Q1:

Function of feed check valve in a boiler is to

A facilitate circulation of high pressure feed water.

B check the water level in the boiler drum.

C prevent the back flow of water.

D regulate the water flow to boiler.

ANS:C - prevent the back flow of water.

The function of a feed check valve in a boiler is to prevent the backflow of water. This valve ensures that water flows in only one direction, typically from the feedwater supply into the boiler. By preventing backflow, the feed check valve helps maintain the proper flow of water into the boiler and prevents any potential damage or disruption caused by water flowing in the wrong direction.
