Gasification Systems - Gasifier Optimization Main Area
Single-Crystal Sapphire Optical Fiber Sensor Instrumentation Virginia Polytechnic Institute
Project No.: DE-FC26-99FT40685
Phase I - The Photonics Laboratory at Virginia Tech has successfully developed a novel temperature sensor capable of operating at temperatures up to 1600 °C and in harsh conditions. The sensor uses single-crystal sapphire to make an optically-based measurement and will fulfill the need for the real-time monitoring of high temperatures created in gasification processes.
Phase II - Based on a successful Phase I laboratory demonstration of a Broadband Polarimetric Differential Interferometric (BPDI) temperature sensor, Virginia Tech's Phase II development objective is to further the development of the sensor for industrial use in slagging coal gasifiers. This will include ruggedizing the design of the sensor and creation of a suitable protective housing such that it can be placed into existing ports of coal gasifiers. The potential industrial use of the sensor will be determined through full-scale testing and development. The sensor design and fabrication has been completed and is undergoing testing. Overall performance and survivability of the sensor will be determined.
