Abstract
The invention relates to a method for heating a furnace comprising at least one burner capable of operating on an oxidant the oxygen content of which can vary; in a first period (P,) the burner is supplied with practically pure oxygen so as to provide a large amount of energy for heating, in a second period (P,) the burner is supplied with an oxidant, the oxygen content of which can vary between about 100% and 21%, in a third period (P,), the burner is supplied with an oxidant, the oxygen content of which is minimal, and which corresponds to a pilot period which requires only a small amount of heating energy. This method makes it possible to optimize the use of the furnace according to the desired thermal performance and oxidant operating costs.
