Q

A coil-type automatically fired auxiliary boiler is to be laid up wet for an indefinite period. The boiler water should be treated to ensure that __________.

🔍 Key Concepts

• Wet lay-up procedures for auxiliary (coil-type) boilers • Purpose of water treatment during extended idle periods • Effects of pH control vs. oxygen scavengers vs. sludge formation

💭 Think About

• Ask yourself: During a long wet lay-up, what is the MAIN risk to the internal metal surfaces of the boiler? • Which water-condition factor, if kept within a proper range, best prevents corrosion over time? • Which choice sounds like an on-line operating concern (normal running) rather than a long-term preservation concern?

✅ Before You Answer

• Identify which option directly addresses corrosion protection of waterside surfaces during storage • Distinguish between controls used for normal operation (like blowdown and sludge control) and those for preservation/lay-up • Check which option could be clearly specified by a manufacturer’s recommendation and monitored over time
