Why is coke used instead of coal?
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.
What is the difference between charcoal coal and coke?
Charcoal is a type of fuel made from the incomplete combustion of wood. Coke is a fuel made from mineral coal that has been calcined or dry distilled. It is carbon-based and has a high calorific value, but it is also quite polluting. Steel foundries utilise it as a fuel in their blast furnaces.
What advantage does coke have over coal as a fuel?

Why is coal called a fossil fuel?
Coal is called a fossil fuel because it was made from plants that were once alive! Since coal comes from plants, and plants get their energy from the sun, the energy in coal also came from the sun. The coal we use today took millions of years to form. … Heat and pressure turned the dead plants into coal.
