On the Issue of Sludge and Scale Formation in a Steam Boiler

On the Issue of Sludge and Scale Formation in a Steam Boiler

Water-chemical mode of steam boilers using reverse osmosis desalination plants.

Having worked for many years with water-chemical modes of steam boilers of low and medium pressure, I have noticed that even if the feed water does not meet all the requirements of the boiler manufacturers, it does not always lead to failure of the boiler (damage to the heating surfaces of the boiler by corrosion or overheating due to salt deposits).

In this case. the economic performance of the boiler will deteriorate, there will be an increase in purge, more frequent replacement of equalizer glasses, frequent cleaning of sensors, etc. But boilers can work at insufficient quality of feed water for at least not less than the established service life. This often happens in industries where due to the specifics of the products there is insufficient attention to the boiler and proper operation and laboratory control are not carried out.

However, boilers are working during their service life in some industries and even longer, while others quickly fail.At the same time, the quality of feed water in both cases leaves much to be desired. Let's try to figure out what cases and what parameters are critical for the operation of the steam boiler, and what parameters, even if they are exceeded, allow you to operate the equipment.
