Vacuum circulation degassing system with pilot burner. The present invention relates to a vacuum circulating degassing plant (1) comprising a vacuum container (2) with a dome (3) that can be connected to a vacuum pump, and two immersion tubes (4). which can be immersed in the melting (6) of a coordinated pan (5) as well as with a blow lance (7) which can be positioned displaceable in the vacuum container (2), with combined oxygen blowing and Since a pilot burner (11) is coordinated to the blow lance (7), a solution must be achieved to achieve increased availability of the blow lance and the installation. This is achieved by the fact that the pilot burner (11) is arranged in an ignition chamber (9), in which it can be moved, in particular, by displacing the blow lance (7) to various relative positions. relative to the blow boom (7).
