Abstract: The soot generator comprises a combustion chamber (11), in which fuel (16) can be burnt with an oxidizing agent (21) in at least one soot particle-producing flame (33), a fuel feed line (15) for supplying fuel (16) to the combustion chamber (11), a soot removal line (36), which is connected to the combustion chamber (11), into which soot removal line quenching gas (38) can be conducted and out of which soot particles can be transported, and a heating device (25-31) for heating the fuel feed line (15) at at least one heating location (15a).

Abstract: A burner for producing carbon black, includes a combustion chamber which can be supplied with fuel gas and an oxidizing gas in such a way that a diffusion flame producing carbon black particles is generated in the combustion chamber. The burner is also provided with a carbon-black discharge line. Carbon black formed in the combustion chamber can be discharged via an opening in the combustion chamber which feeds into the carbon-black discharge line. The discharge line is also provided with an opening through which an extinguishing gas can be supplied to the carbon-line. The burner permits the stable and reproducible production of carbon black particles which present well defined chemical and physical characteristics.
