A heating device configured to heat an object including an emitter of thermal radiation; and a radiating plate defining a propagation surface to face the object, and an absorption surface for adsorbing the thermal radiation coming out of the emitter; the radiating plate is not in contact with the emitter, so as to be heated by irradiation, and not in contact with the object, so as to heat it by irradiation.

An outdoor, free standing area heater comprises a vertically extending housing defining an interior and a heat producing source for producing a flame that heats air and at least one glass tube directing at least a portion of the heated air upwardly inside the housing. An upper hood is located above the housing at a position for the heated air conducted by the at least one glass tube to impinge on the upper hood, the upper hood being shaped to redirect the heated air in a direction away from the housing and in a general downward direction from the upper hood. The glass tube is substantially surrounded by side panels that are provided with a plurality of cutouts in a wall defining each of said side panels, wherein the cutouts leave a percentage closure of the wall in the range from 1 to 65 percent.

A methodology and product or system configurations are provided which allow food to be directly irradiated for cooking applications which involve the impingement of direct radiant energy on food or comestible items. Cooking vessels or cook-packs are used that are optically transmissive in visible or infrared narrow wavelength bands emitted in suitable narrowband cooking or heating systems.

An infrared ray generation mesh adapted to a combustion device comprising a mesh body which includes a first surface and a second surface positioned back-to-back, and a peripheral edge which has a first part and a second part on opposite sites. Wherein, the mesh body is bent or folded integrally to form a plurality of corrugations, each of the corrugations extending from the first part to the second part; and the mesh body is flame heated to generate infrared rays. Whereby, the infrared ray generation mesh improves accumulation of thermal energy generated by open fire, such that the heating range of infrared rays is getting wider and the infrared intensity per unit area is higher to achieve better heat control.

A system for direct injection of selected thermal-infrared (IR) wavelength radiation or energy into food items for a wide range of processing purposes is provided. These purposes may include heating, raising or maintaining the temperature of the food articles. The system is especially applicable to operations that require or benefit from the ability to irradiate at specifically selected wavelengths or to pulse or inject the radiation. The system is particularly advantageous when functioning at higher speeds and in a non-contact environment with the target.

A combustion device includes at least one burner, a supporting assembly, and an infrared ray generation assembly. The at least one burner includes a flame outlet and is adapted to burn gas. The supporting assembly includes a cover plate which has an opening and a plurality of holes, wherein the opening is corresponding to the flame outlet. The infrared ray generation assembly is disposed on the supporting assembly. The infrared ray generation assembly includes an infrared ray generation mesh which includes an emission surface which is adapted to emit infrared ray and corresponding to the plurality of holes. The heating efficiency of the combustion device can be effectively increased by generating an open fire and infrared rays as well as uniform heating.
