Abstract:
1. A combustion method in which two burner assemblies are placed substantially horizontally, parallel to one another and symmetrically about a median plane passing between the two assemblies, each burner assembly comprising: a) a fuel injector ( b) first ( wherein: a total oxidizer flow rate introduced into the furnace is distributed among the first, second and third injectors; a predefined part of the total oxidizer flow rate is injected by the second and third oxidizer injectors ( an oxidizer feed system cyclically distributes the predefined part of the total oxidizer flow rate among at least some of the second and third injectors ( the flow rate of the predefined part is either constant or variable with the proviso that, if the flow rate of the predefined part is variable, the flow rate of the predefined part varies more slowly than the cyclical change in flow rates through the second (
