Computational Modeling of CO/CO2 Ratio Inside Single Char Particles during Pulverized Coal Combustion

A recently developed model was used to study the CO/CO2 ratio inside a burning pulverized coal particle, to better understand the effect of bulk gas composition on the equilibrium partial pressure of reduced metal species at the surface of ash inclusions. The motivation was to improve the ability to model submicrometer particle formation by ash vaporization, as a function of furnace conditions....

The fate of char-N at pulverized coal conditions

The fate of char-N (nitrogen removed from the coal matrix during char oxidation) has been widely studied at fluidized bed conditions. This work extends the study of char-N to pulverized coal conditions. Coal chars from five parent coals were prepared and burned in a laboratory-scale pulverized coal combustor in experiments designed to identify the parameters controlling the fate of char-N. The ...

Modeling of Mass Loss of Char Particles during Combustion and Interaction with Inert Material

The inspiration for this research was the numerical simulation of mass loss of char particles during its combustion in a CFB boiler. The mass loss was presented as the superposition of two separate processes i.e. combustion and surface erosion. The values obtained by the model and experimental data show a good level of conformity. INTODUCTION Until now many authors have attempted numerical simu...
