🔍 Key Concepts

• Coil-type forced circulation auxiliary water-tube boiler basic arrangement (flash chamber, coils, accumulator, superheater) • Difference between where water vs steam is located in the system • Purpose of an accumulator and of a superheater in steam systems

💭 Think About

• Think about where the actual steam generation happens in a coil-type boiler: Is it in a drum, coils, or another component? • Consider what an accumulator is designed to do in a steam system: store what, in what phase, and under what conditions? • Review what a radiant superheater does: does it dry steam, raise its temperature, or separate moisture mechanically?

✅ Before You Answer

• Be clear on which component acts like a steam separator/flash chamber versus a storage/accumulator • Ask yourself: in normal operation, would an accumulator be expected to contain mostly water or mostly steam, and why? • Verify whether moisture removal from steam is normally associated with a superheater or with separators/driers located before or after it.
