The Role of Heat Storage Balls in Blast Furnace Smelting

2023-06-05 10:19:10

Heat storage balls, also known as spherical heat storage bodies, have the advantages of good thermal shock stability, large heat storage, high strength, easy cleaning, and reusability. In order to improve the utilization rate of heat energy and reduce energy consumption, heat storage balls are often used in blast furnaces as waste heat recovery. Through the double preheating of gas and air, the regenerative heating furnace can reduce exhaust gas by 20%-50%, reduce the exhaust gas temperature to below 150 degrees, increase production by 15%-20%, shorten billet heating time by 50%, and reduce oxidation burning. Lose 30%-50% of the environmental protection and energy-saving effect.

The heat storage ball is suitable for the selection of the heat storage ball combustion system of gas and non-gas fuel industrial furnaces, especially suitable for the heat storage furnace in the iron and steel industry, the heat storage ladle oven, the air separation equipment regenerator in the air separation industry, and the nonferrous metals. In regenerative smelting furnaces in the metal industry, heat storage balls can also be used as heat storage carriers in large-scale forging plants such as regenerative trolley furnaces, regenerative electric boilers, and regenerative incinerators.

In addition, it is especially suitable for regenerators of air separation equipment in iron and steel plants and blast furnace gas heating furnaces as regenerative fillers. The heat storage ball is double-preheated by gas and air, and the combustion temperature can quickly meet the requirements of steel rolling for billet heating.
