  • Carbon black refractory system
    Patent number: 5817287
    Abstract: A refractory system for a reactor for producing carbon black. The system comprises a plurality of refractory bricks having an elongate axis arranged to provide at least one path through which a gas can flow. The path extends substantially perpendicular to the elongate axis and a plurality of the refractory bricks present a cross-sectional aspect to the gas flow which decreases, in the downstream direction, from a maximum aspect to reduce dead regions in gas flow adjacent the refractory bricks.
