Conclusions after a series of runs at steady state conditions in the pilot plant are: (1) Western Kentucky No. 9 coal (either run-of-mine or washed) can be gasified without pretreatment; (2) other coking bituminous coal may also be able to be gasified without pretreatment; (3) pretreatment is not required to achieve satisfactory ash agglomeration; (4) balanced ash agglomeration with satisfactory removal of the agglomerates has been achieved and stable operation of ash agglomeration is possible during periods of short upset; (5) solutions appear to have been found for prevention of clinkering and sintering by alternative venturi design, modification in the oxygen feed system and increasing the superficial velocity of the gas; (6) under certain circumstances fines recycle has been achieved with stable operation and fluidization; (7) the process can be operated at pressures up to 60 psig without adversely affecting other process parameters; (8) a wide range of operating conditions can be used while maintaining system operability; and (9) in a single test water cooling of the cyclone appears to prevent ash deposition on the cooled surfaces which confirms the experience of Westinghouse with ash deposition prevention in their fluidized bed gasifier. 11 references, 12 tables.
