Why is used the balancing line in boiler feed pump and its direction of flow?
Wiki User
∙ 12y ago
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 difference between radial flow turbine and axial flow turbine?
in a radial flow turbine the steam enters the turbine in the direction of its radius and leaves it in the direction of the axis of the shaft. in a axial flow turbine the steam enters the turbine in the direction of the axis of the shaft and leaves the turbine in the same direction.
What flow is equal to and opposite of electron flow?
The "flow of current" is considered to be in the opposite direction.
What is theFunction of arc valve in boiler feed pumps?
The ARC valve provides protection for centrifugal pumps during low flow conditions. It recirculates a minimum flow requirement automatically to the deaerator to prevent the pump from overheating and causing internal damage. Pump manufacturers will dictate a pump's minimum flow requirement. The ARC valve will be designed to flow normal capacities through the main valve and also size the bypass to handle the minimum flow. Additionally, the flow sensing element, a disc, also acts as a check valve to prevent reverse flow to the pump.
The expression alternating current refers to which form of energy?
Alternating current is a flow of electrical energy in which the direction of electron flow reverses periodically. The mains electricity in your house is likely Alternating Current. The other form is Direct Current, where the direction of electron flow is in one direction only. Such as the flow from the batteries in your flashlight.
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.
Are winds named for the direction they flow to or the direction they flow from?
flow to
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 focus for a process improvement exercise on balancing?
Flow
In which direction does the river shannon flow?
in which direction does the river Shannon flow?
Why boiler drum level control is 3 element control?
three element means 1) drum level transmitter. 2) main steam flow transmitter. 3) feed water flow transmitter . in squared root. we are controlling drum level by these 3 elements. output feed to 30% control valve. or control valve.
High pressure steam boiler feed water p and id?
Usually high pressure boiler feed water is a 3 cell control using the drum level transmitters average, Steam flow Transmitter and feed water flow transmitter The drum level controller is tuned so that the drum level is around the half glass depending on load using the steam flow as a feed forward & drum level trim (lifting the drum level above SP under high load and lowering drum level under SP for low load)and the water flow to balance out with the steam flow (mind you if you blow down or have a tube leak the drum level will open the feed water control valve to maintain level) the main tuning in the P.I.D for this is Gain and integral not using derivative as it is too abrupt in its response obviously the actual full control schematics is a lot more complex than this
What direction do fluids flow?
Downward, Downriver, Downhill, the direction gravity pulls everything.
What altitude there will be a change in the direction of blood flow?
Blood flow doesn't change direction. They always head for the same direction.
In what direction does lymph flow?
The direction of lymph flow is always towards the Thoracic Lymph duct .
Axial flow turbomachines?
These are machines dealing with fluids, like (Axial Compressors, pumps and Fans). the term "Axial" is given due to the direction of inward and outward flow. In axial turbo machines the direction of outward flow is the same as the direction of the inward flow since the blades of the machines doesn't change the direction of flow.
Can you install a diode to allow 24 volts AC to flow in one direction but not allow the flow of 24 volts AC to flow in the opposite direction?
Diodes convert AC into DC by allowing current flow in one direction only. Since AC is alternating between plus and minus it is not possible to use a diode to allow AC to flow in one direction and not in the other direction.
