Beschreibung
Zusammenfassung:	A facility and method for oxy-combustion of a fuel with preheated industrial oxygen in a chamber (100) of a furnace, said furnace comprising between four and twenty oxy-fuel burners (107, 109), at least a first series of which (107) is aligned in a first direction in a wall (114) of the chamber, facility and method which involve heating a heat-transfer fluid by heat exchange with the smoke discharged from the chamber (100), and which involve heating industrial oxygen by means of the hot heat-transfer fluid in a primary heat exchanger (103) adjacent to the envelope of the chamber (100) and parallel to the first series of oxy-fuel burners (107), the industrial oxygen to be preheated being divided into a plurality of streams of oxygen to be preheated upstream from or in an oxygen inlet area inside the primary exchanger (103), said primary exchanger comprising a plurality of outlets, each oxy-fuel burner (107) of the first series being linked to an outlet (131, 132) of the primary heat exchanger (103) to supply a stream of preheated industrial oxygen to said oxy-fuel burner (107), none of the outlets of the primary exchanger being linked to a plurality of oxy-fuel burners.
