Abstract
An improved arrangement for feeding a cool liquid into a pressure vessel and mixing the fed liquid with hot liquid contained therein includes a flow-shielding ejector thermal sleeve disposed partially within an inlet nozzle and surrounding a supply line through which the main feed flow is conducted to a sparger outlet port in the vessel. The sleeve is spaced radially inwardly from the inner surface of the nozzle to define a generally annular flow-through space therebetween. Cool leakage liquid flow is confined within the sleeve and ejected by the main feed flow from an ejector chamber formed around the port by a downstream portion of the sleeve. The ejective action of the main flow exiting the port additionally draws an insulating flow of hot liquid from the vessel sequentially upstream through the flow-through space, into the interior of the upstream portion of the sleeve, and downstream with the confined cool leakage flow, thereby substantially reducing cracking of the nozzle.
