What is the function of feed pump in boiler?
Boiler Feed Pumps are designed to handle the amount of pressure your operation needs. Boiler feedwater pumps transport water into boilers using high pressure. Thus, a boiler feed pump is built to handle extremely high water pressure to deliver the feedwater into the boiler system.
How do feed pumps work?
The work of a boiler feed pump is to discharge the condensate boiler feed water from hotwell to the boiler drum. With the rotation of shaft and impeller the hot feed water is thrown outwards radially across the walls of the pump; along the path of the flow. This increase the speed of the fluid so does the pressure.
What is the function of the feed water pump of a boiler 2 points?
Explanation: Function of feed water pump is to pump water at high pressure to the water space of the boiler drum.
What temperature is boiler feed water?
between 185 and 195°F
The temperature of the feedwater tank should be maintained between 185 and 195°F (85 and 90°C) to reduce the amount of oxygen in the water. By increasing the temperature and reducing the oxygen content, you can greatly reduce your sulfite or oxygen scavenger requirements.
What is a boiler feedwater pump?
Boiler feedwater pumps transport water into boilers using high pressure. Thus, a boiler feed pump is built to handle extremely high water pressure to deliver the feedwater into the boiler system. Generally, a boiler feed pump can handle the pressure of up to 100 bar.
What is a feed pump and how does it work?
A feed pump is a type of pump that supplies water to a boiler to produce steam. For industrial purposes, a feed pump supplies a liquid for further processing. These pumps are high-pressure pumps and are generally of two types:
What is a boiler impeller and how does it work?
Multiple impellers are used in series to generate the high pressures necessary to feed the boiler. Sometimes referred to as Between-Bearing Pumps (BB Pumps), bearings on each end support the shaft of the pump. The impellers are in between the bearings.
What type of pump is used in a package boiler?
Auxiliary boilers, requiring only small amounts of feedwater, may use a reciprocating positive displacement pump, which is driven by the steam produced from the boiler itself. Another type of feed pump often used for package boiler installations is an electro-feeder. This is a multi-stage centrifugal pump driven by a constant speed electric motor.
