Flue Flow Regulator
 ✖  |
An overheated wood stove scared Fred Bucheit, Beech Creek, Penn., into the development of an automatic "flue flow" regulator that automatically maintains a proper air flow into the burning chamber by monitoring flue temperatures.
The regulator replaces a conventional barometric unit that's designed to let room air into the flue when the pressure inside decreases due to high temperatures. Bucheit says the barometric units often don't work fast enough so that by the time they open up there's already a problem. His device makes use of an automotive choke coil mounted in place of the barometric sensing unit and connected to the flapper by a rod linkage.
"As temperature increases in the flue, the choke coil opens up instantly, opening the flapper and letting air down into the stove, stabilizing the fire and preventing overheating. As the flue cools down, it'll instantly shut down," says Bucheit, noting that an easy adjust dial on the choke coil makes it a simple matter to adjust the temperature of the stove.
"Maintaining a more consistent burn also helps reduce creosote buildup in the chimney," says Bucheit, who's looking for a manufacturer for his patented device.
