Sorry did not read all the posts on this subject but thought I would offer this. I burned corn for 4 years did not have any problems with it. Buy your corn at a coop in a wagon if you can find one reasonable in price than make a screen set at a angle so the fines will fall out, that will save a lot of problems that some people will have with auger set ups. Corn burners with auto clinker removal would be better but I do mine manual and never have to restart it. Big problem is when power goes out exhaust will stink house up cause no fan blowing to out side. Corn has more BTU's than pellets and in my area pellets are expensive. I also am set to burn wood and propane so I can keep up with price fluxation from propane.
