Description
Summary:A steam boiler is a closed vessel that produces steam used in many industrial fields. Steam boilers suffer from the pipe corrosion problem, which leads to damage and explosion of the steam boiler. Steam boiler tubes corrode due to the solid dissolved salts and pH of water. The total dissolved solid salts concentrate on the tube walls when the temperature rises, and as a result, scales are formed on the metal. The crusts formed on the wall of the pipes reduce the heat transfer from the pipes to the water, and thus the pipes’ temperature will rise, which leads to pipe damage. The pH also plays an important role in the corrosion of the pipes, as it was found that the pH decreases when the water temperature rises, and thus leads to pitting corrosion of the metal due to the acidic environment of the water. Therefore, chemicals must be used to control the pH, as well as convert suspended salts (TDS) into dissolved salts and dispose of them by the automatic detonation of the boiler water.
