Pollution Effects of Abnormal Operations in Iron and Steel
The heated air becomes the hot blast for the furnace. This use of refractories for absorbing and retransmitting heat is termed regenerative heating. It provides thermal efficiency for the furnace and at the same time accelerates the reactions within the furnace. On modern furnaces the temperature of the hot blast may exceed 1093°C (2000°F). 11
