  • Publication number: 20090199837
    Abstract: A combustion chamber of a combustion system comprises a combustion space, a support structure, a heat shield, and at least one through-opening. The heat shield has at least two segments, and each segment has an edge region, a gap communicating with the combustion space being formed between edge regions of adjacent segments, and a retaining device. The adjacent segments include a support element disposed in a bottom region of the gap. The retaining device fixes the respective liner element on the support structure via the respective support element. The at least one through-opening communicates with the gap so as to enable a cooling gas to flow through the through-opening. The at least one through-opening is disposed in at least one of the respective edge region and the support element at the bottom region of the gap.

  • Publication number: 20090095276
    Abstract: A charcoal starter is provided that is fully consumable through combustion. The starter takes the form of a container that includes one or more walls that define a top and bottom compartment. Solid fuel is deposited in the top compartment and kindling material is deposited in the bottom compartment. The divider allows for oxygenation and ventilation while also supporting the solid fuel in the top compartment. The starter is generally composed of a cardboard or other flammable, non-toxic material. The starter is configured such that solid fuel is supported in the top compartment for a period of time after the kindling material is lit and thereafter collapses and is completely consumed. Associated methods for igniting solid fuel, e.g., charcoal, are also disclosed.

  • Patent number: 6951214
    Abstract: A top section for an oven formed with an outer support shell, an intermediate insulating layer and an inner refractory lining wherein the three layers are connected by a plurality of spaced members. The spaced members are preferably formed as stainless steel pegs welded to an inner surface of the outer support shell extending across the intermediate insulating layer and fixed to the inner refractory lining as a result of the cast refractory lining setting around the pegs. The pegs may be covered at least in part by a plastic tip or coating to provide a relative expansion capacity between the pegs and the refractory lining. The outer section is preferably formed from steel, may be any suitable shape and includes one or more apertures to form doorways, flues and access ports for accessory items such as char-grilles, lights, fire retardant systems and windows. The invention extends to an oven including a top section as disclosed.

  • Patent number: 6922033
    Abstract: A cooking apparatus for controlling the opening of a cover over a barbecue grill includes a motor for opening and closing the cover over the barbecue grill, with the motor connected to the cover by a coupling rod. The cooking apparatus includes, in one embodiment, a counterweight attached at the rear of the barbecue cover. The cooking apparatus also comes with a remote control for transmitting control signals to the motor. The remote control transmits start and stop signals to the motor, or alternatively, the motor operates only during the transmission of control signals to the motor. The remote control may also transmit signals to control flow of a combustible gas. The barbecue cover opener is removable from the barbecue grill. Control of the motor allows movement of the cover to stop at any point within the full range of the cover being opened or closed.

    Abstract: A fireplace system, constructed of modules including a firebox, a chimney housing, and a base, each module substantially a block of foam. The firebox has a fire cavity which is lined with fire resistant board to protect the foam from direct exposure to heat. The chimney housing has a central bore and a flue extending concentrically therethrough which has an inner tube in communication with the fire cavity and a concentric and spaced outer tube which is attached to the central bore to impede the flow of heat from the inner tube to the foam chimney housing. The chimney housing, base, and firebox are selectively attached together using connector sets which each include a pair of connection devices, one of which is partially submerged and anchored within the foam of each of the modules to be joined. The modules are joined by mating the connection devices of each connection set.
