Show -16- near field aerodynamics of swirl burners, and the formulation of a predictive tool for use in burner design. This programme was commenced in 1983 with the design and construction of the required experimental facility as shown in figure 14. At the time of writing, the first phase concerning flow visualisation is rearing completion. In the present planning the Research Report will be availablerto IFRF Members at the end of this year. FUTURE TRENDS The IFRF reviews the long term technical objectives of its members every three yearsu This process is presently in progress using as its basis, a review of future combustion problems as envisaged by the Superintendant of Research [ 17 ]. It is therefore too premature to be specific on future trends, as the process of feed-back from the members of the IFRE will not be completed before the end of 1984. However, it is clear from the progress made so far in the 1983-1985 research programme, I that if the same general themes remain acceptable to the IFRF members then three points can made: - Concerning the question of pollutant emissions control from flames, the research has shown that the techniques of air staged combustion and sorbent injection may be combined to produce a low NO /SO combustion system, pollutant control . . . . . x 2 but with limitation concerning the achievable levels, particularly with the maintenance of acceptable combustjion performance. The development of full scale techology is well advanced for air staged combustion and is progressing to the demonstration stage for sorbent injection. However, trends In some European pollutant emission control legislation are sich that flue gas cleaning both for NO and x SO will ultimately be necessary. Thus a question to be considered is that of "advanced" in-flame control techniques particularly for m e retrofit market. |
