Boiler Scale One of the most common deposit problems is boiler scale. This happens when calcium, magne­ sium and silica, common in most water supplies, react with tube metal found in boilers to form a hard scale on the interior of the boiler tubes, re­ ducing heat transfer and lowering the boiler’s ef­ ficiency.

HRSGs for small plants - Rentech Boile

Size matters, or so it seems. Take heat-recovery steam generators, for example. Mention “HRSG” and most people in the power business think of triple-pressure units in service at large combined-cycle plants. Articles in the trade press and papers presented at major industry conferences focus on these units.

boilers are the most used type of large volume boilers. Also electric boilers where water is heated with an electrode source can be considered large volume boilers. However, large volume boilers are today used for small-scale steam and hot-water production only and, overall, they are not common in large-scale industrial use anymore. [1]

SOME COMMON MECHANISMS LEADING TO FAILURES IN HEA

SOME COMMON MECHANISMS LEADING TO FAILURES IN HEA

The presence of an iron-based deposit in the boiler often creates the conditions where over concentration of the boiler water in the deposit can result in high concentrations of sodium hydroxide leading to caustic attack. In HRSG systems deposition is usually in the form of metal oxides. The source of the metal

Scaling in boilers - Lennte

Scaling in boilers - Lennte

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.

It can take two forms: caustic gouging or caustic cracking, also called caustic embrittlement. Caustic attack or caustic corrosion, is often encountered in phosphate treated boilers in which deposits of phosphates or other ‘scale’ occur in high heat transfer areas. Boiler water can permeate the porous deposit resulting in localize corrosion.
