Abstract
An infrared radiation source is provided by directing combustion gases through a honeycomb mantle along the axis of symmetry thereof. The honeycomb mantle is formed of individual tubes disposed at an angle to the axis of symmetry of the mantle and is closed at the end away from the combustion gas input. The mantle may contain a structure to divert the combustion gases therein to aid in uniform heating.
Claims16
A combustion heated honeycomb mantle infrared radiation source, comprising:
- a combustion heated mantle formed of a material which when heated emits radiant energy, said mantle including walls of a honeycomb structure with the axis of symmetry of the holes of said honeycomb walls being disposed at an angle of less than 180.degree. with respect to the longitudinal axis of said mantle, said mantle being open at one end and closed at the other end;
- a diverter disposed at the closed end of said mantle;
- and
- means for heating said mantle with combustion gases.
