    Any food gives energy, so you can either eat some which is packed with chemical burn value (oil/coal/peat…) or just eat a lot of “normal valued” food like humans. Third option is they have really good processing and insulation (humans dump most again because it takes to long to process).

      Yes which is why I don’t think eating a lot of “normal” food would cause this. The amount of having to eat to cause this amount of heat would probably be 100x more than required for their body size, which means that they would never stop eating. I think it’s more likely they consume something itself highly combustible like oil. Or maybe they’re doing internal fission :D

        Not necessary, we it body spend a lot of effort to cool and we do a lot of other stuff. If a dragon is sleeping mostly he doesn’t need so much. Also you don’t need any energy to maintain temperature. You just need enough to compensate for what you use. So let’s say they mostly sleep and have really good insulation, they are fine. Or just sleep in a pit of lava.

        Cold fusion sounds also feasible, given it’s a mystical creature.
