Fuel nozzle

摘要

The fuel nozzle has a nozzle tube (2) connected to a fuel feed line for feeding fuel i.e. synthetic gas, to the tube. The tube injects the fuel from a nozzle outlet opening (10) to an annular air stream (8) surrounding the fuel nozzle. A nozzle tube section (4) extends up to the opening and is designed in a floral pattern (6) such that the fuel is coaxially injected into the air stream. The opening has a closed conical floral hub that includes grooves and tapers in a flow direction. The hub is connected with a pipe for supply of high-calorific value fuel.
