The result is coke, a fuel that is almost entirely carbon allowing us to reach temperature of 3,000 to 4,000 degrees Fahrenheit at the core of the fire!
How hot is an ember?
The results show that the temperature of the glowing embers increases with increasing air flow. The measured mean glowing temperatures ranged from (750^circ mathrm{C}) at 1 m/s to (950^circ mathrm{C}) at 4 m/s. A glowing combustion model explains the dependence of the temperature on the air speed.

The industrial production of coke from coal is called coking. The coal is baked in an airless kiln, a "coke furnace" or "coking oven", at temperatures as high as 2,000 °C (3,600 °F) but usually around 1,000–1,100 °C (1,800–2,000 °F).
Why do we use coke not coal for making iron?
The single most important factor is strength ( mechanical compressive ); coal is heated to make coke, the resulting coke is stronger than the original coal. Also, coke helps to make the charge of iron oxides and limestone more porous to permit gas flow up and droplets of liquid iron and slag down.
