    Disadvantages of hard water in industries Sugar industry: If nitrates, sulphates of calcium and magnesium are present, they cause hindrance to crystallization of sugar Concrete making: Water containing chlorides and sulphates, if used for concrete making, affects the hydration of the cement and the final strength of the hardened concrete. In steam generation boilers: If the hard water is fed Learn More

  • Water Treatment Storage and Blowdown for Steam Boilers

    Hardness. Water is referred to as being either 'hard' or 'soft'. Hard water contains scale-forming impurities while soft water contains little or none. The difference can easily be recognised by the effect of water on soap. Much more soap is required to make a lather with hard water than with soft water.Learn More

    Feed-water purity requirements therefore can vary widely. A low-pressure fire-tube boiler can usually tolerate high feed-water hardness with proper treatment while virtually all impurities must be removed from water used in some modern, high-pressure boilers. Only relatively wide ranges can be given as to maximum levels of alkalis, salt, silica Learn More

  • Boiler Feedwater Treatment (Part I): Why Water Treatment

    As the temperature increases, the solubility of oxygen decreases, but water under pressure can hold higher amounts of dissolved oxygen. Nitrogen, being inert, has little effect on water used in boilers. Water can contain 10 ppm of carbon dioxide, sometimes much more than …Learn More

  • Foaming and priming in boilers - Lenntech

    Boiler water carry-over is the contamination of the steam with boiler-water solids. Bubbles or froth actually build up on the surface of the boiler water and pass out with the steam. This is called foaming and it is caused by high concentration of any solids in the boiler water. It is generally believed, however, that specific substances such as alkalis, oils, fats, greases, certain types of Learn More

  • Hardness of Water - Types, Remove Temporary and Permanent

    The hardness of water is harmful to the boilers as the deposition of salts occurs, which reduces the efficiency of the boiler. Hard water is safe to drink but using over a long interval of time can lead to many problems like: Strains in skin; Water appliances work harder resulting in higher water bills; Spots appear on clothes and linensLearn More

  • pH Treatment |

    Alkalinity is a measure of the bicarbonate (HCO3), carbonate (CO3) and hydroxyl (OH) ions in the water. pH and alkalinity ratings are NOT the same and are NOT proportional. pH is rated on the Scale and alkalinity is measured in parts per million (ppm). A typically recommended alkalinity rating is 140 – 700 ppm for boilers operating below 300 psi.Learn More

    precipitator. The quantity of combustion gas produced in the boiler depends on the composition and amount of coal burned, the excess air used for combustion and the air in-leakage through the furnace, flues and air-preheaters. The volume flow rate through the precipitator is also a function of gas temperature and pressure.Learn More

  • Water Maintenance Essential to Prevent Boiler Scaling

    When untreated boiler water is heated, this calcium and magnesium will precipitate from the solution to form hard scale on the tube surfaces. In addition to the overheating and eventual failure of the boiler tubes due to scale, efficiency is also decreased in the short-term because of the scale's insulating effect on the heat transfer surfaces.Learn More

  • The Importance of Boiler Water and Steam Chemistry
