(In response to article about fuel efficiency in blast furace.)

You can use coal coke in a regular furnace, and it converts 32 units per piece of coal coke. So it would be best to convert one piece of coal into coke, then use that coke to convert wood to charcoal. This way you still get some creosote as well.
