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

∙ 11y agoTo feed the boiler, two in nos feed pump provided, one is in use and one in no kept standby while the boiler is in use. It is supply the water (feed Water) to the boiler, where the heat is generated and boiler produced steam for the main propulsion and domestic use on board ship and industries.

In boiler feed water line whether a non return valve should precede or succeed the delivery valve of feed water pump?
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.
What is boiler feed water?
Boiler feed is the fresh or treated water to replenish the water loss though evaporation or leak
Why you use boiler in oil refinery?
Use of water in a refinery is makeup for boiler feed. The chief uses of steam are for stripping, steam distillation, and vacuum distillation. The steam comes in contact with the products in these operations, and generally the steam condensate is so highly contaminated that it cannot be reused for boiler feed or for other purposes. Steam is also used for process heating, for pumping, and, in some refineries, for generating electric power
Why is the boiler water circulating pump required for EGB?
I think because it works more like a heat exchanger taking heat from the exhaust gas, rather than a "standard" boiler with a furnace?An EGB needs a pump to circulate the water through the pipes in the exhaust stack, whereas a furnace-heated boiler can use convection to move the fluid through the system..?Might have something to do with lower temperatures in an EGB?
What is boiler corrosion?
the decay of boiler material by chemical or electrochemical attack by its environment is known as boiler corrosion
What is digester feed pump?
A digester feed pump forces water to a boiler. It works by transferring cool water to the boiler to be heated.
What is float in boiler feed pump?
it is 500N
What is the use of boilerfeed pump?
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.
What is boiler feed water pump?
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.
What is the Use of Balancing line in Boiler feed pump?
Boiler feed pump's suction pressure be aprox. 15Kg/cm2 and discharge pressure be 180Kg/cm2. So the balancing line balance the pressure and protect the boiler feed pump. my quastion is that what is the working principal of balancing leak off
What is TDBFP?
TDBFP = Turbine Driven Boiler Feed Pump
How do you calculate Boiler feed pump efficiency?
Pump efficiency can not be taken as given.
In boiler feed water line whether a non return valve should precede or succeed the delivery valve of feed water pump?
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.
What is the Use of Balance leak off line in Boiler feed pump?
avoid thrust
Why is used the balancing line in boiler feed pump and its direction of flow?
In boiler feed pumps usually the discharge pressure is 20 to 30 times tie suction Pressure so to protect the pump balancing line is given from discharge to suction.
What is the PH value in boiler feed water?
the pH value in boiler feed water is 9.2
What is the function of back pressure valve in Boiler feed pump?
The function of back pressure valve is to prevent back flow to the pump in case there is an obstruction on downstream side of valve.
