Caustic corrosion in boilers - Lenntech

2. the boiler-water must contain caustic, 3. at least a trace of silica must be present in the boiler-water, and. 4. some mechanisms, such as a slight leak, must be present to allow the boiler water to concentrate on the stressed metal. Stem blanketing is a condition that occurs when a steam layer forms between the boiler water and the tube wall.

Boiler feed water - Lenntech

A boiler is a device for generating steam, which consists of two principal parts: the furnace, which provides heat, usually by burning a fuel, and the boiler proper, a device in which the heat changes water into steam. The steam or hot fluid is then recirculated out of the boiler for use in various processes in heating applications.

Scaling in boilers - Lenntech

Boiler scale is caused by impurities being precipitated out of the water directly on heat transfer surfaces or by suspended matter in water settling out on the metal and becoming hard and adherent. Evaporation in a boiler causes impurities to concentrate. This interferes with heat transfers and may cause hot spots. Leading to local overheating. Scaling mechanism is the …
