Boiler feed water flow diagram.
Pre heating feed water heaters using extracted steam from the turbine adds a part of the sensible heat even before the water enters the boiler.
Figure 2 allows pressure drop in psi or ft.
The pump is akin to the heart in the human body.

Figure 3 is a process block flow diagram showing integration of a vibratory shearing system with boiler feed water treatment at an industrial manufacturing facility.
All valves numbers are preceded by bfd unless otherwise noted.
Of water to be calculated for a given flow and pipe size.
This valve opens towards the boiler only and feeds the water to the boiler.

The high pressure feed water is supplied to the boiler through this valve.
The treated boiler feed water is then fed to the boiler via a supply pump.
This is basically done to prevent corrosion of the boiler.
Boiler feed water pump pumps the water at high pressure into the boiler from the feed water tank.
Boiler feed water quality is limited owing to problems of 1 scaling 2 corrosion and 3 foaming.

This figure will work with either water flow in a hot water system boiler or feedwater to a steam boiler.

Like figure 1 working backwards will allow pipe size to be calculated for a target pressure drop.
The boiler size range pressures and types we will be addressing today methods and importance of capturing condensate for boiler feed typical pumps used for boiler feed water discharge typical piping methods used pump sizing criteria criteria for calculating the base flow for the pump understanding tdh and npsh.
There are different components present in feed water and steam circuit of boiler and we should know some essential components of these circuit and these are economizer boiler drums water tubes and super heater.
Economizer is a heat exchanger which takes heat from the flue gas and increases the temperature of feed water coming from feed water common header to about the.
The system also consists of a feed regulator which controls and maintains the level of water in boiler drum.
A de aerated type heater is used in the feed water line in order to remove any dissolved oxygen from the water.
In order to avoid these problems the quality guidelines shown in table iv have been adopted.
