Boiler Water Treatment - Scale Prevention

Boiler Water Treatment - Continuing our look at steam boilers and boiler water treatment problems we look at issues that surround the accumulation of hardness salts and preventing scale in boiler systems. We examine the problems caused by the accumulation of scale, hardness salts and how to prevent them using equipment and specialist antiscalants and scale inhibitors.

Preventing Scale & Hardness Salts

Hardness salts are the cause of scale inside a boiler; if they are not prevented or removed regularly they will cause localised overheating. This can lead to tube failure (explosion risk) and/or a reduction in the heat transfer properties of the transfer surfaces. This in turn leads to reduced efficiency and increased energy costs. Hardness salts can either be removed before they enter the boiler system, using a water softener, reverse osmosis plant or de-alkalisation unit, or they can be treated inside the boiler itself.

Equipment

Preventing Serious Scaling Problems

It is normally more cost effective to use equipment to remove hardness salts when the water hardness is high, however you should always complete your own calculations because even for soft waters it may be beneficial to use a water softener when considering blowdown requirements.

Phosphates & Carbonates

Once inside a boiler the hardness salts can be treated with phosphates or carbonates. Phosphates are preferred as carbonates can lead to an increase in the levels of carbon dioxide in the steam, and hence an increased corrosion risk.

Polymers

Together with phosphates, polymers should also be used to prevent salts precipitating and eventually 'baking-on' to surfaces.

Boiler Products

Accepta have a number of highly effective, technically advanced antiscalant products developed specifically for the treatment of boiler water, and which help to prevent corrosion problems:

Phosphate Boiler Water Treatment (Food Safe) - Accepta 2015 is particularly effective against calcium sulphate and calcium silicate. This product commplies with FDA regulations for steam that comes into contact with food. As 2015 does not discolour boiler water it is also useful in situations where coloured boiler water carry over may be problematic ... phosphate treatment (food safe) >>

Combined Phosphate and Polymer Treatment for Steam Boiler Systems - Accepta 2016 can be used in steam boiler systems up to 1500psi g. and acts as a combined antiscalant and suspended solids control agent. This product is excellent for softened and low hardness water. The phosphate reacts with the hardness whilst the polymer provides transport of calcium, magnesium, iron, phosphate and silica through the boiler, preventing scales adhering to metal surfaces ... phosphate polymer treatment >>

Multi-Functional Polyamine Single Shot Treatment - Accepta 2062 is a superior quality, multi-functional, polyamine based single shot product developed specifically for the treatment of steam boiler systems ... multi-functional polyamine >>

Multifunctional Treatment - Accepta 2088 is a very versatile, tannin based multi-functional water treatment product developed for use in boilers and closed circuit heating systems. Accepta 2088 also contains caustic for pH correction and carbonate for hardness control ... multifunctional treatment >>

Multifunctional Treatment - Accepta 2089 is a very versatile, combined tannin and carbonate based multi-functional water treatment product developed for use in boilers and closed circuit heating systems ... multifunctional treatment >>

Sulphamic Acid Descaler and Cleaner with Inhibitor - Accepta 2316 is a highly active cleaning agent and descaler based on sulphamic acid. Accepta 2316 is also supplied with a special film forming inhibitor to protect mild steel, stainless steel, copper and brass against acid attack ... sulphamic acid descaler plus cleaner and inhibitor >>

Hydrochloric Acid Descaler with Film Forming Inhibitor - Accepta 2317 is a highly active cleaning agent and descaler based on hydrochloric acid. Accepta 2317 also includes a special film forming inhibitor to protect carbon steel, copper and brass against acid attack ... hydrochloric acid descaler with film forming inhibitor >>

Scale Dispersant/Sludge Conditioner for Steam Boilers and Cooling Systems - Accepta 2318 is a superior water treatment product comprising a specially blended mixture of polymeric sludge conditioners developed for use in steam boilers and cooling water systems ... scale dispersant/sludge conditioner >>

Tannin Based Scale/Corrosion Inhibitor for Steam Boilers and LPHW Systems - Accepta 2319 is a superior, blended liquid water treatment product based on organic tannins, polymer sludge, conditioners and alkali. Developed for steam boilers and LPHW systems ... tannin based scale/corrosion inhibitor >>

Tannin Based Scale/Corrosion Inhibitor for Steam Boiler Systems - Accepta 2320 is an excellent, blended liquid treatment for the control of scale and corrosion in steam boiler systems. Accepta 2320 is based on organic tannin, polymer sludge conditioners and alkali ... tannin based scale/corrosion inhibitor >>
