Double Fire Pot Patents (Class 126/2)
  • Patent number: 11944236
    Abstract: A solid fuel cooking range is described herein. Embodiments enable the user to cook food on an upper grill while simultaneously heating a separate dish in a lower oven. In certain embodiments, heat may be applied to the oven from both the top and bottom. Heat and airflow may be controlled using a shroud which does not enclose the sides of the upper cooking area and separate end plates. Embodiments may be portable and lightweight which enables the solid fuel cooking range to be used while traveling and in emergency situations.

  • Patent number: 9585518
    Abstract: A cooker includes a cooking chamber having a first end and a second opposite end. A firepot is located at the bottom of the cooking chamber near the first end. The firepot receives and burns fuel to heat the cooking chamber. An exhaust stack is mounted near the second end of the cooking chamber. A heat management plate divides the cooking chamber into a lower fire pit portion and an upper cooking portion. The heat plate has an array of hot gas convection openings that extend between a first location which is spaced away from the firewall and a second location that is adjacent to the stack wall. The open area presented by the openings increases between the first location and the second location. An optional adjustable gate may also be present in the heat management plate between the firewall and the first location.

  • Patent number: 8899222
    Abstract: A combustion chamber, having an upper part and a lower part, may include an annular constriction, in combination with the combustion chamber, to aid in directing partially combusted gases such as carbon monoxide away from the periphery of the combustion chamber back toward its center, and into the flame front. The annular constriction may also impede the flow of partially combusted gases located at the periphery, thus increasing the time these gases spend within the combustion chamber and increasing the likelihood that any products of incomplete combustion will undergo combustion. The combustion chamber may further comprise a dual burner cooktop for directing combustion gases and exhaust to multiple cooking vessels. In further embodiments, the combustion chamber may be made of, lined, or clad with a metal alloy comprising iron, chromium, and aluminum.

  • Publication number: 20080230044
    Abstract: Devices and methods for accelerating the combustion of non-gas cooking fuels used in barbequing. The devices include a starting fuel for preparing, or starting, a cooking fuel, such as charcoal briquettes, for use to cook food. The starting fuel is contained in a kindling chamber beneath an upper chamber containing the cooking fuel. A powered air delivery mechanism may provide an airflow to the fuels to increase combustion and heating thereof. In some embodiments, the device is a breach-loading device. In some embodiments, the air delivery mechanism is battery-powered. The device may be configured to provide, and/or may be automated to provide, different operating states responsive to the degree of ignition and/or combustion of the fuels in the device. In some embodiments, the device is adapted to automatically be transitioned between forced-air and natural-draft operating states, which may be controlled responsive to sensed operating parameters of the device.

  • Patent number: 6964273
    Abstract: An outdoor cooking apparatus includes a main burner section and an auxiliary burner section connectable thereto. A user can cook outdoors with either a single burner arrangement using the main burner section or a double burner arrangement using the main burner section and the auxiliary burner section connected thereto. Upon assembly, the burner sections each provide a burner element that are at respective differing elevational positions, the main burner section providing a burner element at a higher elevation and the auxiliary burner element providing a burner at a lower elevational position. The two burner sections are removably connectable so that the auxiliary burner section can be either connected to or disconnected from the main burner section as selected by a user.

  • Patent number: 4730597
    Abstract: A biomass stove has an outer chamber formed by a continuous side wall which is connected to a bottom wall. An air inlet is formed in the bottom wall for allowing introduction of air into the interior of the outer chamber. A fuel basket, also formed as a continuous side wall attached to a bottom wall, is located within the outer chamber. In the fuel basket, near the bottom of the fuel basket, a grate is positioned. First and second reflecting members are positioned below the grate within the fuel basket. Air inlets are located along the bottom periphery of the fuel basket with primary air flowing up through the air inlets and over the reflecting members and through the grate into a fuel supply which can be located within the fuel basket on the grate. One or more of the primary stoves can be suspended in a support housing to form an appropriate multi-burner stove.
