Rocket stove heaters work on that principle. I built one for my house years ago and the thing produces more heat than I could realistically use for basically twigs on the ground in my yard.
Gasifiers work on a similar principle where it uses the gases from the fuel to make an ICE run. They work as well but are very complex.
