Abstract (en)
[origin: EP1030109A1] Liquid and/or gas-form fuel is injected into a combustion chamber by a fuel lance (10), involving a first guide tube (23) for the radial injection of fuel out of a liquid fuel channel (17) into the combustion chamber. The guide tube runs outwards through a gas channel (15) and an air channel (13). A second guide tube (21) runs outwards in a radial direction from the gas channel through the air channel. The second guide tube concentrically encloses the first guide tube spaced from it. Both guide tubes issue in the area of a lance cover (12) aperture (22) so that the liquid fuel emerging from the first guide tube forms a plain jet and the fuel jets from both tubes are surrounded cover-wise by air flowing from the air channel.
