32-Month Gasifier Mechanistic Study and Downstream Unit Process Development Program for the Pressurized Ash-Agglomerating Fluidized Bed Gasification System: Quarterly Report, October 1-December 32, 1986

摘要

During this past quarter, the TP-037 series of tests conducted to date demonstrated: a sulfur loading of the desulfurizer zinc-ferrite bed to >30 wt. %; a steady decrease in supplemental steam use per pound of product gas; sharp radial; temperature and sulfur loading gradients existing within the desulfurizer zinc-ferrite bed; and steam regeneration, one-tenth the rate of oxygen regeneration at two volume percent oxygen. Other work completed was: a Test Program Scope for PDU testing in 1987, revisions to the jet temperature model as discussed in section 7.0 and Appendix A, and an assessment of a material failure that occurred in the first cold wall spool piece at the gasifier exit. 5 refs., 51 figs., 51 tabs.
