Effect of Flame Temperature and Fuel Composition on Sooting Tendency in a Research Combustor.
Abstract
Several fuel blends containing alkyl benzenes, methyl naphthalenes, tetralin and Indene were prepared with hydrogen contents ranging from 11.5 to 14.2 percent. The effects of burner inlet conditions on the sooting tendency of the test fuels were measured in a Phillips 2-inch diameter cylindrical combustor capable of inlet pressures and temperatures up to 1.6 MPa and 1030K, respectively. Both flame radiation and opacity measurements were used to determine the soot formed in the primary zone of the burner. Flame temperature was measured by the Kurlbaum method. Combustion efficiency and fuel/air ratio were determined from gaseous emissions. A sensitivity of sooting tendency to H/C ratio was determined from the correlation of flame radiation intensity with H/C ratio. This sensitivity varied significantly with operating parameters such as burner inlet temperature and reference velocity. The effects of polycyclic aromatics were determined by comparing the sensitivity to H/C ratio of fuels containing alkyl naphthalenes and tetralin to that of the fuels blended with alkyl benzenes. The increased sooting tendency of fuels containing alkyl naphthalenes and tetralin was most strongly dependent on the fuel/air ratio and the reference velocity.
