Scaling in boilers - Lenntech

Causes, and prevention of scaling in boilers, type of scaling. 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.

Tube Failures in High Pressure Boilers

Whatever the type of fuel being fired, all high pressure boilers are bound to have a tube failure during the course of their working life. Did you know that a single tube failure in a 500 MW boiler requiring four days of repair work can result in a loss of more than $1,000,000 apart from the generation loss?
