Abstract
Abstract A radiation burner or glow radiator, in which a combustible mixture of gas or fuel vapor and air is supplied from a distribution chamber to a permeable burner head, which comprises an insulating layer of heat-resisting and/or fireproof material, for instance a fiber fleece, provided with discrete passage apertures for the combustible mixture, the burner head also comprising a heat-radiating surface of heat-resisting and/or fireproof material, consisting of one or more hollow moulded bodies provided with outlets, in such a way that burning gases issuing from these outlets impinge upon an external surface of an adjacent region of a heat-radiating surface.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
215 words
A radiation burner, comprising: a casing defining a distribution chamber, means for supplying thereto a combustible mixture of air and gas or fuel vapor, an insulating layer of heat-resisting material formed of a fibrous fleece, said insulating layer covering said distribution chamber, and being formed with discrete apertures serving as passages for the said combustible mixture, and a burner head consisting of hollow body means located on the outer side of said insulating layer, each of said body means including a wall bounding a combustion chamber and having an external heat-radiating surface, this wall being formed with outlets for hot combustion gases, so arranged that the hot combustible gases, after leaving the said combustion chamber through such outlets, impinge upon an external heatradiating surface of a combustion chamber, which is also internally heated by the combustion of gases or vapors therein, and wherein the hollow molded body means consisting of a plurality of tubular molded bodies, each being formed with open outlet apertures at two opposite ends, each of the passages through the insulating layer leading to an inlet located between the opposite ends of one of the molded bodies, and the tubular bodies being arranged in staggered relationship to one another so that the outlet apertures of adjacent tubular bodies point in different directions.
Claim 2
Dependent Claim
215 words
A radiation burner, comprising: a casing defining a distribution chamber, means for supplying thereto a combustible mixture of air and gas or fuel vapor, an insulating layer of heat-resisting material formed of a fibrous fleece, said insulating layer covering said distribution chamber, and being formed with discrete apertures serving as passages for the said combustible mixture, and a burner head consisting of hollow body means located on the outer side of said insulating layer, each of said body means including a wall bounding a combustion chamber and having an external heat-radiating surface, this wall being formed with outlets for hot combustion gases, so arranged that the hot combustible gases, after leaving the said combustion chamber through such outlets, impinge upon an external heatradiating surface of a combustion chamber, which is also internally heated by the combustion of gases or vapors therein, and wherein the hollow molded body means consisting of a plurality of tubular molded bodies, each being formed with open outlet apertures at two opposite ends, each of the passages through the insulating layer leading to an inlet located between the opposite ends of one of the molded bodies, and the tubular bodies being arranged in staggered relationship to one another so that the outlet apertures of adjacent tubular bodies point in different directions.
Claim 3
Dependent Claim
33 words
A radiation burner as claimed in claim 1, the tubular molded bodies being formed not only with outlet apertures at their opposite ends but also with further outlet apertures in inner wall surfaces.
Claim 4
Dependent Claim
219 words
A radiation burner, comprising: a casing defining a distribution chamber, means for supplying thereto a combustible mixture of air and gas or fuel vapor, an insulating layer of heat-resisting material formed of a fibrous fleece, said insulating layer covering said distribution chamber, and being formed with discrete apertures serving as passages for the said combustible mixture, and a burner head consisting of hollow body means located on the outer side of said insulating layer, each of said body means including a wall bounding a combustion chamber and having an external heat-radiating surface, this wall being formed with outlets for hot combustion gases, so arranged that the hot combustible gases, after leaving the said combustion chamber through such outlets, impinge upon an external heat-radiating surface of a combustion chamber, which is also internally heated by the combustion of gases or vaporS therein, and wherein each combustion chamber is in the form of a triangular prism, with an outlet recess in the form of a notch in the end of one slant side at one end of the prism and a similar recess in the other slant side at the opposite end of the prism, the combustion chambers and their notches being so arranged that combustion gases issuing from the said notches impinge upon unnotched heat-radiating surfaces of adjacent combustion chambers.
Claim 5
Dependent Claim
219 words
A radiation burner, comprising: a casing defining a distribution chamber, means for supplying thereto a combustible mixture of air and gas or fuel vapor, an insulating layer of heat-resisting material formed of a fibrous fleece, said insulating layer covering said distribution chamber, and being formed with discrete apertures serving as passages for the said combustible mixture, and a burner head consisting of hollow body means located on the outer side of said insulating layer, each of said body means including a wall bounding a combustion chamber and having an external heat-radiating surface, this wall being formed with outlets for hot combustion gases, so arranged that the hot combustible gases, after leaving the said combustion chamber through such outlets, impinge upon an external heat-radiating surface of a combustion chamber, which is also internally heated by the combustion of gases or vaporS therein, and wherein each combustion chamber is in the form of a triangular prism, with an outlet recess in the form of a notch in the end of one slant side at one end of the prism and a similar recess in the other slant side at the opposite end of the prism, the combustion chambers and their notches being so arranged that combustion gases issuing from the said notches impinge upon unnotched heat-radiating surfaces of adjacent combustion chambers.
