Regarding the pressure at the deaerator inlet
Thread Content
Dear experienced sea friends, I would like to ask whether there are any pressure requirements for the desalinated water entering the deaerator. Since there are nozzles inside the deaerator, surely there must be requirements regarding the inlet water pressure? Thank you all
I have a question. Since I have no prior knowledge of boilers, could you help explain the principles and operation of deaerators?
You can send an email; I can’t upload it here
There is no pressure requirement for the deionized water fed into the deaerator in our plant.
No specific requirements; operate according to the requirements of the make-up water pump. Principle: As the temperature rises near the boiling point, **the dissolved oxygen content in the water decreases
Deoxygenation in deaerators is divided into physical deoxygenation and chemical deoxygenation. Physical deoxidation: 1. This method takes advantage of the fact that dissolved oxygen in water decreases as the water temperature rises; it also improves the deoxidation effect by adding fillers at the inlet of the deoxidizer. Chemical deoxygenation: Dissolved oxygen in water is removed through a chemical reaction by adding hydrazine (N2H4) to the deoxygenator, where N2H4 + O2 = N2 + 2H2O.
Thank you. If the desalinated water pumped to the deaerator inlet is at exactly 0 MPaG or slightly positive pressure, will this ensure that the water mixes thoroughly with the steam?
It seems that ordinary people require 0.2 MPa
What is the purpose of adding packing at the feed inlet of the deaerator to improve the deoxygenation effect?
