Laser-based diagnostics for coal gasification instrumentation. [Coherent anti-Stokes Raman spectroscopy (CARS), laser induced breakdown spectroscopy (LIBS) and laser-induced fluorescence (LIF)]
In this program the investigators have investigated the suitability of a number of optical diagnostic techniques for nonintrusive real-time measurements of species concentrations and temperatures of coal gasification streams. They have identified and evaluated several promising techniques including coherent Raman spectroscopy, laser-induced breakdown spectroscopy, and laser-induced fluorescence. They emphasize that these are complementary, rather than competing, diagnostic technologies, as each can provide a different class of data for gasifier operation. The results of their gasifier field tests and supporting laboratory work on these diagnostic techniques have been summarized and recommendations for continued work on optical diagnostics for coal gasification streams are presented. 12 references, 17 figures.
