摘要:
A barbecue grill and a burner assembly are disclosed, the burner assembly having a venturi tube for conveying gas to the burner, a burner tube having front and back manifolds, with the venturi tube connected to the front and back manifolds and having flow restrictors at the connection interface to at least partially inhibit entry of gas into the front manifold.

An emitter tube has an outer surface and an inner surface, wherein the inner surface defines a cavity of the emitter tube, and the cavity of the emitter tube is adapted for receiving food. An outer tube has an inner surface that defines a cavity of the outer tube, and the emitter tube is positioned in the cavity of the outer tube. A heating unit is for heating the outer surface of the emitter tube so that heat energy is transferred by conduction from the outer surface of the emitter tube to the inner surface of the emitter tube, and the inner surface of the emitter tube emits infrared radiant energy into the cavity of the emitter tube so that a majority of the energy that is transferred to the food within the emitter tube is in the form of infrared radiant energy.

Cooking grates and grills incorporating such cooking grates are provided. A representative cooking grate includes: a plurality of elongate elements of heat resistant material, the elements being V-shaped in transverse cross-section, each of the elements having a first lower edge, a second lower edge and a vertex, the first lower edge and the second lower edge being spaced from each other with the vertex being located therebetween, the vertex being operative as a cooking surface to support food during cooking on the cooking grate; corresponding adjacent lower edges of adjacent ones of the elements being oriented to define gaps therebetween such that a first of the gaps, defined by a first lower edge of a first element and a second lower edge of a second element, exhibits a width of between approximately 5% and approximately 18% of a distance between the first lower edge and the second lower edge of the first element.
摘要:
An infrared emitter (34) at least partially defines an interior space that at least partially contains convective products of combustion. A burner (32) provides a mixture of combustible gas and primary air to the combustion, while secondary air is also provided to the combustion. A first side of the infrared emitter is in opposing face-to- face relation with the interior space so that the first side of the infrared emitter is exposed to, and heated by, the convective products of combustion. As a result, a second side of the infrared emitter emits infrared radiation. Static gauge pressure, measured at a location that is within the interior space and adjacent to the first side of the infrared emitter, may not exceed about 0.009 inches water column while the burner is operating. Excess air present in gasses exhausted from the interior space may be less than 300% while the burner is operating.
