Ever heard of a Larry car?

used in the process of heating up coal to make coke.

What makes coking coal distinct is that it is a fuel with few impurities. Most grades of coke are from 86 to 93 percent pure carbon and produce a clean intense heat when burned. Coke is made by heating coal in a controlled atmosphere, driving off most of the impurities, and leaving a porous structure strong enough to support the iron ore that coke is often used to heat.
