Abstract (en)
[origin: EP0864812A2] The burner has a burner pipe and an end opening. The front part of the burner part contains a truncated cone-shaped inner pipe (2) containing a coaxial nozzle pipe (7) with fuel inlet. An ignition electrode is positioned in front of the pressure pulveriser nozzle (5). The burner pipe (1), inner pipe and nozzle pipe through which air flows have at least one rear air inlet hole and at least one front air outlet hole. Between the nozzle pipe and inner pipe is a further swirl generator. The swirl currents in the nozzle and inner pies are supercritical and run in the same rotary direction, while the air flow between the inner and burner pipes is not subject to swirling.
