This report presents work accomplished during the fifth quarter to investigate mixing and gasification of coal in entrained flow systems. Visits to Washington State University, Arizona University, and ERDA were made during the report period. Design of the major gasifier components was completed with final drawings, and fabrication of inlet components, reactor feeder, and scrubber was initiated. Secondary preheater and steam generator were ordered and delivery dates were set. A ''critical-path'' schedule for gasifier design, fabrication, and installation was developed. Particle size variation of the test coal was measured. Ten nonreacting, nonrecirculating jet mixing tests were conducted using test conditions similar to coal gasifiers. Results show particle dispersion much slower than gas mixing. Particles also seemed to retard gas mixing. Extension of this facility to permit recirculating tests was continued. Programming of the macroscopic, coal gasifier model was nearly completed, and sample input data were prepared for initial trial computer runs. Plans for the next quarter include completion of fabrication and start of assembly of gasifier components, performance of several nonreacting jet mixing tests, and debugging of the macroscopic gasifier model.
