Ash and pulverized coal deposition in combustors and gasifiers. Quarterly technical progress report, April 1, 1996--June 30, 1996

PDF Version Also Available for Download.

Description

The general goal of this project is to provide a fundamental understanding of deposition processes of flyash and pulverized coal particles in coal combustors and coal gasifiers. In the period of April 1 to June 30, 1996, further research progress was made. The computational model for simulating particle motions in turbulent flows was applied to the dispersion and deposition analysis. The study of particle transport and deposition in a circular duct was completed and the major findings are summarized. A detailed model for particle resuspension process in a gas flow is developed. The new model accounts for the surface adhesion, ... continued below

The computational model for simulating particle motions in turbulent flows was applied to the dispersion and deposition analysis. The study of particle transport and deposition in a circular duct was completed and the major findings are summarized. A detailed model for particle resuspension process in a gas flow is developed. The new model accounts for the surface adhesion, surface roughness, as well as the structure of near wall turbulent flows. The model also accounts for all the relevant hydrodynamic forces and torques exerted on the particle attached to a surface. Progress was also made in the experimental study of glass fiber transport and deposition in the aerosol wind tunnel.
