function of steam boiler for feed

Chapter 10 Boiler Feedwater Deaeration | SUEZ

In order to deaerate the boiler feedwater, water is sprayed into a steam atmosphere. This heats the water to within a few degrees of the temperature of the saturated steam. Because the solubility of oxygen in water is very low under these conditions, 97 to 98% of the oxygen in the incoming water is released to the steam and is purged from the

Boiler Feed Water Pump Working Principle and Operation

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).
