The disclosure relates to a gas-heated infrared radiation emitter comprising a burner plate, the burner plate serving as a combustion surface, and a radiating screen positioned on the combustion surface side of the burner plate. The radiating screen is formed by a mesh material or material with open pores, and has an inner face oriented towards the combustion surface side of the burner plate.

The inner surface of the screen comprises at least a first portion and a second portion offset from one another in relation to the combustion surface, such that the distance between the combustion surface and the first portion is less than the distance between the combustion surface and the second portion.

One or more embodiments relates to a portable, personal device for providing cooking and power and adapted for use with a burner, the device including a plurality of metal-supported solid oxide fuel cells (MS-SOFCs) coupled together; a microelectronic control circuit connected to at least the MS-SOFCs; a light source coupled to at least the microelectronic control circuit; and at least one USB port coupled to at least the microelectronic control circuit; whereby the device is able to simultaneously provide light and power a personal device.

A plaque for a radiant heating system can include a main body defining an outer surface and a plurality of pores defined within the main body, wherein at least some of the plurality of pores are disposed in a non-parallel relationship with at least some others of the plurality of pores, or wherein at least some of the pores are parallel with each other. A burner assembly including a plurality of adjacently arranged plaques reduces the ignition time and delay for adjacent plaques after the central plaque has been ignited.

A parasol heater having a housing with a fuel connection adapted to be coupled to a gas fuel supply is described. The heater includes a pole extending upwardly from the housing and adapted to support a gas burner arrangement, the burner arrangement being provided below a parasol adapted to deflect heat generated by the burner downwardly about the pole, the parasol being rotatable relative to a longitudinal axis of the pole.

A balanced high efficiency outdoor heater is provided to increase the heat radiation area, and to improve the stability of the structure. The heater includes a burner provided at an upper end of a standing column, a bottom base provided at a lower end of the standing column, and a beam is set between the burner and the standing column. The beam and the standing column are connected by pipe fittings. An ignition control device is equipped inside the base and is connected to the burner. An electrode rod and a thermocoupler are connected to the ignition control device under the burner. A first reflector is fixedly connected to the lower end of the burner and a gas valve is equipped in the bottom base. Compared with the prior art, the burner uses sintered felt and a heating surface of the burner faces upside down to improve thermal efficiency.

A patio heater, has: a base to be supported on a ground; a stem protruding upwardly away from the base; and a heat generating device secured to the stem, the heat generating device having: a burner fluidly connected to a source of a fuel to be burned; a diffusion sheet enclosing a combustion chamber, the burner located inside the combustion chamber and surrounded by the diffusion sheet; a reflective shield located above the diffusion sheet; and at least one reflective fin mounted to the diffusion sheet and extending away therefrom.

A gas fired infrared burner includes a burner body with a primary inlet for gaseous fuel and air, the burner body defining a primary premixing chamber for receiving gaseous fuel and air from the primary inlet. An emitter arrangement is configured and positioned such that gaseous fuel and air flows through the emitter arrangement to be combusted at an external surface of the emitter arrangement. The burner body includes an auxiliary inlet for gaseous fuel and air, and the burner body defines an auxiliary premixing chamber for receiving gaseous fuel and air from the auxiliary inlet. The emitter arrangement includes an auxiliary emitter segment that receives gaseous fuel and air from the auxiliary premixing chamber such that combustible gases emitted from the auxiliary emitter segment can be ignited even when no combustible gases are being emitted from portions of the emitter arrangement that are fed from the primary premixing chamber.

A radiant area heater includes a columnar base with a hollow compartment and a heating column disposed on the columnar base. The heating column includes a control portion with at least one controller, a burner, and a sparker and a flame portion that includes a combustion chamber. The combustion chamber is disposed on a cylindrical member that has at least one vent allowing air to circulate to the burner and within the combustion chamber. The heating column further includes at least one heat emitting screen disposed above the flame portion that radiates heat outwards from the heater. A cover is disposed over the heating column to direct heat outwards and away from the heater.

A heater includes a body, a burner assembly, a gas tank, and a reflecting plate. The burner assembly is installed on the body. The gas tank is arranged in the body and directly below the burner assembly, and has an interface end connected to a fuel inlet end of the burner assembly via a valve. The reflecting plate is installed in the body and located between the burner assembly and the gas tank. The reflecting plate prevents heat coming from a bottom portion of a burner of the burner assembly from being radiated directly to the interface end of the gas tank and allows heat coming from around the burner to be radiated to a periphery of the interface end of the gas tank and heat the gas tank.

A plaque for a radiant heating system can include a main body defining an outer surface and a plurality of pores defined within the main body, wherein at least some of the plurality of pores are disposed in a non-parallel relationship with at least some others of the plurality of pores, or wherein at least some of the pores are parallel with each other. A burner assembly including a plurality of adjacently arranged plaques reduces the ignition time and delay for adjacent plaques after the central plaque has been ignited.
