Title: Kinetic modeling of the formation and growth of inorganic nano-particles during pulverized coal char combustion in O₂/N₂ and O₂/CO₂ atmospheres

Abstract

In this formation of nano-particles during coal char combustion, the vaporization of inorganic components in char and the subsequent homogeneous particle nucleation, heterogeneous condensation, coagulation, and coalescence play decisive roles. Furthermore, conventional measurements cannot provide detailed information on the dynamics of nano-particle formation and evolution, In this study, a sophisticated intrinsic char kinetics model that considers ash effects (including ash film formation, ash dilution, and ash vaporization acting in tandem), both oxidation and gasification by CO₂ and H₂O, homogeneous particle nucleation, heterogeneous vapor condensation, coagulation, and and coalescence mechanisms is developed and used to compare the temporal evolution of the number and size of nano-particles during coal char particle combustion as a function of char particle size, ash content, and oxygen content in O₂/N₂ and O₂/CO₂ atmospheres .

Suppression of fine ash formation in pulverized coal flames. Quarterly technical progress report No. 2, January 1, 1993--March 31, 1993

Technical Report Kramlich, J C ; Hoffman, D A ; Butcher, E K

The second major ash producing mechanism is the generation of a submicron aerosol through a vaporization/condensation mechanism. When the ash size distribution is plotted in terms of number density, the submicron mode generally peaks at about 0. 1 {mu}m. When plotted in terms of mass, this mode is sometimes distinct from the residual ash mode, and sometimes merged into it. During diffusion-limited char combustion, the interior of the particle becomes hot and fuel-rich. The non-volatile oxides (e.g., Al{sub 2}O{sub 3}, SiO{sub 2}, MgO, CaO, Fe{sub 2}O{sub 3}) can be reduced to more volatile suboxides and elements, and partially vaporized. Thesemore »« less

Evolution of char chemistry, crystallinity, and ultrafine structure during pulverized-coal combustion

Conference Davis, K A ; Hurt, R H ; Yang, N Y.C. ; ... - Combustion and Flame; (United States)

The carbonaceous structure of partially reacted char samples, generated by direct injection of pulverized coal into a laboratory entrained flow reactor, was characterized by four techniques: elemental analysis, carbon dioxide vapor adsorption, X-ray diffraction, and fringe-imaging using high-resolution transmission electron microscopy. It is observed that the early stages of heterogeneous oxidation proceed in parallel with the latter stages of carbonization, leading to preferential loss of hydrogen, a reduction in surface area, and the development of crystalline order. Typical combustion times and peak temperatures are insufficient to bring about true (three dimensional) graphitization for most coals, but rather, lead to themore »« less
Combustion fume structure and dynamics. Semiannual report, August 16, 1993--February 15, 1994

Technical Report Flagan, R C

During pulverized coal combustion, a fume of submicron particles is formed from the mineral matter in the parent coal. Studies of the variation in chemical composition with particle size have revealed that much of the submicron fume is formed from volatilized coal ash. The formation and evolution of the ash fume is governed by homogeneous nucleation, condensation, and coagulation. Vapors of refractory species nucleate relatively early in the combustion process. Coagulation of those fine particles results in a size distribution that is approximately log normal. More volatile species remain in the gas phase until after the nucleation has taken place.more »« less
