Now, when I put 1 wood log in campfire, BBQ, cursed cauldron, fireplace, the NightLantern works fine BUT the QuickSmelt seems not to work properly and the smelting time, the amount of resources it produces, the quantity of wood it takes look normal, as if the plugin is not loaded.

PLUS, if I put more than 1 wood log and then I pull away logs until 1 log left, then both the plugins stop working.

I will notify this to K1lly0u also. :-)

Thank you to the OP for saving lots of people literally hours of headache. As the kids used to say 'You da real MVP'.

1.) I know this is sort of Necro Sacrilege; but this is such a good post I wanted to contribute.  

2.) I still see a lot of questions pop up about this, so I thought I'd chime in. 

For those brand new to modding rust (or any unity game, really) you need to familiarize yourself with how XML works. You need to get in the habit of having a little scratch pad where you write your wants or ideas, and then you can go about building the config. It's really not hard once you figure out how mods work.

For instance, you may just want Ore to cook really fast, but not Foods. Or vice versa. Or you may want ONLY a specific appliance like an electric furnace to be like super duper fast..where everything else like primitives are SLOWER.. You can do all of this with the config file.

It is IMPERATIVE (that means really frickin important) that you know the item names, their corresponding outputs, etc. 
Our great friends over at lone.design has a pretty thorough list.
Lone Design Item Lists

This will help you navigate the above example with ease and tweak it to your specific desire.

Also, i can't stress enough, spin up a different instance of Rust Server with ONLY this mod in it, while you tweak. This way you can insure no other Mod is jacking with your results, before 'merging to main' or otherwise pushing it to your server with the rest of your mods.

Be young, have fun, drink pepsi. 

I'm getting ready to set one of these up for a 2x speed only. Output would remain the same, just smelt faster. So would I just change the 1.0's to 2.0's?

How to you make it produce charcoal faster? I used the above code and it produces smelted ore fast but barely any charcoal
