Cleaning up the Confusion Surrounding Boiler Deslaggi

Cleaning up the Confusion Surrounding Boiler Deslaggi

With the acoustic cleaning setup, built-in speakers or horns create waves of sound that dislodge particulate. In boiler systems, these waves are used to loosen up dry ash buildup. Unlike a water jet or a blower, this type of boiler deslagging doesn't need to be aimed and directed. Instead, acoustic deslagging cleans the entire volume.

Deposits of a porous nature allow boiler water to permeate the deposits, causing a continuous buildup of boiler water solids between the metal and the deposits. Because caustic soda does not crystallize under such circumstances, caustic concentration in the trapped liquid can reach 10,000 ppm or more.

Corrosion, however, takes many forms and deep pitting that causes only a small amount of total iron loss causes penetration and leakage in boiler tubes. Corrosion beneath certain types of boiler deposits can weaken the metal and cause tube failure. Likewise corrosion in steam condensate system can damage pipelines and equipment. Corrosion ...

This type of boiler is able to supply water at a sufficiently high temperature and volume to meet the requirements of baseboard radiators, which typically need water to be about 180 degrees ...

Chapter 12 Boiler Deposits: Occurence And Control | SU

Most deposits can be classified as one of two types (Figure 12-1): scale that crystallized directly onto tube surfaces; sludge deposits that precipitated elsewhere and were transported to the metal surface by the flowing water; Scale is formed by salts that have limited solubility but are not totally insoluble in boiler water.

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.

PDF Characteristics of Water-Side Deposits in Boiler Tub

The formation of water-side deposits in drum-type utility boilers is a major concern to the heat transfer efficiency and availability of the unit. In recent years there have been major attempts made to correct the formation of deposits through the use of chemical clean- ing and the development of improved feedwater chemical treatment.

As what it can be made out from the image, this appears to be scale or calcium deposits in your electric boilers. Yes, the reason for these deposits is that the water supplied to your area is likely to be of the hard water kind. It has nothing to do with the quality of the electric boilers available to the UK in case you are doubting on it.
