I had a corn stove and yes you're right burns hot.I had never thought of the comparison before. Lots of shops here have waste oil burners but I did have a customer that had a corn burner. It really burned hot and didn't seem to use a lot of corn (but I don't know that for sure.)
I had a bunch of Rye and burnt that in the stove for a short time and it's even hotter burning than corn.
