Char particle fragmentation and its effect on unburned carbon during pulverized coal combustion. Quarterly report, July 1, 1993--September 30, 1993
The overall objectives of the project are: (1) to correlate char particle porosity with fragmentation phenomena, (2) to determine if mineral matter in the coal affects fragmentation patterns, and (3) to relate the effects of fragmentation events to unburned carbon in ash. The knowledge obtained during the course of this project will be used to predict accurately the overall mass loss rates of coals based on the mineral content and porosity of their chars. The work will provide a means of assessing reasons for unburned carbon in the ash of coal fired boilers and furnaces. The project is divided into four research tasks. Specific objectives associated with each task are as follows: Task 1--production and characterization of synthetic chars; Task 2--baseline char combustion experiments; Task 3--char fragmentation studies; and Task 4--fragmentation modeling. Results from the first two tasks are presented.
