Butibori Power Plant - Wikipedia

The coal is initially about 300 mm in size. It is crushed to 20 mm and then put into a coal mill, which pulverizes it into extremely fine powder of around 70 microns. The powdered coal is then supplied to the top of the boilers via tubes and primary air (PA) fans, where it is burnt to generate heat and convert the water in the boilers to steam.

How a Coke Plant Works - GASP

How a Coke Plant Works. Coal is the main ingredient used to make coke. Iron is produced by inputting coal into a blast furnace. However, coal cannot be put directly into a blast furnace because of all the harmful by-products that come from that. So, there is an intermediate process that occurs. Coal is converted into coke first.
