Round Stove Design Has Many Benefits Says Inventor ENERGY Wood Burners 65 “If your stove isn’t round it’s not as efficient as it could be ” says Andrew Murray about heating stoves Everything is round in the inventor’s recently patented combustion chamber which he calls an Efficient Solid Fuel Burning Appliance ESFBA FARM SHOW first met Murray at the Minnesota Inventors Congress in 2010 Vol 34 Issue 4 and he has been working on tweaking the design ever since He builds and sells circular stoves from his South Dakota shop to customers who burn wood But he emphasizes the stove has the potential for many applications - burning biofuel and pellets and being used indoors or outdoors as a forced air furnace or boiler for example It could also be used to dry grain or produce steam he adds The heart of the stove’s efficiency is the round cast iron baffle parallel to the fire grate “My baffle holds back heat and smoke increasing the pressure which means higher efficiency for combustion ” Murray explains “My ESPBA benefits from a stronger cylinder shape increase in internal pressure more efficient heat distribution and a smaller footprint compared to similar btu output appliances ” He sells his Dakota Stove set up to burn wood for $2 600 plus shipping It produces 175 000 btu’s and uses one-third less wood than similar-sized stoves The blower automatically adjusts between high low and off The unit is 48 in tall and 36 in dia The chimney is in the middle so the stove can be placed closer to a wall With chimney temperatures averaging 250 to 350 degrees Murray believes his stove eliminates chimney fires “The safety and efficiency is significant especially for the insurance industry And owners are more comfortable operating the stove ” Murray says Currently he builds stoves per customer request He is also interested in connecting with manufacturers about new applications for the ESFBA “It would be a huge benefit to pellet and outdoor stove manufacturers ” he says Contact: FARM SHOW Followup Andrew Murray Dakota Stove 11698 395th Ave Columbia S Dak 57433 ph 605 396-2431; www dakotastove com; Andrew treeguy@gmail com
