The main reason for the occurrence of blast furnace tube blasting in general industrial boilers is caused by poor or no water supply treatment at the water supply, causing scaling or corrosion. Pot fouling is due to the fact that the hardness of the feed water exceeds the specified standard for a long period of time, deposits scale on the inner wall of the furnace tube, and even blocks the furnace tube. Corrosion is caused by the oxygen content or acid value of the feed water exceeding the allowable regulations. According to investigations, many units have taken warning from the fact that they did not attach importance to the treatment of water supply, resulting in serious accidents such as the blasting of furnace tubes or the blocking of furnace tubes and the scrapping of boilers. Therefore, only by strengthening the management of water treatment can we fundamentally eliminate blasting accidents in furnace tubes, and we can also save a lot of fuel, steel, manpower and financial resources.
