Burning corn involves a bit more owner interaction than (say) a gas furnace. These are pictures of some of the transport and cleaning stuff you will need, as well as a few corn stoves.
These pictures are mostly from pictures posted on the Yahoo Groups Cornfuel group (a very active and interesting group).
You need to remove the dust and odd bits of cob from the corn before burning it.
Here is one very simple corn cleaner.

You need to have a way to transport the corn (or have it delivered), and a place to store it once it arrives.
And, ideally, a way to transfer it from the big storage bin to the hopper associated with the actual cornburner.

This system uses a vacuum hose to transfer corn from the outside storage hopper to the small inside storage hopper next to the corn burner.
Corn burners come in many shapes and sizes. Some are similar to pellet or wood stoves and can be installed in the living area. Others are more like furnaces.
Here are a few samples -- a Google on corn burners or corn stoves or corn furnaces will turn up a lot more.
