Boiler Water Treatment in Bangladesh

Boiler Water Treatment – Boilers in industries generate steam which in turn is used to generate power and heat thus boiler is a device for generating steam it consists of two main parts furnaces and boiler proper furnace provides heat by burning the fuel and the boiler proper is a device where water changes into steam due to heat this steam or hot fluid is then recirculated out of the boiler to be used in various process in heating applications, the water which is fed into the boiler is called boiler feedwater these days modern boilers required high-quality water to operate efficiently such water can never be obtained from any the natural sources.

What Is Boiler Water Treatment?

Boiler water treatment is a process of purifying and perfecting the quality of the water that’s used by a boiler system. The combustion process within a boiler relies heavily on the clarity and quality of the water so that it can perform the tasks that it was created for producing high-quality brume, guarding against erosion, and performing nonstop heat exchange. When the water that a boiler uses isn’t treated, the entire system can suffer from poor effectiveness and endless damage to an outfit that shortens the boiler’s life and may also produce a dangerous situation where they could explode due to superheating.

Why Boiler Water Treatment Is Important

Boiler water treatment is critical to ensure that the ministry functions duly for as long as possible. When contaminations live in the boiler water, they can foul the system and produce lasting damage that will dock the life of the outfit and reduce its efficacity, which translates to advanced bills for the same performance. Dissolved mariners in the water produce scaling, and other pollutants and products within the water will attack the ministry if not removed by external or internal boiler treatment.

An HVAC water treatment specialist that’s working on a marketable boiler water treatment is critical to ensure that the ministry functions duly for as long as possible. When contaminations live in the boiler water, they can foul the system and produce lasting damage that will dock the life of the outfit and reduce its efficacity, which translates to advanced bills for the same performance. Dissolved mariners in the water produce scaling, and other pollutants and products within the water will attack the ministry if not removed by external or internal boiler treatment.

Reduce Putrefying Of Boiler Tubes

The dissolved mariners in water will collect on shells when the water is faded as part of the boiler’s regular function. These mariners block some of the transfer of heat from the boiler, which reduces the overall effectiveness and effectiveness of the system. In addition, any boiler tubes that fill with scaling will constrict as a result, reducing inflow and contributing to press drops. Tubes that are full of scaling will need to be replaced, which costs both time and plutocrat.


In addition, if a boiler is using water with low pH or dissolved oxygen, the water will directly attack any sword outfit that makes up the boiler. Over time, this will affect recesses or indeed holes and thinning forming in the boiler tubes, which may beget them to rupture and compromise the entire system.

Steam boiler Water Treatment Solutions

Depending on the operation, boiler type, and make-up water conditions, colorful-treatment systems will be necessary to help with scaling and other implicit issues in the system. Pre-treatment could include but isn’t limited to filtration, water softening, Rear Osmosis, and mixed-bed resin. Each system is different and has unique demand for effective-treatment and careful attention must be paid to the system in order to help to scale, reduce water and chemical operation, and conserve energy.

Pre-treatment Boiler Water

Beyond an effective-treatment system, chemical treatment is frequently used as a final step in the water exertion. To help to scale, colorful products are used that may modify the chargers, disperse the chargers, increase the threshold at which they form, or indeed reply to form undoable effects that will come out in the blowdown. Dissolved oxygen in a boiler is one medium that can beget erosion in the system. An oxygen scavenger is used to reply with any trace oxygen in the boiler water treatment to help implicit bending erosion.

Numerous operations will have some chance of condensate return in order to save energy and reduce boiler water operation by reusing the pure, heated water. As the brume condenses, carbon dioxide has a tendency to form carbonic acid which lowers the pH of the boiler water and can beget erosion on the return line. One way to address this is through the use of negativing amines to neutralize the acid and maintain a proper pH, therefore guarding the metallurgy of the system.

Beyond the chemistry briefly mentioned over, there are numerous other products that are gaining instigation in the request. From Film Forming Amines( Polyamines) to purified tannins there are numerous products that may give superior boiler water treatment results in specific operations.

Solution for industrial boiler water treatment

To sustain high-chastity feedwater and make-up water inflow, an optimum boiler water treatment system primarily consists of pressure sludge, softening factory, a reverse osmosis unit, and a thermal deaerator.

The use of common hard mains water as make-up water for a brume boiler will beget rush of a lime gravestone on the boiler heat area. therefore, increasing the energy loss and the quantum of acid for drawing the boiler outside.


