Abstract: A barbeque oven for use with biomass fuel granule and having a stand placable on the ground and a baking cabinet and an auxiliary equipment on the stand. The baking cabinet has a combustion cabinet and a burner received therein. The baking cabinet further has an outer baking box and an inner baking box. The inner backing box has a plurality of heat dissipating opening defined therein. A density of the heat dissipating openings increases from a proximal end to a distal end of the inner baking box. The auxiliary equipment cabinet has a fuel supplying mechanism and an electrical equipment received therein.

Abstract: A biomass fuel simulation fireplace having a body which is able to be placed on the ground. The body has a front simulation fireplace and an oven. The oven has a combustion cabinet and an auxiliary equipment cabinet. The combustion cabinet has a burner received therein. A heat exchange cabinet is above the burner. At least two rows of heat dissipation tubes are in the heat exchange cabinet, each row having at least two heat dissipation tubes. An upright cross wall is between each two the neighboring rows of heat dissipation tubes. The auxiliary equipment cabinet has a fuel supply mechanism and an electrical equipment received therein. The fuel supply mechanism has a hopper, a fuel tube and a rotary vane feeder. The electrical equipment has a heat dissipation air blower, a feeding motor, an air blower, a draft fan, a light source and a motor for the simulation fireplace, a power supply, and a switch.

Abstract: A biomass fuel oven for use with biomass fuel granule. The oven has a body which is able to be levelly placed on the ground. The body has a combustion cabinet and an auxiliary equipment cabinet. The combustion cabinet has a burner received therein. The burner has a fire grate. A burning zone is defined beyond the fire grate and an air supply zone is defined below the fire grate. A plurality of air vents is defined in the fire grate. An air supply device is provided at the burning zone. The air supply device has a tubular inner wall and an air chamber surrounding the tubular inner wall. The air supply zone is in communication to the air chamber and is supplied air by an air blower via an air duct.

Abstract: An oven for use with a variable pitch fuel supplier and for use with biomass fuel. The oven has a body which is able to be placed on the ground. The body has a combustion cabinet and an auxiliary equipment cabinet. The combustion cabinet has a burner received therein and the auxiliary equipment cabinet has a fuel supplier and an electrical equipment received therein. The fuel supplier has a hopper, a fuel tube, and a rotary vane feeder rotatably received in the fuel tube. The electrical equipment has a power supply and a feeding motor driving the rotary vane feeder. Pitches vary larger from a tail end to a free end of the rotary vane feeder.

Abstract: An oven has an enclosed heat exchange zone for use with biomass fuel. The oven has a body which is able to be placed on the ground. The body has a combustion cabinet and an auxiliary equipment cabinet. The combustion cabinet has a burner received therein. The burner has a fire grate, a side plate, a blowing space, and a hearth. A heat exchange zone is defined by the surrounding tubular inner wall; a side heating zone being defined by a tubular inner and a tubular outer walls. A chimney is formed on the tubular outer wall in communication with an upper portion of the side heating zone. An opening is defined in the top of the combustion cabinet right above the tibular inner wall.

Abstract: A bonfire oven has a body placeable on the ground. The body has a combustion cabinet and an auxiliary equipment cabinet. A burner contained in the combustion cabinet has a fire grate, a side plate extending upward from the fire grate, a top plate opposite to the fire grate, a blowing space beneath the fire grate, and a hearth defined by the fire grate and the side plate. A fuel supply mechanism, an electrical equipment and an air blower is contained in the auxiliary equipment cabinet. The bonfire oven further has a flame portion on the top which is a flame roaring space formed by at least one piece of high temperature resistant glass.

Abstract: A high performance burner has a shell, a burning chamber contained in the shell, an ignition bar installed in the shell, and a fuel feeding means passing through the shell and being in communication with the burning chamber. The burning chamber has a first burning zone in communication with the exit of the feeding pipe, a second burning zone next to the first burning zone, and a third burning zone next to the second burning zone and in communication with the rear opening of the shell. The burner is able to effectively reduce fuel congestion, scorification and back fire and increase combustion efficiency.
