Boiler Feed Pumps.
On a coal fired boiler at least two (2 ) feed pumps are required.
Should one feed pump fail, there is a stand-by pump available to ensure a continuous supply of water.
Your stand-by pump should be tested at least once a day/shift or preferably the feed pumps should be rotated on a regularly basis, with each pump being put into service on a weekly basis.
Should a pump fail it must be either replaced or repaired immediately, in case the other pump should also fail. Should both pumps fail for any reason, your fires must be dumped immediately and the Main steam stop valve ( Crown Valve ) closed, to save any water remaining in the boiler.
The feed pumps should of course always be kept in peak condition.
The boiler feed pumps must deliver a pressure of at least one and a half times the boiler pressure, that is with a boiler pressure of 1000Kpa the feed pumps should deliver at least 1500Kpa.
