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.

A method and system can include: providing a grill body; mounting a cross-flame burner within the grill body, the cross-flame burner including an arched extension, a longitudinal portion, and a gas conduit, the arched extension extending laterally from the longitudinal section, the cross-flame burner including burner ports within the arched extension for providing a flame from a fuel and air mixture from the gas conduit; and affixing a Venturi body to the gas conduit.

An infrared heater for use in an agricultural setting, particular for use in poultry houses, is provided that includes a burner assembly supported by an opposing pair of generally T-shaped end plates. The heater further includes a pair of emitter assemblies having a parabolic configuration that are each supported by an elongated emitter support. The emitter assemblies surround an inner core member assembly that in part define burn chambers. The heater includes a pair of end deflector members that together with the parabolic inner surfaces of the emitter assemblies direct infrared heat outwardly and downwardly in a wide and generally quadrilaterally shaped heat footprint.

A method and system can include: providing a grill body; mounting a cross-flame burner within the grill body, the cross-flame burner including a horizontal extension, a longitudinal portion, and a gas conduit, the horizontal extension extending laterally from the longitudinal section, the cross-flame burner including burner ports within the horizontal extension for providing a flame from a fuel and air mixture from the gas conduit; and affixing a Venturi body to the gas conduit.

Embodiments disclosed herein are directed to devices and methods for improving operation of a combustion system. According to various embodiments disclosed herein, a prefabricated integrated combustion assembly is disclosed that may be installed into a combustion chamber of a combustion system. The combustion system may be a new combustion system that is being manufactured or a conventional combustion system that is being retrofitted.

The disclosure relates to a gas-heated infrared radiation emitter comprising at least one radiating screen, which is for example made of ceramic and/or metal, in the form of at least one plate comprising a lower main surface and an upper main surface that are distant from each other, and a plurality of through-prisms, which are preferably hollow, extending from the lower main surface to the upper main surface, each prism being defined by a polygonal base and by an axis. The prisms may be juxtaposed with one another so that their polygonal bases form a tiling of at least one portion of the lower and upper main surfaces of said plate.
