What is boiler water treatment?

Boiler water treatment is the conditioning and treatment of boiler feed water for the three purposes of continuous warmth trade, quality steam protection and corrosion safety. Boilers are designed to warmth fluids, and then the evaporated or heated fluid will leave the boiler and be used for heating applications and various industrial processes, similar to sanitation and cooking. Some of the major industries that use boilers are pharmaceutical, textile, metal and chemical industries.
If you want your boiler to stay in good situation and as environment friendly as possible, it is necessary that the water remains free of impurities, which signifies that water treatment is critical. There are two strategies of treating boiler water, an exterior therapy and an inner remedy. Both processes rely on a conditioning course of that essentially counteracts the hardness within the water by introducing softeners into the water. Once these agents are placed in the water, most of the minerals, contaminants and chemicals in the water must be fully altered or removed. Whichever of these strategies you use, there are numerous efficient chemical compounds that can be used to maintain the water freed from impurities, together with every thing from de-oxidizers to anti-scalers.
Boiler therapy chemical compounds

A guide to some of the extra frequent chemicals utilized in boiler water remedy is offered under.
Oxygen scavenger

Oxygen scavengers are specifically designed to cut back the amount of dissolved oxygen and oxides in water. If you use a DO sensor and find excessive levels of dissolved oxygen in your boiler water, deaerators similar to hydrazine and sodium sulfite can successfully cut back DO and oxides, leading to purer water. Deaerators also usually passivate numerous metallic surfaces, which helps forestall rusting and different issues.
When you introduce chemical deaerators into boiler water, it is feasible for you to to remove any residual oxygen from the feedwater, protecting the boiler from harmful chemical reactions and reducing corrosion within the feedwater tank and return line. Tannin chemical compounds and sulfite chemicals have been shown to be particularly effective deaerators. If you determine to make use of sodium sulfite, this deaerator will work quickly and is very appropriate for low strain functions. As for tannins, this chemical will remove oxygen from the water and also form a corrosion-resistant movie across the boiler metal.
The actual dose of deaerator you need to use in your boiler depends on the kind of deaerator you employ and whether the boiler is paired with a de-gas heater. For testing purposes, you should all the time keep 20 ppm of deaerator within the boiler feedwater. If you want to be certain that your boiler doesn’t corrode, it is highly really helpful that you use a deaerator.
Alkalinity generator

Alkalinity turbines are particularly designed to boost the pH of the water by which they’re applied. For steam boilers, you will want to maintain a excessive pH to forestall corrosion, reduce the amount of silica plating in high-pressure boilers, and keep correct boiler efficiency. If your feed water has a high alkalinity, an alkalinity booster isn’t always needed, but when the water in your boiler turns into too acidic, you must think about using an alkalinity booster.
All you need to do to determine the pH of the boiler water is to check it with a pH sensor. If the pH drops too far, an alkalinity builder will assist you to increase the alkalinity of the water. When you improve the alkalinity of the boiler feed water, it is feasible for you to to guard the feed traces and scorching wells from acid corrosion. The quantity of this chemical you want all depends on how low the pH of the feedwater is.
The commonest alkaline options for boiler water embody sodium hydroxide and potassium hydroxide. You can normally buy these merchandise in concentrations of 25% or 50%. If you should considerably improve the alkalinity of your feed water, a 50% resolution could additionally be your best choice. Some alkalinity detergents include sludge conditioning polymers, which could be notably beneficial for top temperature applications.
Amines

Amines are neutralizing chemical compounds that stop corrosion of condensate tubes on boilers. Condensate from steam boilers could be highly corrosive to the tubes, which might harm your boiler and trigger you to make costly repairs to repair the issue. The three neutralizing amines you presumably can acquire for boiler water treatment purposes embrace morpholine, diethylaminoethanol and cyclohexylamine. While these neutralizing amines could be bought as a single element, most solutions will be combined with these three components.
When these amines are placed in boiler water, they enhance the pH of the condensate, which significantly reduces the potential for corrosion. It is well known that low pH in condensate piping can result in important corrosion, which can result in condensate leaks and steam leaks. Once this chemical is applied to the water in your boiler, you’ll achieve higher boiler reliability, cleanliness and protection. While condensate piping is the primary space of concern, this chemical will shield all condensate methods. To determine if this chemical is needed, it is strongly recommended that you take a look at the return condensate with a pH sensor.
Scale Inhibitors

Scale inhibitors are used to reinforce the dispersion properties of any conditioning product used in boiler water. Scale inhibitors typically encompass a mixture of polymers and phosphates. These antiscalants can be used as man-made or natural chemical compounds. The most common natural polymers embrace tannins and lignin sulfonates, while synthetic polymers out there in your use embody polystyrene sulfonates and maleic acid ester copolymers.
These chemical compounds act as softeners to reduce scale buildup within the boiler. Scaling can be a main downside for boilers as a outcome of it causes a big reduction in boiler efficiency. When harder impurities similar to magnesium salts and calcium start to increase in boiler water, they eventually become concentrated, which suggests they will adhere to the pipes and different surfaces of the boiler.
The commonest feedwater contaminants that may result in scale formation embody magnesium, aluminum, calcium, iron and silica. If you don’t get rid of scale quickly, it’s going to first scale back the efficiency of your boiler. Eventually, the affected tubes could rupture or overheat. Solenoid dosing pumps are normally used to add scale inhibitors. Mechanical diaphragm metering pumps are more appropriate for big flow of chemicals. The amount of scale inhibitor you utilize in your boiler water depends on the hardness of the water and the amount of scale that varieties. It is recommended that you simply use a hardness check equipment to find out the effectiveness of those antiscalants when treating water with them.
External and inside treatment of boiler water

The treatment of boiler water is divided into two sorts: exterior remedy and inner remedy. With exterior therapy, once the water is removed from the boiler, impurities are reduced or completely faraway from the water. If the extent of impurities in the feed water is very high, it might damage the boiler and it is suggested that you just use the external treatment methodology. After eradicating the feed water, it will be purified and degassed. It may additionally be pretreated by evaporation, which produces some pure steam that might be condensed and used within the treatment course of. This therapy method softens the water, reduces silica and alkalinity, removes suspended matter and reduces oxygen. However, this course of could be time consuming and is often unnecessary.
As for the interior treatment of boiler water, this course of requires conditioning of impurities within the water, which means that the water is softened with softening chemical compounds similar to sodium phosphate and soda ash. The main purpose of internal therapy is to correctly scale back hardness, sludge and take away oxygen from the feed water. The solely step concerned in the internal therapy course of is to determine which kind of softener you wish to use. If you should reduce scale buildup, the softeners you introduce into the boiler water will react with the magnesium and calcium compounds already current in the water. With the proper combination, unwanted impurities should be softened and dissolved.
If your primary objective is to control sludge, you can use dispersion or coagulation. If the sludge stage in the feedwater is excessive, coagulation can help by forming giant particles that can be easily eliminated. If the sludge is at a relatively low stage, dispersion breaks up the sludge and disperses it through the boiler water. In most circumstances, internal treatment ought to be all you have to deal with the boiler water.
