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



Chemtex Boiler Feed Water Chemicals

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

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...

How RO Antiscalant works?

  Reverse Osmosis technology provides an efficient and reliable method for purifying water for various purposes). It can remove impurities such as salts, minerals, and other contaminants as well as microbial contaminants from the Membrane. Water molecules pass through RO membranes despite dissolved solids and other contaminants being rejected by the membrane. RO membranes are basically thin, dense, and semi-permeable membranes. However, the major significant challenge in Reverse Osmosis System is Scaling. Why does it happen? The formation of scales on the RO (Reverse Osmosis) membrane is primarily caused by the presence of certain dissolved minerals and salts in feed water. Scale refers to the accumulation of mineral deposits, such as calcium carbonate, calcium sulphate, and silica which can severely impact the efficiency and the lifespan of the RO membrane. RO Membrane scaling may lead to cause ·          Excessive Energy Consumption...

Excellent Efficiency Flocculation with Polyelectrolyte

Polyelectrolytes are regarded as polymer chains with an electrolyte group on every repeat unit. When dissolved in a polar solvent, these polymers are charged due to dissociation of small counter ions that leave behind a charged macro ion. Polyelectrolytes include biologically important molecules such as polypeptides and DNA. These are referred to as polymers that are generally used for water purification. These are highly noted for their beneficiary nature of handling problems of slow settling of flocs in water at low temperature, treating soft colored water where they increase toughness of the flocs and enhance its settlement ability. Polyelectrolytes are formulated in a way so as to be used as coagulants and flocculants as well as a sludge dewatering agent in the waste water treatment plants. P olyelectrolyte , thereby, plays an indispensable part in the sludge conditioner formulation. Generally flocculation occurs owing to charges present on the particles. Generally, Pol...
