The charcoal pit lighter thing lets you mass-produce charcoal in "bulk", but its totally manual afaik. The best solutions for you are probably: a) Add more coke ovens, and b) Diversify your energy sources (look into gas/diesel) Also, if the railcraft liquid boiler is available (I dunno?) then it burns Creosote. if GT Large Boilers burn creosote. if you have the IC2 semifluid generator, it burns creosote (this one is often disabled in packs) Sorry my advice isn't pack specific. I took one look at the DOOR recipe and decided it wasn't for me.
