Syn Water Technologies specialize in steam boiler water treatment. Syn water is a leading manufacturer and supplier of comprehensive range of boiler water treatment chemicals, dosing systems, and water softeners and offer high quality on-site technical service. When water is converted to steam it expands in volume into many times, thus subsequently steam moves the energy and heat where it is wanted, but without the right boiler feed water treatment, a steam-raising plant will suffer from scale formation and corrosion. Consequently it increases energy costs and can lead to downgrade steam, reduce productivity, shorter plant life. An inadequately treated boiler is a potential bomb and exposure to steam will cause severe burns and scalding and may accelerate more serious complexities at plant and operation.
In order to keep plant operating safely, efficiently and economically, Syn Water has developed a comprehensive range of products and technical services to protect boiler and the whole steam system including the feed-tank, feed-lines, steam and condensate system.
The persistence of Syn boiler water treatment is to render cost effective inhibition to the boiler and steam system against corrosion and scale formation and help to uphold steam pureness and desired quality.
Boiler scale is caused by the precipitation of insoluble salts of calcium and magnesium at high temperature. As a result, it produces a hard layer on the boiler tubes, which severely reduces the heat transfer, which is critically unwanted, thus it greatly reduces the efficiency of the boiler and instigates the boiler tubes to overheat, so that in an extreme situation they can rupture the tubes & lines with very risky consequences.
Formation of scale deposits is avoided initially by removing as much hardness from the make-up water as possible ( through water softener), and then by dosing Syn boiler water chemicals such as Scale preventive and polymer sludge conditioners viz; Syn-600, 601,602,603 range of chemicals. These Syn Boiler treatment chemicals ensure that any hardness Slipped-in boiler feed water is converted into a floating sludge, which can be removed by boiler blow down and so doesn’t form any hard scale on the heat transferring surface.
Similarly, Corrosion in low-pressure boilers can be affected by dissolved oxygen, acidity and excessive alkalinity. Syn Boiler Water treatment therefore should remove the dissolved oxygen and retains the boiler water with the appropriate pH and alkalinity levels. The oxygen content of water reduces with intensifying high temperature. it proves therefore that basically increasing the boiler feed water temperature, and allowing the oxygen plenty of chance to get-away, will suggestively decrease the threat of oxygen corrosion at boiler system. A correctly designed feed water container is consequently the primary protection in protecting the boiler from oxygen corrosion. The feed water tank temperature should be maintained at a minimum of 80°C. This could be attained by recollecting as much as hot condensate is possible and by steam injection at feed water tank. A feed temperature of 85–90°C is accepted, but the plant should evade increasing the temperature too high, since it will support other damage in the metallurgy of feed pump.
In order to remove the remaining oxygen from the feed water, a Syn chemical oxygen scavenger, such as Syn-607 Sulphite based / Hydrazine based / Carbo-Hydrazine based is added in direct proportion to the amount of remaining oxygen.
Further, dry steam does not tend to corrosion, but once the steam condenses again to form water, it can attract & absorb the corrosive gases, oxygen and carbon dioxide, which if not adequately treated, can promote to rapid failure of condensate return lines due to low pH and and dissolved oxygen. Corrosion due to Oxygen or low pH, which leads to pitting on the condensate line, can usually be prevented by implementing an effective Syn oxygen scavenger viz; Syn-607 and Syn-607 (1) to the boiler feed water or by the addition of special steam volatile chemicals such as neutralizing and filming amines namely as Syn-608, Syn-609. Depending on their nature, these chemicals can either be dosed into the boiler feed water or injected directly into the steam header.
