Composting results in a lot of chemical reactions going on. These reactions result in a lot of heat being generated.

That said, that’s usually not smoke. It’s steam. While compost piles do get hot they are (supposed to be) really moist. It’s certainly possible for that to be smoke, and a compost pile can ignite, but that’s rare and means something has gone wrong.
