## The process through which the dissolved gases are removed from water is called the “Deaeration Process”. The equipment, which is used in this method, is called “Deaerator“. # Why do we use deaerators?… The Deaerator (DA) tank uses steam to preheat boiler feedwater to a temp. at which dissolved O2 & CO2 will become separated from the feedwater before it is pumped to the boiler. The purpose is to protect the boiler and steam/condensate piping from corrosion that would be present when the water evaporates into steam. An additional benefit is that the number of chemicals used to treat the boiler water can be reduced. #water #watertreatment #saftey #boilers #explotion #hazard #plant #construction #construction techproces.com/deaeration-process/
You see to the right that’s actually smoke going out the chimney system and the steam is actually being caused by the heat of those fire tubes … if the water level is too high tho you’ll get water going through the pipes instead of steam and if the water was too low .. well… I don’t think I need to tell you how bad that can be 😂 aha but nah I can see where you might have gotten confused but no that’s smoke being expelled through the roof and the steam is contained inside the boiler itself and then automatically released through the main valve up top
Wait what is going thru those grey moving matter having pipes if it isnt STEAM or water? Is that just hot air being pushed? If so why does it create SMOKE at whatever a smoke box is?!
This design is a fire tube boiler. The tube contains hot air that heats up the water in the vessel which generates the steam. The smoke is most probably from burning of the fuel e.g. coal which flows through the tubes and passes through the economizer.
Im so confused - isnt it missing the most important part - the part where there is showing water and steam together in a vessel and the steam touching and rising above the water?!
Yep as you see the fire is going through tubes that are in water.. where as a water tube boiler is the exact opposite.. water in tubes being heated by surrounding fire 😊 I’m new too only 3 days into know boilers even exist 😅😂😂
