1. method that is used for making the synthetic silica glass in the combustion chamber of muffle, wherein-forming gas stream, this gas stream contains the oxygenant and the transpirable gasiform silicon compound of fuel, chemistry, and this silicon compound is converted to SiO by flame hydrolysis and/or the oxygenant by chemistry 2Particle;

  • -SiO 2Particle deposition forms the quartz body of roller shape simultaneously to the depositional plane of target compound;

    -wherein the combustion chamber is limited by wall, and the combustion chamber has the pneumatic outlet of the gas inlet and the back of front in its front end and its rear end, and wherein said wall and opening are around longitudinal axis rotation symmetry, and the combustion chamber broadens backward from the gas inlet;

    With-wherein gas stream produces by at least three nozzles, comprises the nozzle of the central authorities that are used for the feed-in silicon compound that are arranged on longitudinal axis front end, and-with isolated first ring nozzle that is used for the feed-in oxygenant that is provided with one heart of central nozzle and-second ring nozzle that is used for feed-in fuel that is provided with equally with one heart, the diameter of this second ring nozzle be greater than first ring nozzle,It is characterized in that first nozzle has first circular clearance, second nozzle has second circular clearance, and the area of second circular clearance is 1;

    4 to 1;

    6.1 with the ratio of the area of first circular clearance.
