Abstract: A device for generating soot particles with a reproducible and variable size distribution includes a combustion chamber (1), to which it is possible to supply fuel and oxidation gas and in which a flame may be formed, which is fed by the fuel and by the oxidation gas and which generates soot particles, and a soot removal conduit (3), which is coupled with the combustion chamber, in that, for example, it comprises an inlet from it, wherein the soot removal conduit in addition includes an inlet for a quenching gas. The combustion chamber and the soot removal conduit are part of a hollow space, which is capable of being decoupled from the ambient air in such a manner, that it is possible for it to be impinged by a pressure, which is different from the atmospheric pressure.

Abstract: The method, and device for carrying out the method, for producing soot with defined characteristics for measurement or calibration purposes, contains the method steps of supplying fuel gas and oxidation gas (1, 2) into a combustion chamber (4), bringing the fuel gas and oxidation gas to react in the combustion chamber (4), so that a flame (3) arises, setting flow conditions in the combustion chamber (4), so that a gas flow in the flame (3) runs in a non-turbulent manner, and supplying cooling and dilution gas (5) into the combustion chamber (4) downstream of the flame (3) with respect to the flow direction. A soot discharge conduit separate from the combustion chamber (4) becomes superfluous on account of the procedure according to the invention.
