IE Blast furnaces won't accept Pyrotech coal coke.
(It would also be cool if there was some compat between coal tar/creosote oil but that's less important.)

You can use CraftTweaker to add valid fuels to the Blast Furnace:

//Example:
mods.immersiveengineering.BlastFurnace.addFuel(IIngredient input, int time);
mods.immersiveengineering.BlastFurnace.addFuel(<ore:plankWood>, 2000);

Which oredict do I need to add the Coal Coke to?

IE uses fuelCoke for the item, and blockFuelCoke for the block.

Thanks!

Looks like I already did this in 1.3.0:
