Boiler feed pumps are also referred to as feed pumps (see Reactor pump) and designed as multistage radial flow pumps. (Also see Multistage pump .) They serve to feed a steam generator such as a boiler or a nuclear reactor with a quantity of feed water corresponding to the quantity of steam emitted. Today all boiler feed pumps are centrifugal pumps.
The main feed check valve functions to _____. a) check pressure pulsations in the feed line b) prevent backflow of water from the boiler in the event of a feed pump failure c) provide feed pump positive discharge head d) reduce pump discharge pressure loading
Water softeners are a common piece of pre-treatment equipment for boiler feed water. Water that is too hard quickly scales up the internal components of a boiler making heat-exchange far less efficient and eventually destroying the . softeners also significantly reduce or