By softening the water, scaling is averted but the content of bicarbonate in the raw water passes the softening factory without interference. In the boiler, the bicarbonate splits into carbon dioxide( CO2) and sodium hydroxide( NaOH) creating sharp condensate and increasing the need for blowdown. The problem can be avoided by removing the swab content of the make-up water in a reverse osmosis factory or in a two-column ion-exchange factory to get demineralized water and also degassing with a thermal deaerator.

Boiler water treatment is a type of artificial water treatment concentrated on the junking or boiler chemical revision of substances potentially damaging to the boiler. Varying types of treatment are used at different locales to avoid scale, erosion, or raging. External treatment of raw water inventories intended for use within a boiler is concentrated on the junking of contaminations before they reach the boiler.

Boiler water treatment chemicals


Internal treatment within the boiler is concentrated on limiting the tendency of water
to dissolve the boiler and maintain contaminations in forms least likely to beget trouble
before they can be removed from the boiler in the boiler blowdown.

Oxygen scavengers

Sodium sulfite or hydrazine may be used to maintain reducing conditions within the boiler. Sulfite is less desirable in boilers operating at pressures above pounds per forecourt inch( kPa); because sulfates formed by combination with oxygen may form sulfate scale or putrefy into sharp sulfur dioxide or hydrogen sulfide at elevated temperatures. redundant hydrazine may dematerialize with brume to give erosion protection by negativing carbon dioxide in the brume condensate system, but it may also putrefy into ammonia which will attack bobby blends. Products grounded on rephotographing amines similar to Helamin may be preferred for erosion protection of condensate systems with bobby blends.

Coagulation

Boilers operating at pressures lower than 200 pounds per forecourt inch( kPa) may use unsoftened feedwater with the addition of sodium carbonate or sodium hydroxide to maintain alkaline conditions to precipitate calcium carbonate, magnesium hydroxide, and magnesium silicate. Hard water treated this way causes fairly high attention to suspended solid patches within the boiler to serve as rush capitals precluding latterly deposit of calcium sulfate scale.

Natural organic accouterments like beans, tannins, and lignins may be added to control crystal clear growth and disperse precipitates. The soft sludge of effects and organic accouterments accumulates in inert portions of the boiler to be removed during the nethermost blowdown.

Phosphates

Boiler sludge attention created by coagulation treatment may be avoided by sodium phosphate treatment when the water hardness is lower than 60 mg/L. With acceptable alkalinity, the addition of sodium phosphate produces an undoable precipitate of hydroxyapatite with magnesium hydroxide and magnesium and calcium silicates.

Lignin may be reused for high-temperature stability to control calcium phosphate scale and glamorous iron oxide deposits. respectable phosphate attention drops from 140 mg/ L in low-pressure boilers to lower than 40 mg/ L at pressures above pounds per forecourt inch( kPa). Recommended alkalinity also decreases from 700 mg/ L to 200 mg/ L over the same pressure range. raging problems are more common with high alkalinity.

Coordinated control of pH and phosphates attempts to limit acidulous erosion from the attention of hydroxyl ions under the previous scale on brume generating shells within the boiler. High-pressure boilers using demineralized water are most vulnerable to acidulous erosion.

Sulfite/Sulfite

Our product range includes chemical oxygen scavengers based on sodium sulfite or sulfite which is fast-acting, easy to test for, and ideal for low-pressure boiler applications.

Reduce Overheating

When impure water is converted to brume, its contaminations are transferred across all of the shells of the boiler system. This generates scale and other deposits, through which the boiler’s normal heat doesn’t pass as effectively. Because the heat must access the subcaste of deposits before it can be transferred out of the boiler, systems that haven’t experienced water treatment tend to witness an increase in overheating. Using purified water in boilers ensures that no deposits or spanning form so that the boiler can continue with its regular heat exchange demonstrative.

Minimize boiler blowdown and save water and energy

Blowdown of brume boilers is necessary to misbehave with the specifications of the boiler suppliers as to the contents of the swab( specific graveness) and the alkalinity( P-value) in the boiler water. The volume of blowdown is determined by the boiler type, operating pressure, and water treatment quality of feed and makeup water.

In high-quality boiler water, situations of suspended and total dissolved solids( TDS) are down to a minimum. This will minimize blowdown volume and hereby reduce energy loss, as the temperature of the blowdown liquid is the same as the brume generated in the boiler. A lower blowdown rate will also reduce makeup water and chemical use, saving you plutocrat and water.
