The heating surface is any part of the boiler; hot gases of combustion are on one side and water on the other. Any part of the boiler metal that actually contributes to making steam is heating surface. The amount of heating surface of a boiler is expressed in square meters. The larger the heating surface a boiler has, the more efficient it becomes.
Water hardness; Boiler feed typically consists of alternating water softeners to allow a continuous feed of soft water. Because of the efficiency of boilers, capacity and not flow rate is the main issue in designing the water softener system. The higher the operating pressure of the boiler, the more stringent the water quality requirements will

When this regeneration is taking place, the resin cannot soften the incoming water supply. With two water softening tanks, when one of the tanks is in regeneration the other tank is fully functional and still provides your system with processed water. This method ensures a constant flow of soft water to your boiler
Therefore, water treatment is always required in the make-up water of a boiler. Water treatment of make-up water will depend on the source of water and boiler manufacturer requirements suspended solids removal, dissolved solids removal, softening, pH adjustment, dosing of biocides for bacterial control, dosing of anticorrosion agents.
Selecting a Softener To Match Your Conditions. A water softener valve contains moving parts but these parts only move when the softener is regenerating. Regenerating once-a-week also keeps the water consumption low; a water softener uses about 50 gallons when it regenerates.
Water-tube boiler plant. Water-tube boiler plant is much less tolerant of high TDS levels, and even less so as the pressure increases. This is due to a number of reasons, including Water-tube boilers have a limited water surface area in the steam drum, relative to the evaporation rate.
Water Softening Plant Amrita Water Solution Services
Dec 27, 2018 · Water Softening Plant This technique is ideally suited to treat water having hardness. The flow of water during opoartion and the flow of the brine (salt solution) used to regenerate the unit are opposite to each other. Treated water is produced with consistent, low residual hardness throughout the cycle. Applications Boiler feed Textile

Jan 16, 2017 · More recently, however, reverse osmosis (RO) has gained a strong foothold in producing boiler makeup. This is because RO offers several advantages over traditional water softening. This includes operating the boiler at lower blowdown rates, improving steam and condensate quality, and minimizing the consumption of boiler maintenance chemicals.
WATER SOFTENING PLANTS TO PREVENT LIMESCALE IN LOCO BOILERS
Aug 15, 2016 · I am trying to research water softening plants and how they were used in conjunction with railways tp prevent limescale in loco boilers. I assume the calcium sludge was taken away by rail .. any info gratefully received.
Aug 26, 2016 · Boiler water is the liquid phase of steam within a boiler. The term may also be applied to raw water intended for use in boilers, treated boiler feed water, steam condensate being returned to a boiler, or boiler blow down being removed from a boiler. Treating boiler feed water over 15 years.
Water Softening Plant The presence of hardness salts (calcium and magnesium ions) in the make up water supplies to boilers, cooling and process waters can have a serious impact on their performance. Loss of heat transfer in boilers and poor cooling in re-circulating cooling systems results in an increase in both energy and water consumption

To protect your critical assets (i.e boiler) where possible you need to be treating your incoming make-up water with a base exchange water softener to prevent scale by softening the water. Feedwater's rage of softening systems treat from 0m3 per hour up to the major
The Water Softening Process. Once water hardness is known, you have two options. You can live with the hardness level, recognizing that levels below 7.0 gpg will probably not cause major scaling and soap film, or treat the water to reduce the calcium and magnesium present.A water softener, also called an ion exchange unit, will effectively accomplish the latter option.
Pit water Effects of drought Condensate as feed water Water blending PART 2. SCALE FORMATION Effect of scale Lime-soda process Hot lime-soda softening General notes on plant Nuclear precipitation Caustic soda softening Sodium aluminate with lime-soda treatment Zeolite or base-exchange softeners Partial Zeolite softening
Industrial Water Treatment Boiler Feed Water RO Filtration
For hard water scale and deposits, a water softener will be required. To remove iron deposits or sediment, oxidation coupled with depth or multimedia filtration will work best. If bacteria or viruses are a concern, a reverse osmosis system plus UV sterilization and submicron filtration is commonly used.
Reducing water use softeners and reverse osmosis 03 Understanding where water is used in a softening plant To identify the water saving opportunities, you first need to consider how much water the softening process uses; and how much and where softened water is being used. Water used for regenerating ion exchange beds can be
