Advanced Development of a Short-Residence-Time Hydrogasifier. Second Quarterly Technical Progress Report, January 1-March 31, 1979

摘要

A joint decision was made by the Rockwell Program Office and the DOE Program Manager to scale-up the previously planned 1/4-TPH system to a 3/4-TPH system, without any major changes in the hardware except for the injector. Since the design of the 1/4-TPH injector was still incomplete, this decision did not upset the schedule significantly. Work on the 1/4-TPH injector design was immediately terminated, and the adaptation of the previously successful 1-TPH liquefaction injector design was activated. Minor modifications to the 1-TPH design were made so that the injector could be accommodated within the existing pressure vessel as a nominal 3/4-TPH hydrogasifier injector. Based on this design, one injector made out of Type 321 stainless steel was fabricated and delivered to the test stand. Another injector made out of Inconel 625 is scheduled to be completed during the next reporting period. Other existing reactor hardware components were reevaluated with the viewpoint of assessing the need for any modifications. The needed modifications were completed, and all of the hardware was readied for installation at the test stand during this reporting period. Design work on the hydrogen-cooled recuperator was initiated. The purpose of this recuperator is to recover the sensible heat from the reaction products by transferring it to the reactant hydrogen. A three-module, shell-and-tube, counterflow type of heat exchanger concept has been chosen for this recuperator, and detailed design drawings were nearly completed. (ERA citation 05:000009)
