    摘要: A solid fuel burning device has at least one burn chamber wall, a burn chamber base, and an interior burn chamber. The burn chamber base is capable of supporting a combustible solid fuel thereon. At least one of the burn chamber walls is radially offset with respect to another of the burn chamber walls. At least two longitudinally extending air inlets are formed in the space between a first longitudinal edge of at least one of the burn chamber walls and a second longitudinal edge of another burn chamber wall. Each of the longitudinally extending air inlets tangentially directs an entry of air into the interior burn chamber to induce an interior swirl of air in the interior burn chamber. The interior swirl of air in the interior burn chamber causes a flame of a combusting solid fuel to swirl in the interior burn chamber.

    摘要: An apparatus includes a heat exchange member at least partially defining a passageway, and structure defining a first plurality of holes and a second plurality of holes. The first and second pluralities of holes provide fluid communication from the passageway to the exterior of the apparatus, i.e., to the atmosphere. A blower is operatively connected to the heat exchange member and configured to blow air into the passageway. The apparatus is configured such that, when the heat exchange member is sufficiently positioned with respect to a campfire, air exiting the first plurality of holes is directed downward and away from the campfire and air exiting the second plurality of holes has an upward velocity component.

    摘要: A reverse combustion type combustion apparatus (1) includes a combustion section (2) that combusts fuel in a downward direction, heat exchangers (4, 5) disposed under the combustion section (2), and an exhaust box (6) disposed under the heat exchangers (4, 5). The exhaust box (6) is a molded product made from a synthetic resin material; the exhaust box (6) includes an opening portion (30) for introduction of combustion exhaust gases generated by an upper portion, a fixing portion (33) for fixing the heat exchanger (5), and an inclined bottom portion (35) that collects condensed water generated by the heat exchanger (5); and, at the lower end portion of the exhaust box (6), at least three legs (40) are integrally formed and make the exhaust box (6) stand up by itself.

    摘要: A pellet stove includes a hopper for storing pellets, a basket for receiving the pellets by gravity, a duct for conveying combustion air to the basket, and a conduit for conducting heated air away from the basket. The position of the basket is adjustable, such as by raising and lowering it, or by rotating it, so as to control the number of pellets in the area of most intense combustion. One or more optional burn plates, positioned below the basket, provide platforms on which pellets falling through the basket can burn down to a smaller size. The pellet stove requires no external source of power. The stove so constructed enables quiet, efficient and clean burning of the pellets.

    摘要: A boiler system comprises a housing with a generally cylindrical shape extends between first and second walls to provide a generally cylindrical space. A fire tube is positioned near a bottom of the generally cylindrical housing and extends longitudinally from a first wall of the cylindrical housing to a fire tube end wall. The boiler system also includes a burner with a generally cylindrical housing which defines a generally cylindrical chamber and an end plate. The burner extends into the fire tube, and the fire tube provides a combustion chamber where combustion of an air-fuel mixture is accomplished using the burner. The end plate of the burner is adjustable so as to adjust the flame that extends from within the burner housing into the fire tube.

    摘要: Embodiments include a wood pellet burner unit with a sliding floor hopper. The wood pellet burner unit includes a wood pellet fire pit, a wood pellet kettle burner, a wood pellet barbeque burner, and/or a wood pellet smoker, or the like. The sliding floor hopper includes an upper loading section having an opening therein that receives wood pellets, and a staging section coupled to the upper loading section and stages the wood pellets received from the upper loading section. A sliding floor is disposed atop a staging surface of the staging section and through a slit in the staging section. The sliding floor oscillates between a forward position and a back position. The sliding floor oscillates between a forward position and a back position to automatically and periodically feed the wood pellets to a lower region of the wood pellet burner unit on a continuous basis.

    摘要: A biomass or bio-fuel combustion system is provided utilizing oxygen as the source of combustion. The system generally includes a primary combustion chamber defining an internal space for receipt of the biomass and a directional oxygen injector positioned within the combustion chamber and having a plurality of injection nozzles for injecting oxygen into the internal space, preferably at an angle relative to a longitudinal axis of the combustion chamber. A transfer chamber extends from the primary combustion chamber to a secondary combustion chamber for further combustion of any remaining particulates. A cooling and exhaust system extends from the secondary combustion chamber for drawing off and condensing out any exhaust and moisture contained in the remaining exhaust particulates. A method of burning a biomass of bio-fuel with producing nitrogen dioxide is also disclosed.

    摘要: Slag (28) is formed during the combustion of solid fuels with a lower ash fusion temperature and covers parts of the solid fuel, prevents complete combustion and blocks the air supply, thereby leading to an interruption of the combustion process. According to the invention, the embers and the fusing ashes are mixed by means of a cleaning comb (22) and are discharged from the burner. The burner consists of rotating grate bars (25) which are arranged parallel to one another within the inner walls (1). The cleaning comb (22) moves between the grate bars (25); upwards between the grate bars (25); in direction of the burner opening; downwards under the grate bars; and finally in the direction of the burner flange (7). When the slag (28) adheres to the rotating grate bars (25), it is scraped off by the cleaning comb (22). The fuel supplied to a funnel (8) slides downwards by the force of gravity, the funnel lid (9) opens, and the fuel is pushed onto the grate bars (25) by the plunger (11). The plunger (11) has at least one opening (15) for secondary air (5) which also provides cooling. A blower (13) blows the ashes fallen through the grate bars (25) through a cut-out section in the burner floor (30) opened by the floor trap (20).
