The overall objective of Phase II is the development of an FT-IR instrument for the rapid and automated determination of char, soot, ash and gas temperatures and concentrations, and char and ash particle sizes in practical combustion devices. The technique employs measurements made at more than 1000 frequencies in the mid IR (400-6500/cm). Both emission and transmission measurements are made for temperature determinations, and the technique is referred to as the E/T technique. The large amount of information in the complete spectrum permits the elimination of some of the assumptions normally made in color-temperature measurements and permits monitoring of several phases. During the program, these capabilities of the FT-IR were demonstrated in the laboratory. In addition, an instrument capable of being operated in the more severe environment of process monitoring was selected and modified for the E/T measurements. Two successful field tests were made of the instrument demonstrating on-line and in-situ capabilities.
