🔍 Key Concepts

• boiler water level control and dangers of high water level • effects of high water level on steam quality and carryover • difference between securing vs reducing feedwater and using blowdown lines

💭 Think About

• Think about what happens inside the boiler drum when the water level gets too high. How does that affect steam going to the engine or turbine? • Which action would immediately and safely stop the level from rising further, without causing sudden stress or damage to the boiler? • Which options are more appropriate for low water rather than high water conditions?

✅ Before You Answer

• Identify which valve or control directly stops additional water from entering the boiler (feedwater control). • Consider which actions (like blowing down or securing fires) could be too drastic or even unsafe just for a high level condition. • Ask whether the situation calls for completely stopping a system or modulating/reducing it to bring the level back into normal range.
