What is the primary indication of fouling of a heat exchanger?

🔍 Key Concepts

• Heat transfer efficiency in a fouled vs. clean heat exchanger • Relationship between flow resistance (pressure drop) and deposits on tube or shell surfaces • How fouling affects the temperature approach (temperature difference between hot and cold fluids)

💭 Think About

• If deposits build up inside the passages, what happens to how easily the fluid can flow through (think in terms of pressure drop)? • When the heat-transfer surfaces are insulated by scale or slime, does heat transfer become easier or harder, and how would that show up in the temperature difference between the two fluids? • Consider which side’s symptoms (pressure and temperature changes) would be most obvious to an engineer monitoring gauges in the control room.

✅ Before You Answer

• Make sure you connect more restriction in a passage with the correct change in pressure drop across that side. • Decide whether reduced heat-transfer capability would make the outlet temperatures of the two fluids move closer together or farther apart. • Before choosing, double‑check that your option shows both the correct sign of pressure change and the correct direction of temperature‑difference change.

What is the primary indication of fouling of a heat exchanger?

A decreased pressure drop associated with the side where the fouling exists and a decreased temperature differential between the two fluids exchanging heat.

A decreased pressure drop associated with the side where the fouling exists and an increased temperature differential between the two fluids exchanging heat.

An increased pressure drop associated with the side where the fouling exists and a decreased temperature differential between the two fluids exchanging heat.

An increased pressure drop associated with the side where the fouling exists and an increased temperature differential between the two fluids exchanging heat.
