<p>A refractory system for a reactor for producing carbon black. The syste m comprises a plurality of refractory bricks having an elongate axis arranged to provide at least on 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.</p> |
