In a boiler,
the feed check valve is used to :
Control the feed water flow rate
Check the
water level in drum
Ensure
unidirectional feed row to drum
Check quality of feed water
Control the feed water flow rate
Feed check valves
are one of the most important components of boiler which control the flow of
water from feed pump to the boiler and further prevents the backflow
of water from boiler to pump when the boiler pressure is more
than the pump pressure or when feed pump stops working.
Hence, the
correct option is (A).
