Learn MoreAs can be seen from this Table, the sequestrants tested include not only well-known complexing agents such as EDTA and NTA but also polymeric sequestrants, as well as other sequestrants. As will be shown later, only those sequestrants which have chelation values above 200 can be shown to function as effective transport agents in a boiler system.

Learn More2020-12-30 · Boiler corrosion is the active destruction of sound boiler metal by the pitting action of dissolved oxygen in the boiler water. This usually results in deep holes in the metal which are self protected by further corrosion products ie scabs or blisters over the hole which allow the chemical reaction to continue.
Learn MoreThe enhancements to EN 12953 Parts 2 and 3 ensure that only materials with the correct metallurgical properties and notch toughness are employed in boiler designs. In the case of boiler furnaces, which are exposed to high heat fluxes, the improper use of high strength fine grain materials without the prerequisite notch resistance could lead to

Learn MoreIf hydrazine (N 2 H 4) is not used, sodium sulphate (Na 2 SO 4) can be used instead, and the excess should be 30 – 60 ppm.. In cases where other kinds of oxygen binding agents are used, it is recommended that an excess of oxygen binding agents can be measured and indicates that no oxygen has been dissolved in the boiler water.
Learn More2 · The fate of the ferrous ion (Fe2+) depends on condensate temperature, pH, and flow conditions. At low temperatures, Fe 2+ reacts with water to form insoluble ferrous hydroxide, Fe(OH) 2.If the condensate stream velocity is high enough, colloidal Fe(OH) 2 is swept into the water and car-ried downstream to deposit elsewhere. In low-flow areas of the condensate system, Fe(OH) 2 deposits
Learn MoreThe treatment and conditioning of boiler feed water must satisfy three main objectives:. Continuous heat exchange; Corrosion protection; Production of high quality steam; External treatment is the reduction or removal of impurities from water outside the boiler. In general, external treatment is used when the amount of one or more of the feed water impurities is too high to be tolerated by the
