Compact lance burner for gasifying pulverized fuel, has nozzle element including multiple holes, which are aligned in same angle at middle line of guide elements such that holes supply oxidant into pulverized fuel flow

摘要

The lance burner has multiple guide elements (6) for guiding pulverized fuel (2) and oxidant (3) to a circumference of the burner. The guide elements directly end adjacent to a burner orifice of a pilot burner (1). The guide elements have a guide pipe for the pulverized fuel and a ring channel (3) for the oxidant. The guide elements have a nozzle element (4) at an end that is attached to the burner orifice. The nozzle element has multiple holes, which are aligned in an angle at a middle line of the guide elements such that the holes supply the oxidant into pulverized fuel flow.
