Title: Real-Time Temperature Measurement in a Vacuum Degasser Using Optical Pyrometry

Abstract

The objective of the research was the development of a fiber-coupled, optical pyrometer for continuous temperature measurement in a vacuum degasser that reduces process time, enhances process control, and eliminates manual or robot-operated thermocouples. Through the live testing performed at US Steel's Edgar Thompson Works, the challenges associated with making optical temperature measurements in a vacuum chamber were identified. As a result of these challenges it was determined that continuous temperature monitoring in RH-type degassers was not a viable alternative to standard immersion thermocouples. The project was not successful.

  • A fiber optic-based fluorometer system is described that uses a pulsed laser to induce fluorescence and a time-gated linear photodiode array coupled to a spectrograph for rapid measurement of fluorescence emission spectra and fluorescence decay times. Data is presented from studies conducted in San Diego Bay where the system has been used for real-time in situ measurements of temporal and spatial variability of petroleum hydrocarbons in seawater. Results show that the optical fiber fluorometer system is capable of direct quantification of low level (parts-per-billion diesel fuel marine equivalent) concentrations of petroleum hydrocarbons. Analysis times for measurement of complete fluorescence emissionmore » spectra are fast (tens of milli-seconds) and compare with the temporal response characteristics for temperature and conductivity sensors that are used for measuring standard physical hydrographic parameters. Results obtained with the fiber optic fluorometer system during a mapping study in San Diego Bay show good correlation with GC-MS analysis of total polycyclic aromatic hydrocarbons (PAHs) measured on discrete samples collected during the study.« less
  • This report presents the experience gained by field testing an infrared optical pyrometer as a Turbine Blade Temperature Measurement System (TBTMS). This system was designed, built, and tested to make diagnostic measurements on an operating gas turbine at the T.H. Wharton Station of Houston Lighting and Power. The TBTMS is comprised of a probe assembly, an optical conduit, a detector, and a signal processor. The system senses thermal radiation from the turbine blades and transforms that signal into a real time value indicating the blade metal surface temperature. The information supplied by the TBTMS was recorded by a data acquisitionmore » system that also gathered information about the operation and performance of the engine. The information from the TBTMS was correlated with the critical operating parameters of the engine over a span of approximately 7000 hours. Initial performance of the TBTMS was satisfactory, and the configuration proved reasonably durable, demonstrating the value of such a probe for diagnosing engine conditions. Most notably, the pyrometer detected several blades that were consistently hotter than adjacent blades; such conditions could lead to shorter blade life. The report discusses blade temperature profiles and math models for predicting the durability of the blades. Recommendations were included which addressed design improvements for future TBTMS. 56 figs.« less
  • This report covers work performed on Contract AT(30-1)-1316 between the Brown Instruments Division of the Minneapolis-Honeywell Regulator Company and the New York Operations Office of the Atomic Energy Commission. The emittance of salt-coated uranium (a eutectic mixture of lithium and potassium carbonates) was found to be about 0.86 between the temperatures of 900 deg F and 1200 deg F. The emittance of uranium oxide (U3O8) was found to be about 0.82; the emittance of the salt mixture was 0.9; and the emissivity of uranium metal between 200 deg F and 600 deg F was 0.15. A holder and housing formore » the Brown Miniature Radiamatic Radiation Pyrometer was developed which was flexible and could be used to advantage measuring the temperature of uranium ingots and bars during the rolling operation. A number of these units were fabricated for the Feed Materials Center at Fernald, Ohio. A calibration panel was designed and built which permitted easy calibration of the Radiamatic assemblies. This panel contained a blackbody furnace as a radiation reference source. A considerable amount of time was spent during the spring of 1952 working at the experimental rollings held at several steel mills.« less
