Describe the bug
Make sure to include:

1. What did you expect to happen?
   when a forge is out of fuel bellows would not allow it to gain heat without re-lighting with more fuel.

2. What actually happened instead (i.e. what was the bug)
   If the forge does not cool down completely you can keep the forge going at least at lower temperatures sufficient to melt metals like bismuth and zinc or cook food. So long as the forge does not cool down completely this effect is indefinite it would seem. I have not looked into you your code but it feels like the bellows is updating the forge thinking it is still lit because there is some temperature to it and not checking if there is actually fuel for it to use to do so, sorry if that last bit was unwelcome.

3. If it was a crash, upload the full log file (latest.log)
   no crash occurs

4. If they would help to explain the issue, include screenshots

To Reproduce
Attention to detail is important!

1. light forge.
2. allow fuel to burn out and down so temperature is dropping.
3. use bellows at any point bellow what i assume on the forge;s temperature gauge to be either bright red or the least dark red.
4. so long as bellows are used temperature will remain at this level.
5. if the forge is allowed to cool fully then effect does not occur.
