Ash and pulverized coal deposition in combustors and gasifiers. Quarterly technical progress report, October 1--December 31, 1994
The general goal of this research is to provide a fundamental understanding of transport and deposition mechanisms of ash and pulverized coal particles in complex turbulent flow conditions in a coal-fired combustor or in a coal gasifier. The other main objective is to develop an accurate computational model for simulating motions of ash, pulverized coal, and soot particles in complex geometries of coal (gas turbine) combustors and gasifiers. Availability of these tool and knowledge base will be indispensable for making the environmentally acceptable coal energy system a reality. In the period of September 1, 1994 to December 31, 1994, progress was made in initiating the project. Particle transport and deposition processes in a circular duct and in a recirculating region are being analyzed. The experimental data for the mean velocity and turbulence intensity fields, as well as those obtained from the STARPIC-RATE code are used in these simulations. Experimental study of particle transport and deposition rate is also initiated.
