This tutorial teaches you how to make a custom fuel. The requirement is that you already have an item made. If you don't know how to make an item, you can see my other tutorial. This is a basic tutorial, and is very simple, assuming you already have an item you want to use. This can also be applied for making an item already in Minecraft smeltable.
The first thing you want to do is, on the main page, click "New Mod". This will open a subwindow. Type in the name of the fuel, for simplicity reasons, and select fuel. Click Ok.
A new window will pop up, with the furnace GUI. In the place where you would normally place coal, or any other smeltable material, click. A new subindow will pop up. Just scroll around until you find the item you want to smelt stuff. If it is a custom item, it will be somewhere around the far right. Once you have an item selected, click OK and the subwindow will drop. At the top of the window, you will notice the "Power of fuel". This defines how fast an item will smelt. 1,600 is how fast a regular coal will burn, so use that to gauge. Click Finish.
You will find a new window. Simply skip it. You will be brought back to the main window after clicking finish again. Wait for the mod to compile, then test it!
