Peirce-Smith Converter Hood Improvements At BHP Copper

Several improvements in converter equipment and operation at BHP Copper have reduced the converter cycle time as necessitated by an increase in flash furnace output. The resulting higher intensity performance of the Peirce-Smith Converters has had a major impact on the dust handling and off-gas cleaning systems. This paper describes work carried out on the design of a new converter hood with particular reference to the thermal analysis and hood performance aspects. Changes in converter cycle time and campaign life as result of the process and equipment improvements are discussed in a separate paper.
