Thermal degassing (pressure degassing) of boiler feedwater requires that the water be boiling. The mixture of condensate and fresh water is fed into the degassing dome at the top. Heating up to the boiling temperature occurs with heating steam, which flows into the degassing unit at the bottom and flows upward against the current.

2019-11-11 · A feed water heater is a device used to gradually heat water that is being delivered to a steam boiler. The main reason why feed water heaters are used is because the water needs to be heated gradually until it reaches its boiling point, also known as the saturation temperature.
It is the high purity water pumped into the boiler, to replace the water that is turned into steam.

2014-8-24 · They were now considering using sodium sulphite to reduce the oxygen. Dr. Douwes Dekker pointed out that the high pH of itself would lower the activity of the oxygen present. We had now been given the methods of analysis of boiler feed water. He hoped that at
Because the water in the boiler before boiler failure is at a higher temperature (and pressure) than boiling water would have been at ambient atmospheric conditions, some of the water will flash into steam as soon as the boiler fails and the vapor pressure above the water drops to ambient.
2017-3-20 · pitting can result with possible rupture of boiler condensate piping or boiler tubes. 3.3.4 Rusty water in the boiler gage glass is a sure sign of acid corrosion in the boiler feedwater/condesate system or in the boiler itself. 3.3.5 Make-up water is the major source of carbon dioxide. The first priority is to minimize the amount of make-up water.

2004-1-1 · Should a balance valve be throttled before the feed water valve of each boiler to equalize all the boiler pressure drops at full load conditions? Should this be done with a dummy steam load at start up, or could it be done by pressurizing the boiler before first firing and use cold water only and letting water to flow back to the deaerators?
In case the hot well overflows, the water goes to the feed water tank, which supplies feed water to the system whenever there is a dearth. A de-aerated type heater is used in the feed water line in order to remove any dissolved oxygen from the water. This is basically done to prevent corrosion of the boiler.
