If you want to know how much carbon dioxide the steam and condensate in your boiler room contain, you can use my article, which provides the formulas (16) and (18) to calculate the concentration of carbon dioxide in the steam for the working boilers and the ones which are still being designed.This can help to understand the nature of the acidity of the condensate and how to deal with it.
The current method of determining the amount of carbon dioxide in the steam does not take into account the fact that the hydrolysis of carbonates occurs simultaneously with the decomposition of bicarbonates.As the result of the calculation by this method, the amount of carbon dioxide in the steam is often understated compared with the real values. This article proposes an alternative method for calculating the concentration of carbon dioxide in steam, and shows that the use of water treatment technologies that reduce the alkalinity of make-up water are extremely important to reduce the corrosion aggressiveness of steam and condensate.
In the design and operation of low-pressure steam boilers there is a number of significant difficulties in the organization of water-chemical mode (WCM) of their work.
Water-chemical mode (WCM) of operation of a steam boiler should ensure trouble-free and cost-effective operation of the equipment and pipelines of the boiler.
WCM of a boiler is to maintain a certain composition of feed, make-up, boiler water, steam and condensate, which does not cause damage to the boiler equipment or its inefficient operation.
