Abstract
The temperature of a metallurgical slurry in a heater vessel is accurately controlled by heating a first portion of the slurry in the heater vessel by contact with a heating medium such as steam, and by adding to the heater vessel controlled portions of a slurry at lower temperature. The lower temperature slurry may be added to the heater vessel in an intermittent or continuous manner, with addition of the lower temperature slurry being regulated by a valve, the operation of which is controlled by a control device which receives temperature information from one or more temperature sensors.
