Abstract

The invention relates to a method and a burner in which a proportion of the fuel is delivered via an outer annular duct and accelerated at the outlet end to a high speed, while a further proportion of the fuel is delivered via a second, inner annular duct and retarded at the outlet end to a slow speed. This results in stabilization and regulation of the principal flame by a permanent pilot flame.
