THE UTILISATION OF PRODUCTS FROM THE FLUIDISED BED COMBUSTION OF COAL WASHERY WASTES

The fluidised bed combustion (fbc) process has been developed to the stage that both coarse rejects and tailings from coal washeries may be successfully combusted in a fbc pilot plant. During the combustion process excess heat is produced, and the products from the process - spent rejects and primary and secondary cyclone fines - are reduced in volume compared to the input materials. Preliminary research into the properties of the spent rejects and cyclone fines has been undertaken within the department of civil engineering of the University of Wollongong. A continuing programme is being undertaken to investigate and evaluate the potential uses of the fbc products, including the use of the products in stabilised and unstabilised forms in road construction; in concrete mixes either as an aggregate or as a pozzolan; and as an embankment material. The potential uses of the combusted products are compared, where appropriate, with the uses of the unburnt materials (A).
