MgCl2 is soluble under normal boiler condition but can do some extent break down inside the boiler to form Mg(OH)2 and HCL –this can set up an active corrosion with in the boiler metal.

BOILER PROBLEMS - SlideShare

Mar 12, 2016 · Priming can be avoided by (i) controlling rapid change in steaming velocities. (ii) the proper design of boilers (maintaining low water levels in boilers). (iii) ensuring efficient softening and (iv) filtration of the boiler-water carried over to the boiler. (v) by blowing off sludge or scales …

Small scale live steam frequently asked questions.

Jul 05, 2011 · So-called "small scale" live steam is actually on the large end of the usual model railroading spectrum, though most live steam equipment runs on much wider track (.75" scale or larger). There are quite a few different sizes and scales which fall into this category.

Foaming and priming in boilers - Lenntech

Boiler water carry-over is the contamination of the steam with boiler-water solids. Bubbles or froth actually build up on the surface of the boiler water and pass out with the steam. This is called foaming and it is caused by high concentration of any solids in the boiler water. It is generally believed, however, that specific substances such as alkalis, oils, fats, greases, certain types of

An Introduction to Treatment of Steam Boiler Water

Descaling agent | Article about Descaling agent by The

Calcium carbonate scale is commonly formed in a boiler system through exceeding the threshold solubility of the waters' mineral content. Most dissolved solids in water become soluble as the temperature of the water increases, and thus precipitates on heat transfer surfaces as scale. Oftentimes, the temperature of each boiler tube will vary slightly, and more scale tends to develop on these hotter …

Scaling in boilers - Lenntech

Scaling mechanism is the exceeding of the solubility limits of mineral substances due to elevated temperature and solids concentration at the tube/water interface. The deposition of crystalline precipitates on the walls of the boiler interferes with heat transfer and may cause hot spots, leading to local overheating.
