This paper covers combustion performance of EDS fuel oil blends, with primary emphasis on the emissions of polynuclear aromatics (PNA). Previous testing of EDS fuel oil blends and other coal-derived fuel oil blends has shown that emissions of particulate and smoke are lower with coal-derived fuel oils than from the combustion of petroleum-derived fuel oils. NO /SUB x/ emissions tend to be higher due to the higher fuel-nitrogen levels of coal-derived fuel oils. However, it appears, based on small scale lab tests and limited commercial tests that staged combustion should allow NO /SUB x/ emissions standards for coal-derived fuel oils to be met. One environmental concern that had not been addressed in these tests is the emissions of PNA. This is a potential concern due to the highly aromatic nature of coal-derived fuel oils. The work reported here was carried out in two phases. The first phase was conducted in laboratory test boilers to determine the relative PNA emissions from a variety of EDS and petroleum fuels. When PNA emissions from EDS fuel oils were found to be higher than from petroleum fuel oil combustion, the effects of adjusting combustion parameters, such as nozzle design or atomizing air pressure, were investigated in the laboratory units. The second phase testing was conducted in a commercial boiler to determine the effect of unit size on PNA emissions. This testing was made possible by the start-up and operation of the Exxon Coal Liquefaction Pilot Plant (ECLP) which has a throughput of 250 tons per day and can produce approximately 600 barrels per day of liquid product. Prior to this unit, the quantity of fuel oil available would not allow such large scale testing.
