Boiler Feed Water Chemicals

 

The main types of industries that use boilers include the pharmaceutical, textile, steel, and chemical industries. The performance of any boiler system depends on the efficiency of heat transfer, from the fireside to the waterside. In the continuous operation, scales or deposits develop on the boiler tubes which affect the heat transfer taking place in the boiler. Chemical treatment of boiler feed water for treatment and conditioning of feed water maintains optimal heat exchange, and protection of the boilers.

Boiler feed water chemistry

Porous forms of salts such as Calcium, Magnesium and high carbonaceous deposits precipitate and form dense uniform pitting and scaling over the boiler surfaces. With the feedwater, the dissolved solids and impurities begin to precipitate at the base, with a continuous accumulation.

Along with dissolved salts, there are also some suspended solids in that get precipitated as sludge. These are not hard as compared to scales, but if overlooked, gets hardened due to continuous heating in the boiler.

Boiler feed water characteristics – Scales

•         Carbonate deposits, granular and porous form dense and uniform pitting and scaling

•         Sulphate deposits, crystalline fine particles harder and denser than regular carbonate deposits

•         Hard and difficult to remove silica deposits, extremely small, forms a dense and impervious scaling

•         Iron (Fe) deposits

Effects of scaling in boiler operations

·         Brings down boiler efficiency as the scales act as a heat insulator, not allowing the optimum heat transfer, causing the boiler tube to overheat and fail.

·         Plugging / irregular deterrence

·         In general, boiler deposits can cut operating efficiency,

·         Unscheduled boiler shutdowns

·         Increases in damage and repair cost, at times even leading to replacement

Boiler water treatment and conditioning of boiler feed water to maintain optimal heat exchange, and protection of the boilers. If you want your boiler to remain in good condition and be as efficient as possible, it’s important that the water remains free from impurities, which means that water treatment will be necessary.

There are two methods that can be used for the chemical treatment of boiler feed water, which include external treatment and internal treatment.

Both of these processes rely on the conditioning process, which essentially counteracts the hardness in water by introducing softening agents to the water. Once these agents have been placed in the water, most of the minerals, contaminants, and chemicals within the water should be altered or removed completely.

Chemtex Speciality Limited has over five decades of experience in manufacturing boiler chemicals and consultation. With a wide portfolio to choose from to effectively counter or prevent mineral scales, metal oxides, hard deposits of water scale, iron oxides, oily contaminants, sludge, lime, and greasy deposits on the boiler surfaces.

Using these chemicals regularly ensures the protection of the system metallurgy, providing a long service life for the boiler system. We formulate a range of boiler chemicals to ensure the safety of the boiler and feed water. This formulation eliminates mineral scales, metal oxides, sludge, and other depositions, prevents corrosion caused by oxidation, maintains pH values, and removed oxygen instantly.

Key Features & Benefits

·         Excellent efficiency of removal scales, sludge, and other depositions

·         Non-corrosive & cost effective

·         Leaves no hazardous residue on the surfaces

·         Enhance operational efficiency and prevents system shut-down

RO Antiscalant

Reverse Osmosis serves as one of the most critical processes that are involved in the process water treatment to clean water, utilized in various industrial process applications. Reverse Osmosis can be regarded as the process wherein semi-permeable membranes help in separating purified water from contaminated water. It occurs when a pressure is applied to the concentrated side of the membrane resulting in forcing purified water to the dilute side. Reverse Osmosis is very efficient for the treatment of brackish, surface and ground water for both large and small flow applications. Some examples of industries that use RO water include boiler feed water, food and beverage, pharmaceutical, metal finishing and semiconductor manufacturing to mention a few. The overall performance of a reverse osmosis system relies on various factors like feed water quality, membrane type, flow control, temperature and pressure. Systems must be well maintained for ensuring effective performance with any

Hybrid Organic Acid Technology (HOAT) Coolant

Optimal use of machines is directly proportional to its engine performance. What an engine does is it converts the supplied energy into its mechanical form, driving the machine to work. Engines require one-third of total heat that is generated during conversion and the rest of the heat is needed to be evacuated from the combustion chamber which would otherwise lead to engine failure. Earlier, water was preferred as an ideal coolant for quite a period of time but the problem started to arise when the temperature would become extremely high or low, to be precise temperature more than 100 ° C and below 0°C. To get rid of this problem, coolants were formulated. Coolants are categorized chemicals that increases the boiling point of the fluid and decreases the freezing point of the fluid to make it suitable for use in extreme heat and freezing conditions. Coolants are a proportionate mixture of antifreeze and solvent, mainly glycol and water. Ideally utilized as a preventive in

Antiscalant Chemical for RO Plant

  Reverse Osmosis System is a revolutionary invention to treat water and provide an effective solution for purifying water in various applications. The performance of RO can be ensured by the formation of scale and deposits on the membranes, leading to reduced efficiency and increased operational costs.   To prevent this issue, antiscalant chemicals play an important role in reducing the formation of scale and maintaining optimal RO Plant performance. Reverse Osmosis is widely used in various industries to treat water and to remove impurities such as salts, minerals, and other contaminants. The dense, thin, and semi-permeable layer allows water molecules to pass through while rejecting dissolved solids, and other impurities such as salts, minerals, and other contaminants. But the major issue that surfaces in such systems is the formation of scales due to the build-up of dissolved minerals and salts on the surface of the RO Membrane.
