Patent ID: 7757685

Claim:
A radiation burner, comprising: a pot configured to burn gas; a mat that extends across an open top portion of the pot, wherein the mat is heated by combustion of gas in the pot and radiates thermal energy; a housing provided on the mat, wherein the housing is configured to allow thermal energy radiated by the mat to pass therethrough; a support member provided on the housing, wherein the support member is configured to support an object thereon; and a barrier provided within the housing, surrounding an outer peripheral portion of the mat so as to concentrate thermal energy radiated by the mat and heat generated by the burnt gas within the housing, and to retard an exhaust of the burnt gas from the housing, the barrier comprising: a first barrier portion positioned proximate to an outer peripheral edge of the mat; and a second barrier portion separated from the first barrier portion in a radial direction by a predetermined interval, wherein the second barrier portion includes a plurality of perforations that guide gas therethrough, wherein a gap between the support member and a top of the first barrier portion is greater than a gap between the support member and a top of the second barrier portion.
