Question 1 of 27070

For proper operation, auxiliary boiler feed water must have which of the following characteristics?

🔍 Key Concepts

• Boiler feed water treatment and why impurities are controlled • Effect of oxygen, pH, and alkalinity on corrosion and scale formation • Difference between low pH (acidic) and alkaline (basic) conditions in metals protection

💭 Think About

• Think about which water condition helps prevent corrosion and scale inside the boiler rather than causing it. • Ask yourself: does high oxygen protect steel surfaces, or does it promote rust and pitting? • Consider whether boiler water should be more acidic or slightly alkaline to protect metal surfaces and keep sludge in suspension.

✅ Before You Answer

• For each option, decide if it would increase or decrease corrosion in steel boiler parts. • Recall that oxygen scavengers are often used in boilers – why would that be necessary if a high oxygen concentration were desirable? • Review the typical pH range specified for boiler feed water and whether that corresponds to low pH (acidic) or controlled alkalinity (slightly basic).
