Abstract (en)
[origin: EP2023041A1] The method involves injecting an air mass flow (5) and fuel (6) e.g. synthetic gas, into a premixing zone (2) of a premixing burner (1) for forming a potential hot gas backflow area. A fluid (15) e.g. inert gas, which does not contain fuel, is injected downstream towards a fuel injection into the premixing zone. The fluid is injected into the premixing zone along the surface area of the premising zone in a main flow direction (9). The fuel is injected into the premixing zone perpendicular to the main flow direction of the air mass flow. An independent claim is also included for a premixing burner comprising a premixing zone.
