Question 90Steam Plants - QMED70% to pass
To prevent pulsations from developing in the boiler feed water lines, the discharge side of a reciprocating feed pump is equipped with a/an _______________.
AI Explanation
The correct answer is B) air chamber.
An air chamber is installed on the discharge side of a reciprocating feed pump to prevent pulsations in the boiler feed water lines. The air chamber acts as a cushion, absorbing the pressure fluctuations created by the intermittent discharge of the reciprocating pump. This helps to maintain a steady, continuous flow of feed water to the boiler, preventing damaging pressure pulsations.
The other options are incorrect because:
A) A feed water regulator controls the flow of feed water, but does not prevent pulsations.
C) A reed valve is used to control the intake of the pump, not the discharge side.
D) A relief valve is used to release excess pressure, not prevent pulsations.
