NOZZLE FOR LOW PRESSURE FLASH TANKS FOR ORE SLURRY

摘要

A wear-resistant flash tank pressure let down nozzle for use in passing an o re slurry into an ore slurry flash tank to release steam from the slurry and reduce the pressure of the slurry. The nozzle has an expansion cone flaring toward the discharge end of the nozzle. The cross-sectional area of a choke section of the nozzle and the exit diameter of the expansion cone are select ed to establish a relationship between pressure upstream of the nozzle and pressure in the flash tank so that underflashing, overflashing, and shock waves inside the flash tank are minimized.
