Title: AUTOCLAVE SYSTEM AND METHOD
Abstract:
An autoclave system comprises an autoclave vessel (210), for performing a leaching operation on sacrificial ceramic cores (not shown) and a storage vessel (220) for containing caustic leaching fluid (230). Interposed in a fluid flow path between the vessel 210 and the tank (220) is a heat exchange unit (240), comprising a body (250) containing a thermal exchange medium, in the form of water (260), and first and second thermal exchange conduits represented at (270) and (280). A thermal exchange medium inlet pipe (290a) and a thermal exchange medium outlet pipe (290b) are provided to the body so that the medium (260) can be replenished, preferably substantially continuously, to optimize thermal transfer efficiency.
