Question 101Steam Plants - QMED70% to pass
When operating with the auxiliary feed line, feed water flow is controlled _______________.
AI Explanation
The correct answer is C) manually by throttling the auxiliary feed stop-check valve.
When operating with the auxiliary feed line, the feed water flow is controlled manually by adjusting the auxiliary feed stop-check valve. This allows the operator to throttle the valve to control the desired water flow rate to the boiler, rather than relying on automatic controls.
The other options are incorrect because: A) the economizer bypass does not control the auxiliary feed water flow, B) the auxiliary feed water regulator spring setting is not adjusted to control flow, and D) the main feed water regulator controls the main feed line, not the auxiliary feed.
