Pressurised Deaerators | Spirax Sarco

Due to the rising cost of chemical treatment, it is proposed that a pressurised deaerator be installed, operating at 0.2 bar g to raise the feedwater temperature to 105°C, reducing the solubility of oxygen to quantities typically measured in parts per billion. Steam, produced in the boiler at 10 bar g, is to be used as the heating agent.

Deaerator - an overview | ScienceDirect Topics

The pressure in the deaerator varies according to the turbine extraction steam pressure from a particular minimum load up to the full load. During start-up, steam to the deaerator is usually supplied from an auxiliary steam header and deaerator pressure is maintained at a pre-assigned minimum constant pressure, typically about 0.15 MPa. Once the machine is loaded, the pressure in the cold

How to size a condensate return unit - Xylem Applied

2015-5-20 · Knowing how much water, or water as steam, the boiler can put out is good, but don't pick a pump size yet. ASHRAE recommends sizing your return pump for two to three times the boiler's evaporation rate—so the return unit can return condensate faster than the boiler can put it out. If that vessel is a pressurized deaerator, you have to

Deaerator Selection: Atmospheric or Pressurized

2021-3-9 · A pressurized unit should be considered whenever there are trapped returns to the deaerator. The pressurized system which uses the flash steam from the trapped returns for feedwater heat is the best choice. A constant recycle system is the best choice. Steam turbine exhausts are another reason to use a pressurized system.
