Behavior of three non-coking coals from Iranian''s deposits ...

Abstract The behavior of three types of non-coking coals from Iranian''s deposits in thermal regime of tunnel kiln direct reduction of the iron (TKDRI) process has been investigated. The heating condition of raw materials in tunnel kiln was simulated in a vertical TGA for three different non-coking coals. For non-isothermal devolatilization of coals from room temperature to 1100 °C, the ...
