Other grains
From Cornburning
Make sure you read BTU Values of other grains.
Other grains can be burned in corn stoves without problems. Sometimes some stoves will have feed problems in the auger system that might cause the grain not to be fed into the fire. A good suggestion would be to buy a very small quantity of the grain first to do some trial burns. Make sure the grain burns well and that it feeds through the grain deliver system and into the firepot without jamming or snuffing out your fire.
Many times other grains have different types of garbage in the grain that could cause your stove problems. Oats have straw that could plug the feed auger, but as long as the straw is all removed, they burn great! Oats have close to the same BTU per pound value as corn, but they are lighter (32lbs/bu); meaning you have to burn more. You may find that they will be fine for use in the spring and fall but once the temperatures really drop, your stove could not make enough heat, even with the feedrate to the max.
Another grain that is popular is to burn rye. It burns as hot or hotter than corn. It makes clinkers that look like lava rock. Rye is generally quite cheap to seed and plant, and you can go directly from the field to the stove if you harvest at the right time (no drying like corn).
Barley can also be burned. It weighs 48lbs/bu.
Buckwheat has been tested successfully in a Bixby stove. See the following thread for photograph, discussion, and some data. http://forum.iburncorn.com/viewtopic.php?t=2976&highlight=buckwheat Like rye, it is relatively inexpensive to grow and to harvest. It is commonly grown to improve soils and to smother weeds.
Beet pulp pellets are another option as discussed in the following thread. http://forum.iburncorn.com/viewtopic.php?t=1117&highlight=beet+pellet
Many stoves can burn cherry pits. One thing to be aware of, cherry pits contain cyanide (hydrocyanic acid or called prussic acid). At 300 ppm it will kill a human being in a matter of minutes. The pit also are highly toxic (only if cracked or halved) to small children and pets if ingested. Ingested cherry pits are not digested and will pass through the gut. As long as the cherry pit is not cracked open the poison kernel part of the pit can not be absorbed by digestion. Cherry pits are very hard and opening one with the teeth isn't likely. However, this all said, cherry pits do make a very good fuel and can be obtained very economically as many cherry canning factories give them away as waste product. I imagine they smell real nice in your house too.
There are also Grass Pellets
