water tube steam boiler

The boiler adopts a double-drum longitudinal "D" type arrangement structure; water, steam or steam-water mixture flows in the pipe; flame burns and flue gas flows outside the pipe, forming extremely fast steam-water.

Scale and sludge formation in boilersEngineering Chemistry UNIT-1-WATER CHEMISTRYEngineering Chemistry UNIT-1-WATER CHEMISTRYIf 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.

Water Handbook -Boiler Deposits: Occurrence And …Sludge is the accumulation of solids that precipitate in the bulk boiler water or enter the boiler as suspended solids. Sludge deposits can be hard, dense, and tenacious. When exposed to high heat levels (e.g., when a boiler is drained hot), sludge deposits are often baked in place.Engineering Chemistry UNIT-1-WATER CHEMISTRYSludge & Scale formation In a boiler, water is continuously evaporated and converted into steam.

How to Prevent Hard Scale Buildup Inside Boilers | Miura …

Elements contained in hard water, like calcium and magnesium, form a buildup on the components of the boiler. Preventing 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
