Web(e) Effect on steam generation in boilers: For steam generation, boilers are almost invariable employed. If the hard water fed directly to the boilers, there arise many troubles such as: ( i) Scale and sludge formation, ( ii ) corrosion ( iii ) priming and foaming, and carry over, ( iv ) caustic embrittlement. WebPreventing this damaging accumulation of hard water deposits is crucial to maintaining the effectiveness of a boiler. Hard scale buildup, even a seemingly insignificant one of 1/8 of an inch, can reduce efficiency by up to 20-25% due to lost heat transfer. That translates to escalating costs to operate your boiler room.
WebThe formation of deposits such as scale and sludge in a boiler system results in elevated metal temperatures, causing tube failures and restricted circulation. Boiler system corrosion leads to localized pitting and/or thinning of pipe and …
