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 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 Boiler feed pump?
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
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 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.
What is the PH value in boiler feed water?
the pH value in boiler feed water is 9.2
