<p>An apparatus for producing carbon black which has a first reaction zone (1) for receiving and burning an oxygen-containing gas and a fuel to form a burned gas stream, a second reaction zone (2), which is located downstream from the first reaction zone and has a port receiving a raw material hydrocarbon and feeding it to the burned gas stream, for reacting the raw material hydrocarbon to form a carbon black, and a third reaction zone (3) located downstream from the first reaction zone for terminating the above reaction, characterized in that a fuel receiving port (5) and a port (6) for receiving the oxygen-containing gas have their openings which are independently located apart from each other in the same side of a reacting furnace. The apparatus not only can produce a carbon black having a reduced particle diameter and a reduced distribution of an agglomerate diameter, with good efficiency, but also allows the suppression of damage of a refractory employed in the wall of the above reaction furnace, the perfect combustion of a fuel at an air ratio near to 1 in combination with a high burning temperature, and the suppression of emission of NOx.</p> |
