  • The topical report summarizes the work performed during the first phase of a three phase contract funded by GRI. The objective of the program is to develop an improved gas sensor system for accurate 'on-line' monitoring of combustion species aimed to improve the efficiency of gas-fired combustion systems. Phase I of the program was the feasibility analysis of the proposed fiber optic multi-gas sensor. The analysis included: (1) a comprehensive literature search of research being performed in the areas of combustion diagnostics and fiber optic sensors, (2) a gas sensor vendor survey to evaluate the potential use of commercially availablemore » gas sensors for 'on-line' stack gas analysis, and (3) an optical fiber evaluation, including temperature testing of selected fiber samples and evaluation of fiber optic materials which are currently under development. Phase II of the program will entail fabrication and testing of a proof-of-concept fiber optic sensor system.« less
  • The development of thin film temperature sensors is discussed. The technology for sputtering 2 micron thin film platinum versus platinum 10 percent rhodium thermocouples on alumina forming coatings was improved and extended to applications on actual turbine blades. Good adherence was found to depend upon achieving a proper morphology of the alumina surface. Problems of adapting fabrication procedures to turbine blades were uncovered, and improvements were recommended. Testing at 1250 K at one atmosphere pressure was then extended to a higher Mach No. (0.5) in combustor flow for 60 hours and 71 thermal cycles. The mean time to failure wasmore » 47 hours accumulated during 1 hour exposures in the combustor. Calibration drift was about 0.1 percent per hour, attributable to oxidation of the rhodium in the thin films. An increase in film thickness and application of a protective overcoat are recommended to reduce drift in actual engine testing.« less
  • The pace and breadth of fiber optic sensor research and development are enormous. This study identifies potential applications of fiber optic sensors in power systems, evaluates the present technology, suggests development of sensors for applications, and identifies areas of research. Among the numerous applications studied, several were suggested for additional research. 10 refs.
  • The overall objective of our DOE-Ocean Margins Programs grant is to develop a pCO[sub 2] sensor for long-term monitoring of pCO[sub 2] in the ocean margins and to establish a proving ground for the development of other chemical sensors for characterizing the carbon cycle in these regions. We have succeeded in keeping with the approximate timeline outlined in the original proposal, which, for year 1 included the following objectives: Continue sensor optimization, test response characteristics (reagent and sample flow rates, temperature), introduce position sensitive photodiode and photodiode array spectrophotometers and evaluate, develop reliable and reproducible fabrication techniques, develop sensor basedmore » on preliminary studies optimized for field measurements (minimize size and power requirements), test long-term stability of the sensor in the laboratory, determine susceptibility to fouling and corrosion. This work is summarized below along with a brief review of the sensor's operating principle.« less
