What is the meaning of boiler feed?
Feedwater is water that undergoes purification or preheating and is then supplied to boilers for hot water and steam production, or it can remain still. It is typically found in thermal power plants where it is stored and conditioned in tanks, known as boiler feedwater.
Which pump used in boiler feed?
There are two types of pumps that are most often used for boiler feed water applications: stamped stainless steel vertical multistage inline pumps and multistage horizontal ring section pumps.
What is boiler feed pump DP?
through operation of the Boiler feed pump scoop control in auto mode by using the differential pressure method. • To reduce Power consumption of the Boiler feed. water system as Boiler feed pump is one of the equipments in a power plant with the highest auxiliary consumption.
How does a boiler feed water pump 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 a feed pump?
Definition of feed pump : a force pump for supplying water to a steam boiler.
What are the types of feed pump?
These pumps are high-pressure pumps and are generally of two types: Positive displacement type feed pumps. Centrifugal feed pumps.
What is the use of feed pump?
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: Positive displacement type feed pumps.
What is the function of feed pump in a boiler?
The boiler feed pump function is to supply pressurized feed water to the boilers maintain the water inventory at various operating loads. Boiler feed water pumps are commonly centrifugal pumps. To ensure a high enough head and pressure, Boiler feed Pumps have been arranged in series (multistage pumps).
How does a steam boiler feed pump work?
‘Boiler feed water pump’ pumps the water at high pressure into the boiler from the ‘feed water tank’. The pump is akin to the heart in the human body. ‘Feed water heaters’, using extracted steam from the turbine, adds a part of the sensible heat even before the water enters the boiler.
What is boiler feedwater pump?
6 Facts about Boiler Feed Water Pumps Boiler feed pumps are used to supply fresh water to a boiler. There are three components typically selected together: the boiler, the feed water pumps, and the deaerator. There are two different types of boilers: fire tube and water tube.
What is a steam boiler feed pump?
The boiler feed pump is a multistage centrifugal pump used to increase the discharge pressure of the feed water to the boiler. To deliver the feed water into the boiler steam drum, it has to raise the pressure beyond the boiler steam drum pressure.
