Book excerpt: As part of the U.S. Department of Energy (DOE) Office of Industrial Technologies (OIT) Industries of the Future (IOF) Forest Products research program, two different laser diagnostic techniques have been implemented in pulp mill recovery boilers to provide important information on entrained particles. One technique, based on single-particle scattering of a low-power, continuous-wave (cw) laser source, measures the velocity, concentration, and size distribution of particles within the furnace flow, over a predetermined range of particle sizes. For application to recovery boilers, this technique was designed to measure the range of particle sizes known as intermediate size particles (ISPs), roughly from 2-100 {micro}m in diameter. The other diagnostic technique, known as laser-induced breakdown spectroscopy (LIBS), uses a pulsed, high-power laser beam to create a localized plasma spark in the flow, allowing the measurement of the elemental composition of the entrained particles. This technique is most sensitive for particles less than 10 {micro}m in diameter. Implementing these laser diagnostic techniques in recovery boilers proved to be challenging. For the particle scattering measurement, the use of a narrow aperture for measurement of the forward scattered light was postulated and later confirmed to be effective in minimizing background signals associated with the dense sodium fume in the boilers. For the LIBS measurement, a new water-jacketed optics probe was implemented to allow for measurements with an insertion depth of up to two meters in the furnace. Fume particle deposition on the exposed optics at the end of the LIBS probe was problematic but improved with a redesign of the probe geometry and purge flow. Both diagnostic techniques were employed at two representative recovery boilers. The particle scattering diagnostic demonstrated similar trends in mean ISP concentration, ISP size distribution, and temporal variation of ISP concentration at the two boilers. The LIBS measurements showed the presence of a number of major chemical components as well as trace metal elements in the entrained particles.

Available in PDF, EPUB and Kindle. Book excerpt: Studying turbulent combustion at the fundamental level is a primary requirement to construct robust, accurate, efficient models to predict the performance of complex combustion systems. Laser based diagnostics offer significant advantage of probing multiple facets of the combustion processes simultaneously and are capable of providing quantitative information of the highly coupled phenomenon. Design of a vitiated co-flow burner is presented for laser diagnostics of turbulent flames. A foundation was laid to be able to perform Rayleigh scattering, Coherent Ani-Stokes Raman Spectroscopy, Heterodyne velocimetry and Particle scattering. Experiment facilities were developed and tests were performed for feasibility, and performance of test equipment. The present work focused on developing facilities for combined diagnostics of, temperature, species, concentration and velocity measurement. Machine vision cameras were studied for their performance with Rayleigh scattering for temperature, high resolution spectrometer is put to test to resolve rotational/vibrational bands from chemiluminesence for species concentration. An optical design for Narrowband CARS is presented. An experimental setup for multiphase turbulent flow is presented and methods were developed for image analysis in a multiphase turbulent flow. An experimental setup for simultaneous measurement of gas species concentration, particle concentration and particle velocity is presented. The final section discusses analysis of diode lasers and optics to perform seedless Laser Heterodyne Velocimetry. The current work also discusses some of the common problems and solutions for laboratory experiments using laser diagnostics.
