Abstract
In order, for operating the lance burner of a rotary tubular furnace for the production of cement clinker from calcined raw cement meal, to provide an automated regulation method which is optimized in terms of the configuration of the burner flame for all types and quantities of fuels used, according to the invention a regulation method is proposed in which the characteristics of the burner flame are used as measurement variables, and the measurement variables are delivered to a controller which can vary at least three different manipulated variables of the burner, such as the spatial outflow angle and the swirl momentum of the swirled primary-airstream and/or the angle of divergence of the primary-air/jet-air jets emerging from individual nozzles and/or the velocity of emergence and/or swirl component of a stream of fragmentary alternative fuels or secondary fuels which is blown through the burner.
