The overall objectives of this project is an intensive effort on the application of laser to the microscopic structure and thermochemical kinetic studies of coal particles pyrolysis, char combustion and ash transformation at combustion level that fluxes in a laser beam. Research emphasis in FY91 is placed on setup and calibration of the laser pyrolysis system, preparation and mass loss studies of Beulah lignite and subbituminous coals. The task is therefore divided into three subtasks. 4 figs., 2 tabs.
