Show -17- Here, it has been suggested that the IFRF should become involved in research upon the fuel staging technique and/or substoichiometrically operated, slagging precombustors with calcium injection. These possibilities are presently under review. - The general programme of "near field studies" is now progressing well in terms of the aerodynamics of swirl burner and also in the field of .flame chemistry, viz. the sorbent studies. A possible extension in this general area relates on the firing of liquid fuels where, considering the fuel trends, e.g. "heavy" • petroleum residues and coal in water slurries, a better understanding of the process of atomization and atomizer design is essential. - Coal characterisation studies are already planned within the present programme and may be extended to include the problem characterisation of coal in water slurries in terms of slurry atomizability. These points by no means exhaust all the possible avenues for future research open to the IFRF. Other suggestions [ 17 ] made include for example, a review of the possibility of research in fluid bed combustion. Nevertheless, they can form a basis of discussions on future programmes of interest to the American Flame Research Committee. |
