    Good engineering practice dictates that the boiler water be evaluated for embrittling characteristics. An embrittlement detector described in Chapter 14 is used for this purpose. If a boiler water possesses embrittling characteristics steps must be taken to prevent attack of the boiler metal.

    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. Sludge deposits hardened in this way can be as troublesome as .

    As the water removes heat from the tubes the water temperature increases and it rises to the boiler steam drum. Eventually sufficient heat is transferred and steam is generated. Colder feedwater replaces the water that rises which creates the natural circulation.
