Condensate carry-over in a boiler is related to the supply of wet steam, which contains water droplets. The formation of this type of steam is undesirable, as it is contaminated steam and is associated with the boiler operating incorrectly or with poor water quality. The solids carried over are usually sodium salts or caustic soda.
These carry-overs affect the wall of the boiler steam chamber, and lead to irregularities in the water level in the chamber.
Analysis of the water entering the boiler's steam circuit must be very precise to detect impurities and prevent condensate carryovers. It is possible to have auxiliary installations to improve the quality of the supply water and condensate recovery mechanisms, such as tanks containing ATTSU's WTC boiler water treatment plant.
