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

PDF Version Also Available for Download.

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 received and studied new samples of an important thermographic phosphor, YAG:Dy. We studied the brightness as a function of dopant concentration and the relative brightnesses of the pertinent thermographic emission lines, both with respect to each other and among the phosphors. With the previously reported failure of the binder method for coatings, we are setting up a plasma-spray facility in cooperation with ... continued below

With the previously reported failure of the binder method for coatings, we are setting up a plasma-spray facility in cooperation with a subcontractor. We have been forming a network of people and organizations that may help us with various aspects of the problems at hand. This period, we approached a company with commercially successful probes, met with Tennessee Valley Authority staff (codes and coatings), and added a new faculty member to the team with materials expertise.
