occurs

💭 Think About

• When a higher‑pressure boiler is suddenly connected to a lower‑pressure line, which way will steam flow and how fast? • What effect would that sudden flow have on the water level and water surface inside the boiler? • Which of the listed problems is most directly caused by a sudden, violent change in steam flow across the water surface, rather than by temperature change or low feedwater level?

✅ Before You Answer

• Make sure you understand how priming and carryover occur (what inside the boiler causes them). • Review what thermal shock actually requires (big metal temperature difference, hot-to-cold or cold-to-hot). • Confirm whether low water or an overloaded superheater would logically be the first, most direct effect of suddenly connecting a much higher-pressure boiler to the line.
