The present invention generally provides an improvement upon existing wood-gas stoves, in which the invention makes it possible for a user to start the fire in a well-ventilated single-walled stove configuration, and then easily and instantly convert the stove into a double-walled wood-gas stove configuration for improved start-up and boil times as well as increased fuel efficiency of the stove and reduced smoke particulates emanating therefrom. The invention also improves air flow and pyrolysis efficiency by elevating the canisters above the surface below, allowing less restricted air flow from underneath and a greater distance and time for gas to heat up between the canister walls.

A modular outdoor fireplace and brick oven system is configured to be easily transportable and assembled. The modular system has a chimney unit and at least one modular unit. The modular unit may be one of an oven unit and a fireplace unit. The chimney unit and at least one modular unit are uniquely aligned using a plurality of alignment means. The alignment means are disposed between the assembled units on a top surface and a bottom surface of each modular unit and the chimney unit. The modular units are designed to allow airflow from each modular unit to reach the chimney unit. The modular units may further have lifting holes designed to easily move the modular units or assembled system with a forklift, lifting straps, and slings.

The present fire pit system includes a fire pit stand including a body including a plurality of openings, wherein the walls of a fire pit body can rest upon the fire pit stand. The fire pit stand protects below surfaces (e.g., floor, ground, etc.) from high heat. The openings in the fire pit stand increase airflow. The fire pit stand fits inside the fire pit body creating a portable unit. When the fire pit is being assembled, the fire pit stand can be removed from inside the fire pit body, placed on the ground, and the fire pit body can be placed on top of the fire pit stand.

A combustion device includes a combustion chamber with an outer wall enclosing a combustion space that can contain a fuel source on an adjustable fuel rack, side walls, a lower air jet tube and at least one air upper jet tube, a top opening, a grill top assembly to cover the opening, and a detachable power module. The power module can have batteries and a blower. The blower can force ambient air into a manifold, through the jet tubes, through ports in the jet tubes, and into the combustion chamber.

An outdoor cooker and a kit of parts for assembling an outdoor cooker are disclosed. The outdoor cooker includes a fire pit, a vertical support mechanism for coupling to the fire pit, a cooking grill for coupling to the vertical support mechanism above the fire pit, and a mechanism for coupling to the vertical support mechanism that is operative to selectively move and secure the cooking grill to a desired position along the vertical support mechanism.

A portable base and grill assembly with few parts, that is collapsible, robust, and easily portable and storable is provided. The base includes two parts: a collapsible frame for containing combustion and an insert for holding combustible material including wood and charcoal. The portable grill includes two parts: a collapsible stand and a cooking surface. The cooking surface is a mil-able grill that can support cookware or be used to cook food directly. The height of the stand may be adjusted to raise or lower the cooking surface above a heat source. The portable base, portable grill and cooking surface may each be used as a standalone apparatus or combined and used together as in the assembly. The base and grill assembly may be constructed wholly of stainless steel for durability.
