Operation of the PDU centered on testing the gasifier to evaluate performance with coke breeze and char derived from coal using oxygen and steam as the gasification media. However, since suitable chars were not available, direct coal feed to the gasifier was used. Four tests were run, TP-018-1 through -4, and operating summaries and test results are described. The operating results for Test TP-018-1 are summarized, with additional comparative studies showing the effects of air tube diameter changes on product gas characteristics, fines elutriation and axial temperature profiles from the results of TP-018-1 and TP-015-1. Test TP-018-2 was the first gasifier test to be run with oxygen. Total time for the test exceeded 180 hours, with 50 hours of operation using Pittsburgh seam coal as feedstock. Product gas higher heating values on a dry basis ranged from 120 Btu/scf for coke breeze to 260 Btu/scf for Pittsburgh coal. As part of the overall test objectives, effort was devoted to increasing ash content in the withdrawal stream, with the results that in TP-018-4 concentration was increased from 30 percent to 80 percent. An experimental test grid designed to show the effect of increased oxygen flow on reactor temperatures and heating values with the highly-caking Pittsburgh seam coal was established and added to with each test conducted. Successful operation of the single-stage gasifier reactor with oxygen was demonstrated with this series of tests with some rather significant results. Summaries of these results are given.
