A bright radiator includes a burner, a fan and a radiant panel functioning as a radiating surface and having flame through-channels, wherein the burner is connected to a fuel gas supply, wherein the fan is designed to supply the burner with combustion air, wherein the burner is designed to bring about extensive glowing of the radiant panel, and wherein the fuel gas supply is connected to a hydrogen source as a fuel gas source.

Tubular radiant element for industrial plants and the like, made of a metal material resistant to high temperatures, including at least one vertical tubular portion, optionally at least a curved tubular portion, provided with a surface (S), including at least one radiation and stiffening means arranged on at least a portion of the surface (S) of the tubular radiant element.

The present invention provides a safer all-around radiation heating assembly than similar traditional heaters. As typical with traditional heaters, a shroud is used to surroundably cover a portable liquid propane tank. To replace the portable liquid propane tank, the shroud must be continuously raised to a predetermined height while a service person accesses the propane tank. There is a danger that if and when the shroud drops, a spark could be created resulting in igniting highly flammable escaped propane gas. The present invention overcomes dangers associated with the traditional heaters by eliminating the spark creation danger and by introducing a ventilation system to allow any leaked propane gas to escape away from the heater.

A thermo-photovoltaic system including an infrared radiation emitter including a body including a first external surface and a second external surface, the first and second external surfaces being distinct, the first external surface facing a concentrator for receiving a concentrated solar radiation, the second external surface facing a thermo-photovoltaic cell, and the body further including at least one gas and/or liquid combustion chamber therein, and an igniter is provided for causing combustion in the combustion chamber.

This invention relates to a rotary flame heater, comprising a burner, a first wind wheel, a second wind wheel and a glass tube set in sequence from bottom to top; one side of the burner is set with an ignition device, the first wind wheel and second wind wheel are annular, a plurality of first air inlet passages are aslant set on a side wall of the first wind wheel, a plurality of second air inlet passages are aslant set a side wall of the second wind wheel, the inclined direction of the plurality of first air inlet passages is the same with that of the second air inlet passages. The advantage of this invention is to make full use of the combustion space, increase the contacting area with the glass tube and increase the calorific value when burns the same gas, which achieves a better heating effect.
