Description
The introduction of more stringent environmental and occupational health and safety regulations have instigated efforts to reduce the amount of dust generated during loading of ships with dusty bulk materials. An initial study was undertaken to investigate possible methods to reduce dust emissions from wheat loading operations at the Port of Newcastle. Details of this study are contained in an industrial report by Krull [I] and articles by Wheeler et al. [2, 31. In summary, a number of alternative loading chute configurations and delivery chute profiles were examined in a pilot-scale test facility, which showed that it was not beneficial to decelerate the product stream in an effort to keep the relative velocity of the air stream over the grain below the minimum pickup velocity. Instead, it was found that concentrating the product stream and keeping the product velocity high was more beneficial in reducing dust emissions. Experimental results showed a 50% dust reduction was possible and was subsequently achieved at the grain loading terminal. Further studies have since been conducted for Finders Ports in Port Adelaide, Australia to examine if the same approach could be used for loading ilmenite onto ships. Experimental results conducted in the pilot-scale test facility using the same chute configuration as used for wheat indicate a potential dust reduction of approximately 80%. For both the investigated ship loading operations, similar constraints on the implementation of dust reducing methods were imposed as follows: Required modifications to the ship loaders must be undertaken in a short period of time and if possible not involve any significant structural work to the ship loader. Ability to retrofit to the existing booms of the ship loaders. Existing filling levels of ships were to be maintained and the ship loader must be able to load grain underneath the decking on the ship's cargo hold. Due to strict export quality requirements no additives, including water, were to be used as dust suppression agents.
