Burner for operating an internal combustion engine, a combustion chamber of a gas turbine group or a combustion system

摘要

In a double-cone burner, at least one row of nozzles (10) for a fuel (15) containing highly reactive gaseous components and having a medium calorific value is mounted on the circumference of the partial conical bodies (1, 2) of the burner in the vicinity of the burner outlet, at a distance of about 30% of the nominal diameter of the burner. In addition, there is a fuel line (11) and a distributing channel (17), positioned in the region of the nozzles (10), for the highly reactive fuel. The fuel (15) containing highly reactive gaseous components is injected at high speed through the nozzles (10), which have a diameter of less than 1% of the nominal diameter of the burner, into the zones of high air speed and the depth of penetration and the direction of the fuel jets are matched to one another in such a way that ignition following mixing takes place only after the burner.
