1ppb for O2 and CO2
the pH value in boiler feed water is 9.2
Boiler feed pumps are an important part of any boiler operation. They control the amount of water fed to the boiler and the manner in which it is fed.
Boiler feed is the fresh or treated water to replenish the water loss though evaporation or leak
deaerator is a device used to remove dissolved oxygen and carbondi oxide in boiler feed water. it causes scaling inside the boiler tubes and economizer also.
A digester feed pump forces water to a boiler. It works by transferring cool water to the boiler to be heated.
Di ethyl Hydroxylamine, Hydroquinone
Function - It adds the pressure to the feed water before it entyers into boiler feed pump suction Advantage - Ensures high margin NPSH A for boiler feed pump spinning at high rpm (5250Rpm) Drive for booster - Normally @1450 rpm Type of impeller- Mostly preferred Double suction
Oils and water are not miscible.
In boiler feed water line the NRV is normally installed between Pump and stop valve if the line is short and an another NRV is installed at boiler entrance and after stop valve if the line is long or pump is 10 to 15 m away from the boiler.
dear, both morpholine and hydrazine or ammonia are used in conjunction. morpholine is a base which is used for adjusting the PH of boiler feed water.

The boiler feed pump pumps hot feedwater into the boiler. The boiler pressure is to high for water to flow into it by gravity, so a pump is required.
