Hardness - Hard water does not foam. However, boiler water is deliberately softened to prevent scale formation, and this gives it a propensity to foam. Colloidal substances - Contamination of boiler water with a colloid in suspension, for example. milk, causes violent foaming. Note: Colloidal particles are less than 0.000 1 mm in diameter, and can pass through a normal filter.
Jan 18, 2016 · While hard water may not be harmful to you directly, it can cause a number of problems with your plumbing system and appliances using water, including your boiler. The minerals in the hard water can lead to scale building up within your boiler. You may notice that you hear a rumbling sound coming from your boiler. This could be the result of scale building up within the burner, and the water
The hardness of water is caused by calcium and magnesium ions which will vary greatly throughout the country depending on the source of the water. In boilers the hardness of the water can cause the formation of scale and sludge or mud. The hardness must be removed in the makeup water to the return system. Total hardness should not exceed 50 PPM.

Nov 11, 2013 · The boiler could suffer from corrosion on the sides. The build-up could interfere with flow through the pipes, retarding the heating process considerably. In some cases, it can also serve as unwanted insulation against the heating, forcing your boiler to work harder in order to heat the water to the temperature it needs to be. You can prevent this by ensuring that the water you use has been
The quality of feedwater required is dependent on boiler operating pressure, design, heat transfer rates, and steam use. Most boiler systems have sodium zeolite softened or demineralized makeup water. Feedwater hardness usually ranges from 0.01 to 2.0 ppm, but even water of this purity does not provide deposit-free operation.
