ABSTRACT:
A far-infrared radiating system comprises a far-infrared radiating element (2) such as a ceramic, adhered to a metallic material (1) and radiating far-infrared rays upon heating. The system is constructed of a primary-radiating element (5) which is made of a metallic material while heated by a combustion gas passing therethrough and a secondary-radiating element (3) provided with the far-infrared radiating element (2) adhered to the metallic material (1). The primary-radiating element (5) is spaced apart and oppositely disposed from the secondary-radiating element (3) which is heated by infrared rays radiated from the primary-radiating element (5) having been heated with a combustion gas passing therethrough, whereby the secondary-radiating element (3) radiates far-infrared rays.
