Combustion inorganic transformations
The overall goal of the project is to develop a unified picture of the physical and chemical changes that occur in coal inorganic matter during combustion. The research is centered on two main tasks. Task 3.2A deals with the use of laser-induced fluorescence spectroscopy (LIFS) to study the release of sodium from various model compounds and coal during combustion in a flame. The vaporized or released sodium is considered to be an important factor in the formation of ash fouling deposits in full-scale utility boilers. Task 3.2B will study changes in the morphology and chemical associations of inorganic components in coals during combustion in a drop-tube furnace designed to simulate the time-temperature profile of a pulverized coal-fired utility boiler. Results are described. 18 refs., 51 figs., 28 tabs.
