In vanilla minecraft Coal blocks have a higher BurnTime then 9 individual pieces of Coal combined (smelts 10 times 8 Items vs. 9 times 8 Items in a furnace). I think it wold be nice to have a similar bonus with blocks of Coal Coke.

Quote from Gamepedia: "One block of coal smelts 80 items, which is more than the smelting time of the 9 coal items used to craft it."

What is the fuel value of a Block of Coal?

I don't know the exact internal numbers, but a Block of Coal has 10 times the burn time compared to a single piece of coal.

Ps.: just noticed that that part of the original text got lost due to formating fails :(

Coal Block: 80 items=32000 fuel value
Coke Block: 144 items=57600 fuel value
(in vanilla furnace)
That will make Coke more useful in Bores or Steam Boilers.

The purpose is to change the fuel value of coke block to 64000.

And to change coke block into flammable block.

Yes, a Coke Block is better then a Coal Block. But according to my experience and mods.railcraft.common.plugins.forge.FuelPlugin the burntime of a Coke Block is equal to 9 pieces of Coke.

I hope its not 64000, because that massively overflows the Short used in the GUI burn progress packet.

I think you mean the Coke Block is 32,000 and Coal is 16,000.

Oh I thought wrong, 57600 is the value in 1.6, which can cook a steel with a coal coke. Since one version in series 8 the heat reduced, it should be 32000 now.

My pull request fixes the original issue. I didn't change anything regarding the suggestion from @liach: "change coke block into flammable block"

Edit:
A single piece of coalcoke has a fuel value of 3200; with this change the CokeBlock has a fuel value of 32000 instead of 28800. This means that a CokeBlock now smelts 2.5 stacks of items (=160) in a vanilla furnace.
