A DEVELOPOMENT OF ON-LINE TEMPERATURE MEASUREMENT INSTRUMENTATION FOR GASIFICATION PROCESS CONTROL

Description

This progress report covers continuing work to develop a temperature probe for a coal gasifier. A workable probe design requires finding answers to crucial questions involving the probe materials. We report on attempts to answer those questions. We designed, assembled, and tested a portable test fixture that can give relative quantitative data on the condition of phosphors. It needs a more-sensitive detector for optimum performance. We ordered an appropriate detector. A second experimental test of the survivability of thermographic phosphor in a high-pressure, high-temperature reducing environment showed no substantial deterioration of the phosphor. This very important result further confirmed the ... continued below

Description

This progress report covers continuing work to develop a temperature probe for a coal gasifier. A workable probe design requires finding answers to crucial questions involving the probe materials. We report on attempts to answer those questions. We designed, assembled, and tested a portable test fixture that can give relative quantitative data on the condition of phosphors. It needs a more-sensitive detector for optimum performance. We ordered an appropriate detector. A second experimental test of the survivability of thermographic phosphor in a high-pressure, high-temperature reducing environment showed no substantial deterioration of the phosphor. This very important result further confirmed the results reported last time. We arranged for one more test as evidence that there is no effect or, if there is, then the data will give us a deterioration rate. That third test is underway at the time of this report. We aligned and tested the prototype probe. It works as expected. The DOE/NETL arranged for a test bed to test the probe and the measurement system in a real environment. We visited the facility to learn what will be required to do the field test.
