Input assembly for high-temperature chemical reactor

摘要

A feed input assembly 2 for a high-temperature chemical reactor 4 includes a feed tube 6 having a feed inlet opening 8 and a feed-discharge opening 12. A cooling jacket 14 surrounds a length of the feed tube 6 extending from the feed-discharge opening 12. The cooling jacket 14 has an inlet 22 and an outlet 24 for respectively receiving and discharging a coolant. A coolant channel 17 is formed by a space between the cooling jacket 14 and the feed tube 6. The input assembly also includes flow-directing conduit means 32 for directing a flow of coolant from the inlet 22 of the cooling jacket 14 against inner wall portions of the feed tube 6 and cooling jacket 14 adjacent the feed-discharge opening 12.
