Can You Burn Corn in a Keystoker K-2 Coal Boiler

Stoker Coal Boilers automatically feed the coal and have controls and pumps just like any conventions boiler. They are intended to be used as a primary heat and often have domestic hot water coils as an added bonus. They can be set up independently or in dual sytem with your existing oil/gas boiler. They can accommodate both hot water base board or steam plumbing.

Hello Oliver, well I think the corn will burn, but it leaves behind a gummy residue that clogs the stoker's grates and is difficult to remove.

So yes it will burn, but I would never recommend it.

Do a search for 'corn' here and you should find another thread or two about it.

It may work but probably not very well as corn burns a lot like wood pellets. Stokers are coal specific, being tuned for it. Straying from the design fuel in any appliance generally will have issues, if not combustion then heat output would be a concern. I would think even if it worked, it's heat output would be in the 50% range compared to Anthracite coal.

I have a mini stoker 80. I have burned corn in it often. It certainly burns different than coal. Ie; air and shaking settings. I find it to be very efficient and cheaper than coal depending on my source of corn. I can burn corn that farmers can't feed so i can clean up the granary floor and such and get my corn for nothing, almost. The thing that is most different during operation is that corn will caramelize and bridge but a poke twice a day takes care of that.
