70% to passThe boiler main feed stop-check valve is located nearest the _______________.
Amain feed water regulator inlet
BDC heater feed water outlet
Cboiler water drum inlet
Dfirst stage feed water heater outlet
AI Explanation
You are correct, the answer is A) main feed water regulator inlet. The boiler main feed stop-check valve is located nearest the main feed water regulator inlet to control and monitor the flow of water into the boiler. This placement allows the operator to regulate the water level and pressure in the boiler by controlling the flow of water from the feed water system. The other answer choices are incorrect because they do not represent the typical location of the main feed stop-check valve. The DC heater feed water outlet, boiler water drum inlet, and first stage feed water heater outlet are not the primary control points for the boiler's main feed water system.
