Characterization and Combustion of SRC II Fuel Oil

Abstract

This paper deals with an experimental evaluation of the combustion properties of solvent refined coal II fuel oil. The purpose was to identify problems, if any, associated with handling, storing, pumping, and burning SRC fuel oil. Detailed fuels characterizations were performed and compared to petroleum distillate products. Laboratory fuel analyses and combustion tests were performed with SRC fuel oil, No. 2 fuel oil, and No. 5 fuel oil. Four B&W atomizers were tested and two B&W oil burners were utilized. The laboratory fuel analyses indicated that in most respects this SRC fuel oil sample behaved similarly to No. 2 fuel oil. The combustion tests confirmed that expectation. The one identified problem was relatively high concentrations of fuel-bound nitrogen and, consequently NOx emissions were relatively high. It was concluded that SRC fuel oil may require the application of NOx combustion control techniques.
