    2020/4/12 · Common issues found on Boiler feed water due to scaling. If the inside of a boiler is scaled, there is a great risk that the boiler material will overheat, leading to tube failure. The efficiency of operation will also be adversely affected. Hardness in the feed water will usually present problems in relation to the operation of boilers.

    2021/5/19 · Scale can cause lots of problems in steam boilers, especially if it's a process-steam boiler and some or all of the condensate gets dumped (think bakeries). Lost condensate means lots of fresh, cold feed water, and that brings in the calcium and magnesium, which will cling to the hottest surfaces of the boiler, slow heat transfer, raise fuel bills, and cut years from the life …

  • How the scale and sludge is formed in boiler? - Answers

    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 …
