1785 On the relevance of surface growth in soot formation in premixed flames2000surface growth; soot formation; premixed flames; surface growth mechanisims; particle mass accumulationThe role of surface growth mechanisms in particle mass accumulation was investigated in rich, premixed, ethylene/air flames from non-sooting to moderately sooting conditions using in situ optical diagnostics and predictions from a detailed chemical kinetic model. Particles formed just after the flam...
1786 On trimodal particle size distributions in fly ash from pulverized-coal combustion2002trimordal particle size distributions; fly ash; pulverized-coal combustion; fine particles; PMCombustion-generated fine particles, defined as those with aerodynamic diameters less than 2.5 lm, have come under increased regulatory scrutiny because of suspected links to adverse human health effects. Whereas classical theories regarding coal combustion suggest that mechanisms of ash vaporizatio...
1787 On-line, mass spectrometric determination of ammonia from oil shale pyrolysis using isobutane chemical ionization1988-03Ammonia is the predominant nitrogen-containing species formed during the pyrolysis of oil shale. An on-line method of determining ammonia was developed to study kinetics and chemistry of formation and evolution. While fragmentation of water interferes with electron ionization mass spectrometry, chem...
