The Importance of Condensate Return Treatment | WaterWorld

In the power industry it is well known that condensed steam from the turbine/generator must be maintained at high purity to prevent corrosion and scale formation in the boilers. But what about condensate return at other industrial facilities, where most or all of the steam is utilized for process heating, and where the steam generators may be at lower pressure than typical utility boilers?

DRAFT BOILER/FEEDWATER GUIDELINES

In a steam boiler system, there are three potentially destructive elements: oxygen, carbon dioxide, and solids. 2.2.2 As the boiler water is heated and changes to steam, free oxygen is released, carbon dioxide is released from the solids, and the solids drop out (precipitate). 2.2.3 As the steam is used in the end process, it cools and condenses

Prevention of corrosion in steam boiler systems

Prevention of corrosion in steam boiler systems. This would drive the pH down and will cause corrosion in the condensate lines and equipment. The best way is to use amines to neutralize the pH and further bring it up to at least above 8.8. The feed rate would be targeted to

steam condensate Water Technology Report

Mar 13, 2017 · Historically, steam condensate has been viewed as the best quality water in the energy center. Pure condensed steam has all the characteristics of distilled water, i.e. low concentrations of dissolved and suspended solids as reflected in very low specific conductance and filterable residue.

Neutralizing Condensate in Condensing Boilers and Hot

When your boiler or hot water heater is operating in full condensing mode, approximately one gallon of condensate gets created for every 100,000 BTUs of input. So if your system runs for 1,200 hours each year, it will produce 1,200 gallons of condensate! The acidic level of the condensate is measured in pH on a scale from 0 to 14.

Managing Condensate for Condensing Boilers - Automatic Heating

Flue gas starts to condense when it drops below its dew point of 55°C. This is why condensing boilers are designed to accommodate a return water temperature of 54°C or less. It is this resulting condensate liquid that is acidic and requires treatment to avoid damage to piping systems, sewerage systems and other items it may come in contact with.

Why is steam condensate corrosive? Akvante

Oct 22, 2017 · The main reason for treating the steam condensate is to prevent corrosion. Corrosion will destroy condensate pipes and will generate corrosion products which will negatively affect the operation of the boiler system, especially if part of the condensate is recovered to be used as boiler feedwater. Why is condensate corrosive?

Steam and Condensate - A basic overview of a steam system

These, or electric powered pumps, are used to lift the condensate back to the boiler feedtank. A mechanical pump, see image on the right, is shown draining an item of plant. As can be seen, the steam and condensate system represents a continuous loop. Once the condensate reaches the feedtank, it becomes available to the boiler for recycling.
