Deaeration of high-viscosity viscoses
Fibre Chemistry, 1991-- Questions about the flow of highly viscous viscoses in evacuators of units for continuous deacration (CDU) have been examined.

Deaerator Inspection and Analysis
CORROSION 1987, 1987Abstract Inspection of 11 deaerator systems at the Savannah River Plant (SRP) was performed after at least 30 years of service. Each deaerator system consists of a heater vessel and a storage vessel. Of 22 total vessels, only 11 were found to contain cracks, and these were repaired.

Deaerators and Feedwater Heaters
2012Deaerators and feedwater heaters are important components of any power utility boiler condensate and feedwater supply system. Deaerators are found in all industrial plants using fired boilers for process steam production. Feedwater heaters of the type described here are usually found only in power generating plants using steam turbines as they rely on ...

Strategies for Coping with Cracked Deaerators
CORROSION 1988, 1988Abstract The weld cracking problem in deaerator systems in the pulp and paper industry (and other industries) has been well defined as corrosion fatigue cracking. In most cases the problem has been sourced to original weld defects and/or operating anomalies. Inspection is critical to find and define the extent of any cracking.

Reality Check: The Reinspection of Deaerators
CORROSION 1996, 1996Abstract Data generated from the reinspection of some six hundred deaerators are examined. They show that not all vessels that were cracked during the initial inspection were cracked in subsequent inspections. The repair technique influences the propensity for recracking.

Electrical Deaeration of Boiler Feedwater
Anti-Corrosion Methods and Materials, 1955This article describes a deaerator, developed in California, to furnish oxygen‐free water to low‐pressure boilers and hot‐water systems where other types are impracticable. Oxygen removal is accomplished by passing the water through a tank upon the surface of which hydrogen is deposited by electrolysis.

THE DEAERATION OF BOILER FEED WATER
Journal of the American Society for Naval Engineers, 1937As methods for treating boiler feed water have improved, and marine engineers have increasingly turned their attention to the need for greater cleanliness of the waterside, it is becoming apparent that there is a distinct possibility that modern cleanliness may not be an unmitigated blessing.

Deaerator Cracking - an Industry Update
CORROSION 1986, 1986Abstract The rupture of at least three deaerator water storage vessels, in one case involving fatalities, has prompted numerous industries to launch a pressure vessel inspection program which has yielded shocking results. This paper discusses some case histories of deaerator failures and describes the nature of the problem.
