♦️Treatments for Moderately Rated Auxiliary Boiler: [Medium and Low Pressure Boilers] 🔘(1) Phosphate Treatment: 1. AGK 100 or Adjunct B is used. 2. Combat scale-forming salts to form non-adherent sludge. 3. Give Alkalinity to reduce corrosion. 4. Form Iron Phosphate Film on internal surfaces, as protection against corrosion. 🔘(2) Caustic Soda Treatment: [NaOH] 1. Maintain correct pH value and required Alkalinity. 2. Precipitate scale-forming Permanent Hardness Salts. [Chlorides and Sulphates of Calcium and Magnesium: They are in Acid nature. ] 3. Remove Temporary Hardness Salts. [Bicarbonates of Calcium and Magnesium: They are slightly in Alkaline nature.] 4. Excess concentration of NaOH may cause Caustic Cracking of metal. 🔘(3) Soda Ash Treatment: [Na₂CO₃] 1. Precipitate scale-forming Permanent Hardness Salts, (Non-Alkaline Hardness Salts) as Calcium Carbonate, CaCO₃. 2. Produce NaOH, to give required Alkalinity. 🔘(4) Dissolved Oxygen Treatment: 1. Two chemicals, Hydrazine N₂H₄, and Sodium Sulphite Na₂SO₃ are used to remove dissolve O₂. 🔘(5) Liquid Coagulant Treatment: 1. High molecular weight, colourless solution, likes Sodium Aluminate or Starch is used. 2. Coagulate oil droplets and Suspended Solids, and settle them at low points. 3.
