An electric grill configured for cooking food and a method of cooking food using the electric grill includes a housing that defines an open interior and an aperture. Element frames are positioned at the sides of the open interior. Electric heating elements are positioned within the element frames and are positioned within the open interior exterior of the aperture in a direction towards the housing. The electric heating elements generate IR energy that is directed towards a middle of the open interior below the aperture. Heat energy exits the housing through the aperture by radiative heat transfer and convective heat transfer. Such convective heat transfer includes air currents circulating within the open interior past the electric heating elements and out of the aperture.

An electrical radiation heater arrangement for a vacuum enclosure includes at least two sets of linear heating sources, arranged in a corresponding number of concentric heating zones. The heating sources are arranged directly on the vacuum side of the vacuum enclosure and electrically connected to current rails arranged on the vacuum side with each of the current rails being connected to one electrical feedthrough from vacuum to ambient. Preferably, the heating sources are arranged in a polygon approaching a circle, essentially radially or a combination of both.

Provided is a cooking apparatus. The cooking apparatus includes a counter, a burner arranged to protrude upwards from the counter to heat a food container, and a grate arranged on top of the counter to support the food container. The cooking apparatus also includes a simmer plate formed of a glass material and arranged between the grate and the burner to retard transfer of heat produced from the burner to the food container, and a support arranged on top of the counter to support the simmer plate.

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 radiation heater includes: a combustion chamber having a combustion space that is open on one side; a combustion device provided in the combustion chamber to combust air-fuel mixture made by mixing fuel with air; and a radiator configured to be heated by heat generated from the combustion device and including a radiation plane configured to emit infrared radiation. The combustion device includes: a nozzle provided in a flow path of the air to inject the fuel; a tubular body including a side surface that faces a direction with a predetermined angle with respect to the radiation plane, and a plurality of voids being formed on the side surface; and an ignition device provided outside of the tubular body and configured to ignite the air-fuel mixture. The air-fuel mixture flows into the tubular body, and the tubular body releases the air-fuel mixture from the voids into the combustion chamber.

Systems and methods for radiative heat transfer are disclosed. In an exemplary embodiment, an infrared heater comprises infrared heating elements and a controller. The infrared heating elements correspond to respective heating zones. The controller causes the infrared heating elements to turn on at different time in succession such that respective heating zones are radiatively heated at different times. In some instances, the respective heating zones correspond to different heating zones of a user, and the user feels a heating wave effect as the infrared heating elements are turned on and off at different times.
