“…Results to date have indicated that the ability to burn these fuels with minimal soot and NO emissions will require the development of staged-combust ion systems. It has been shown that the sooting limits for aromatic fuels occur at mixture conditions at which hydrocarbons are first observed in the combustion products, and that the minimization of fuel nitrogen conversion requires operating at the higher fuel-air ratio prior to the breakthrough point (17,18). The results have been obtained under rather idealized conditions, i.e., either in a jet-stirred combustor or in a staged-combustion facility designed to control the flow and mixing characteristics.…”

The need to conserve energy and to control pollu tant emissions while at the same time introducing a new generation of fuels derived from coal, oil shale and tar sands is introducing severe re quirements on the design and retrofit of combustion equipment.The different chemical and physical properties of these synthetic fuels leads to substantial differences in their combustion characteristics and emissions. In particular there is the potential for increased soot formation, higher ΝO x emissions, increased and modified radiation and heat-load distribution, and increased contamination and fouling of combustion and heat transfer surfaces when compared to more conven tional fuels. Staged combustion techniques to simultaneously control ΝO x and soot production are being developed. However, various burner, boiler and furnace configurations are involved in practical applications and they each have different aerodynamic flow patterns and turbulence character istics.These flow field characteristics couple with the fuel physical and chemical properties in controlling the efficiency, emissions and fuel flexibility characteristics of practical systems. The U. S. Department of Energy, Advanced Research & Technology Development Program in Direct Utiliza tion, AR&TD (DU), is providing the scientific and technical information for improved, expanded, and accelerated utilization of synthetic fuels in the generic utility and industrial market sectors. In the present paper, we review the current under standing of synfuel combustion, and present an overview of the AR&TD (DU) program.
