Combustion characterization of coal fines recovered from the handling plant. Quarterly technical progress report number 6, January 1--March 31, 1996
The main goal of this research project is to evaluate the combustion characteristics of the slurry fuels prepared from the recovered coal fines and plant coal fines. A specific study was completed which collected data on combustion behavior, flame stability, ash behavior, emissions of SO{sub 2} and NO{sub x}, and particulate in a well insulated laboratory scale furnace. In addition, the residence time and temperature history of the burning particles are similar to that of the utility boiler furnace at 834,330 Btu/hr input at an average of 15% excess air. The slurry fuel was prepared at 53.5% solids to match the generic slurry properties. The coal blend was prepared using a mixture of 15% wet milled pond fines and 85% plant fines. Combustion characteristics of the slurry fuels were determined at three different firing rates: 834,330 Btu/hr, 669,488 Btu/hr and 508,215 Btu/hr. Finally a comparison of the results will be developed for determining the advantages of coal-water slurry fuel over the plant blend form.
