Major activity was directed toward maintenance and modification of the PDU in preparation for the 1982 test program. Numerous items of equipment were inspected, disassembled, cleaned or reworked, as required. In addition, recasting of the gasifier and the C-119 primary cyclone refractories was completed; the full primary cyclone (C-119) cold wall was fabricated, hydrostatically pressure tested, and installed; a new water distribution box was installed in the quench scrubber; and a new gasifier-to-primary-cyclone spool piece was fabricated. Refractory cure, pressure testing, and hot air dryout were begun on March 22, and test TP-032-1 was initiated on March 30. The primary objectives of test TP-032-1 are to shakedown the full cyclone cold wall and to evaluate the fines recycle system. Following completion of this test in April, test TP-032-2, an oxygen-blown gasifier and component development test, will be conducted during May and June. Cold flow scale-up facility (CFSF) testing included completion of TP-M003, a velocity profile measurement test. During a total of 484 hours of operation, jet penetration, bubble diameter, and bubble frequency measurements were obtained at two grid air injection points for eight flow parameter set points. In addition, impact pressure profiles were measured at five pitot tube locations for the eight set points. Major areas of process and component engineering and design included: Preliminary design of the PDU modifications required for hot fines recycle testing; and installation of the water-cooled cyclone barrel in the primary cyclone and the water-cooled piping spool from the gasifier to the primary cyclone.
