Q

The purpose of the air chamber at the discharge side of a steam reciprocating boiler feed pump is to __________.

🔍 Key Concepts

• Function of an air chamber in positive displacement pumps • How reciprocating motion affects flow in a discharge line • What systems are normally used to add chemicals (like boiler compound) to a boiler

💭 Think About

• Think about what the flow from a reciprocating pump would look like without any special fittings. Would it be smooth or intermittent? • What does a trapped volume of air in a chamber do when pressure increases and decreases in a pipe? • Which of the choices describes something usually done by a separate system (not on the discharge side of a feed pump)?

✅ Before You Answer

• Identify how a reciprocating pump delivers water during each stroke and what that does to pressure in the discharge line. • Consider the compressibility of air versus water and how that might affect pressure surges. • Verify which function (draining cylinder, speed adjustment, chemical addition, flow smoothing) is typically associated with a discharge-side air chamber.
