1. An apparatus for producing of carbon black, comprising
a) a furnace reactor comprising
a first reaction zone for generating a hot flue gas stream and at least one line in flow connection with the first reaction zone for feeding an O2-containing gas stream to the first reaction zone and at least one line in flow connection with the first reaction zone for feeding a fuel stream comprising combustible material to the first reaction zone;
a second reaction zone for contacting the hot flue gas stream with carbon black feed stock, the second reaction zone being downstream of and in flow connection with the first reaction zone, and at least one line in flow connection with the second reaction zone for feeding carbon black feed stock to the second reaction zone; and
a third reaction zone for terminating a carbon black formation reaction, the third reaction zone being downstream of and in flow connection with the second reaction zone, the third reaction zone comprising means for quenching the carbon black formation reaction; and
b) an inert gas supply unit; and
c) at least one line connecting the inert gas supply unit to the reactor or to any of the feeding lines for feeding material to the reactor in order to feed an inert gas stream to the reactor,
wherein the inert gas supply unit is a storage unit, an air separation unit, or a supply line connecting an external inert gas production facility to the apparatus.
