Getting the Design Right for a Reliable CO Mill Fire
Coal fires usually start in hotspots when coal absorbs oxygen from the air heat generated by this process can then ignite a fire. Without a complete combustion smouldering of fuel will produce large amounts of CO gas. The early detection of coal fires is essential to prevent catastrophic damage to expensive plant and serious injury to personnel.

Production normally takes place in a coke battery located near an integrated steel mill. In the battery coke ovens are stacked in rows. Coal is loaded into the ovens and then heated in the absence of oxygen up to temperatures around 1 100 degrees Celsius (2 000 degrees Fahrenheit). Without oxygen the coal does not burn it begins to melt.

BOF and EAF Steels What are the Differences Economics
The answer lies in capital costs. For a BOF firm the average cost per ton of capacity is 1 100 while the cost for an EAF minimill per ton of capacity is only 300. The barrier for entry is thus lower for EAF firms which can in part explain the rise of such "minimills" over the last half of the 20th century and into the 21st (WikiInvest).
