Feed Water and Steam Circuit of Boiler | Electrical4U

04/03/2020 · 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 saturation temperature corresponding to the boiler pressure. Throwing away the flue gases of high temperature into the atmosphere involves a great deal of energy losses.

Proper treatment of boiler feed water is an important part of operating and maintaining a boiler system. As steam is produced, dissolved solids become concentrated and form deposits inside the boiler. This leads to poor heat transfer and reduces the efficiency of the boiler. Dissolved gasses such as oxygen and carbon dioxide will react with the metals in the boiler system and lead to boiler corrosion. In …

how a boiler feed water system affects your boiler


11/08/2020 · Dissolved gases are mostly driven out of feed water in the Deaerator or hot water tank. The proper function of these systems is essential to preventing corrosion both in the boiler room and in the steam system. Careful attention is required to ensure that gases can be safely removed from the boiler water prior to feeding the boiler.

In case of a feed system in an auxiliary boiler, as found on diesel propulsion ships, the drain tank or the hot well is open to the atmosphere. While in a high pressurized system, no part of the system is open to the atmosphere. A feed system, is nothing but a cyclic process that takes place between the turbine and the boiler. This cyclic process facilitates the exhausted steam to return to the boiler in the form of …

26/09/2016 · After the softening process, some boiler feed water treatment systems will utilize dealkalization to reduce alkalinity/pH, an impurity in boiler feed water that can cause foaming, corrosion, and embrittlement. Sodium chloride dealkalization uses a strong anion exchange resin to replace bicarbonate, sulfate, and nitrate for chloride anions.
