How is the scale formed in the فرن التدفئة التعريفي?

Generally, cooling water contains calcium ions and magnesium ions, as well as bicarbonate ions. The thermal decomposition temperature of calcium bicarbonate and magnesium bicarbonate is lower than 100 degrees Celsius. Calcium bicarbonate will decompose into calcium carbonate, carbon dioxide and water. Magnesium bicarbonate also Decomposes into magnesium carbonate, carbon dioxide and water. When boiled for a long time, magnesium carbonate will react with water and partially or fully convert into magnesium hydroxide. Because magnesium hydroxide is less soluble than magnesium carbonate, continuous heating produces more insoluble magnesium hydroxide. Calcium carbonate, magnesium carbonate, and magnesium hydroxide are all substances with low solubility, which will precipitate out of water to form precipitation crystals. Therefore, the main components of scale are calcium carbonate, magnesium carbonate and magnesium hydroxide, and may also contain a certain amount of magnesium bicarbonate. Scale is mainly formed on the cooling inner wall of the electrical components of the induction heating furnace, the inner wall of the transformer cooling copper tube, and the inner wall of the inductor copper tube. power reduction.
