    摘要： The present invention provides a process for operating a combustion furnace, wherein the combustion furnace comprises a combustion chamber defining a combustion zone within the combustion chamber and having at least one chamber wall facing the combustion zone, and at least one particulate fuel burner mounted in a chamber wall and adapted to generate a flame in the combustion zone by injecting oxidant in gaseous form and fuel in particulate form into the combustion zone for combustion therein. In the process, at least one particulate fuel burner is operated so as to alternate between a first phase in which the burner generates a wide flame proximate the chamber wall into which the burner is mounted and a second phase in which the burner generates a narrower flame directed away from the chamber wall into which the burner is mounted.

    摘要： A method of combining oxygen and fuel in a burner to produce a flame whereby an outer oxidant flow is discharged through an outer oxidant outlet of the burner; a flow of conveyor-gas propelled particulate solid fuel is discharged with a fuel discharge velocity through a fuel outlet of the burner arranged coaxially with respect to the outer oxidant outlet and spaced radially inwardly therefrom; and a first inner oxidant flow is discharged with an inner oxidant discharge velocity, which differs from the fuel discharge velocity, through an inner oxidant end outlet of the burner arranged coaxially with respect to said fuel outlet and spaced radially inwardly therefrom; and whereby a second inner oxidant flow, having a higher oxygen concentration than the conveyor gas is injected into the fuel-conducting passage and mixed with the fuel flow inside said fuel-conducting passage so as to obtain, upstream of the fuel outlet and upstream of the inner oxidant end outlet, an oxygen-enriched conveyor-gas propelled particulate solid fuel flow having an oxygen content of at least 21% vol O2.
