Measuring Water Hardness - Hardness Testing Products

Hard water is water that has high mineral content (as opposed to "soft water"). Calcium is the most common mineral associated with water hardness. While hardness is not generally a health hazard it can pose serious problems in industrial settings, where water hardness is monitored to avoid costly breakdowns in boilers, cooling towers, and other

Scaling in boilers - Lenntech

Scaling in boilers. 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.

Properly Treat Boiler Water for Efficient, Long -Term

Water treatment recommendations vary depending on the operating pressure of the boiler, the application (steam or hot water), and other parameters. General guidelines to prevent corrosion and scaling in low pressure boilers are as follows: Total Hardness 1 PPM Maximum . Total Alkalinity 600 PPM Maximum . Total Silica 150 PPM Maximum

Characteristics of boiler feedwater - Lenntech

Characteristics of boiler feed water. A low-pressure fire-tube boiler can usually tolerate high feed-water hardness with proper treatment while virtually all impurities must be removed from water used in some modern, high-pressure boilers. Only relatively wide ranges can be given as to maximum levels of alkalis, salt, silica, phosphates etc

Basics of Marine Engineering: BOILER WATER

Nov 29, 2012 · Blow Down practises - Blowing down boiler water helps limit the concentration of scale forming minerals/salts; Prevention of Condensate Loss - Condensate water is very pure and free from hardness causing minerals. Make up water on the other hand has impurities. As learnt before Boiler Feed Water is the sum of make up water and condensate water.

Operation of Boiler and Conductivity in Drum Water and

Feed water and boiler water need monitoring as any impurities in them gets concentrated and gets carried over in the steam. Conductivity has to be checked before and after the cation column, extraction pump discharge, economizer inlet, hotwell, and make-up treated water outlet. In all these places the conductivity is to be maintained within limits.

Water Treatment Storage and Blowdown for Steam Boilers

Boilers, however, are less able to cope, and these same minerals will cause damage in a steam boiler if allowed to remain. Of the worlds water stock, 97% is found in the oceans, and a significant part of that is trapped in the polar glaciers - only 0.65% is available for domestic and industrial use.
