Basic Oxygen Furnace Gas Recovery and Cleaning System
During the process of steelmaking in the basic oxygen furnace (BOF), oxygen (O2) is blown in the charge mix and due to the chemical reactions taking place in the converter vessel, a large amount of gas at high temperature and rich in carbon mono oxide (CO) comes out through the mouth of the converter. At this stage, the gas is very hot ...

Boiler Performance and Mill Outlet Temperature
The mill outlet temperature of coal-air mixture is maintained between 65 to 90 degree centigrade in the case of low and medium volatile coal. In the case of high volatile coal, while the lower limit generally remains as 65 degree centigrade, the upper limit is restricted to a lower level depending on percentage of volatile content in coal.
