A large research effort at the Morgantown Energy Technology Center to develop instrumentation for process steam characterization in support of both gasification and fluidized bed combustion technology development is discussed. For measurement of particles in the process stream, a non-intrusive laser-based optical particle monitor was developed and is being field tested. This instrument, based on the use of laser beam interference patterns and light scattering, can operate in either of two particle size ranges. Using the light scatteirng mode, particles in the 0.3 to 3 micron range can be quantized or, using interference patterns, sizes of 3 to 30 microns can be determined. A unique mass spectrometer was also developed for the analysis of particles in a gas stream. The laser device allows real time continuous monitoring of the gas composition from fluidized bed combustion of coal. The spectrometer system is able to determine concentrations of nitrogen, carbon monoxide, and hydrogen sulfide. (JMT)
