Abstract
In a far-infrared radiating system, a plurality of radiating units for allowing the combustion gas to pass therethrough are connected in series to form a multi-stage series-connecting construction. The combustion gas releases its heat energy in the form of far-infrared rays when passing through each of the radiating units. The combustion gas having passed through the radiating unit decreases in temperature, and recovers its previous high temperature through combustion of a fuel which is mixed with such combustion gas before the combustion gas enters the following-stage radiating unit. Such combustion is repeated in each of the following stages so that the heat produced by combustion of the fuel is effectively radiated in the form of the far-infrared rays without making waste.
