Burner head and method for one-step combustion of fuel in a combustion zone separated from the burner head

摘要

The head (2) has a twisting device (38) supplying twisted combustion air into a combustion-free mixing chamber (52) downstream to the twisting device within a burner pipe (22). Two fuel nozzles (8, 16) arranged downstream of the twisting device within the pipe supply unburnt fuel into the chamber to mix the unburnt fuel with the twisted combustion air. The twisting device has an area (48) downstream to an area (44) that comprises twisting elements (46) for twisting combustion air, where the area (48) guides the twisted combustion air separated from the combustion air into the area (44). An independent claim is also included for a method for single-stage combustion of fuel in a combustion chamber.
