Boiler Scale - How To Clean Scale Off Of Your Steam Boil
When scale precipitates and forms within the boiler system, it can cause an isolating effect, which increases temperature variations. These increased variations can result in leaks in a boiler tube, or in extreme cases, boiler tube rupture. Another effect of scale formation is seen in heat transfer efficiency.

What is scale formation in case of a boiler? - Quo
Water contain minerals in oxide form. These salts at higher steam temperature stick to boiler tubes from inside. This is scaling. Further they keep depositing and keep reducing flow area. Salts mainly get deposited in curved tubes. So water used i
Details
Boiler water is liquid water within a boiler, or in associated piping, pumps and other equipment, that is intended for evaporation into steam.The term may also be applied to raw water intended for use in boilers, treated boiler feedwater, steam condensate being returned to a boiler, or boiler blowdown being removed from a boiler.
Details
Observing all of the above losses which are resulted out of boiler scale formation, it is very important to avoid the scale formation. On financial fronts, scales and deposits can aggravate following costs/ losses-1. Higher maintenance costs. 2. High repair costs in case of tube failures. 3. Down times which can affect the production line badly. 4.

Difference between Scale and sludge - Answe
When water converts into steam conc of dissolved salt inc, after reaching a saturation level the salts are thrown out in form of ppts. This is sludge.while scale is a hard and adherent deposit on

Corrosionpedia - What is a Sludge? - Definition fr
Sludge reduces heat efficiency and may cause scale formation in boilers and heat exchangers. Boiler sludge is a deposit that forms when suspended materials present in the boiler water settle on, or adhere to, hot boiler tubes or other surfaces.

Details
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.

EC: Lesson 11. Scale and sludge formation in boile
(2) Lowering of boiler safety : Due to scale formation, over-heating of boiler is to be done in order to maintain a constant supply of steam. The over-heating of the boiler tube makes the boiler material softer and weaker and this causes distortion of boiler tube and makes the boiler unsafe to bear the pressure of the steam, especially in high-pressure boilers.
