| 61 | Low emission woodstove | US13397330 | 2012-02-15 | US08869788B2 | 2014-10-28 | Corey Dewayne Brooks; Brandon Lane Barry |
| The present disclosure provides woodstoves that, optionally, produce low emissions. In certain embodiments, the woodstove includes a housing, a firebox disposed in the housing, an air regulator and a secondary air pipe. The air regulator includes a primary air aperture configured to supply primary air to a fire located in the firebox, a plurality of secondary air apertures configured to supply secondary air to a combustible gas emitted by the fire, and a secondary air damper. The present disclosure also provides methods of operating such a woodstove. As measured according to Method 28 of the U.S. Environmental Protection Agency, the weighted average emission rate of the woodstove of certain embodiments of the invention is no greater than about 4.5 grams of particulate emissions per hour. | ||||||

| Stoves fueled by biomass pellets are provided with a grate assembly that supports the pellets for combustion and directs combustion gas into the fire. The grate assembly includes a passive grate of equally or unequally spaced rods. The design of the rods serves to prevent the ash and clinkers from accumulating on the grate in amounts that could reduce the flow of combustion gas into the fire. In one embodiment, the rods define a surface that serves to distribute unburned fuel pellets from a location where they are deposited from a fuel feed conduit. | ||||||
