70% to pass

The boiler main feed stop check valve is located nearest the _______________.

ADC heater feed water outlet
Bboiler water drum inlet
Cfirst stage feed water heater outlet
Dmain feed water regulator inlet
AI Explanation

The correct answer is D) main feed water regulator inlet. The boiler main feed stop check valve is typically located nearest the main feed water regulator inlet to ensure that the feed water flow can be isolated and controlled before it enters the boiler. This allows for proper regulation of the feed water supply, which is crucial for the safe and efficient operation of the boiler. The other options are not correct because they do not represent the typical location of the boiler 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 nearest locations to the main feed water regulator inlet where this critical valve would be placed.
