ABSTRACT:
The present invention relates to a process and a device for preheating by combustion gases, a combustive gas intended to be mixed with a combustible gas before its combustion, comprising a box member containing a first, upper vertical exchanger in which the combustive gas is first heated by heat-exchange in counter-current relationship to itself and then in co-current relationship to the combustion gases, and a second exchanger incorporated in a burner and arranged below the first exchanger, the second exchanger allowing the combustive gas to be heated by heat exchange in co-current relationship and then in counter-current relationship to the combustion gases to finally be mixed with the combustion gas.
