      On the issue of sludge and scale formation in a steam boiler

      If the pH of the boiler water is higher than 11.5 and at the same time the boiler water is transparent, this fundamentally indicates the absence of sludge formation processes in the boiler. At the same time, if the pH of the boiler water is from 8.5 to 9.5 and the water is transparent in most cases this indicates an active scale formation in the boiler, and requires emergency measures.

      Only pure water leaves the boiler as steam is produced; any dissolved solids are left behind. Even though the condensate is pumped back into the boiler, some is inevitably lost and must be replaced with make-up water. Over time, the concentration of dissolved solids from the make-up water increases in the boiler as pure water is removed as steam.
