Engineering support services for the DOE/GRI coal-gasification research program. Technical consultation on the Westinghouse process development unit

Technical Report ·
OSTI ID:5618624
DOE requested that Pullman Kellogg provide technical consultation on the Westinghouse P.D.U. This task involves three major areas along with several points of consideration within the areas, including: (1) Gasifier Cyclone Modifications and Controls; (2) Estimation of PDU Gasifier Heat Loss; and (3) Pneumatic Transport of Wet Coal. It was concluded: (1) that the cyclone modifications will improve performance (two further modifications are suggested) and that the existing controls are sufficient. (2) Pullman Kellogg estimates a lower PDU heat loss than Westinghouse (by about 25 percent) with some causes of the difference identified. The heat loss is about 13.5% of the heat of reaction on the PDU but is estimated to be only 0.5 percent on a commercial size unit. (3) Empirical data from various vendors suggest the moisture control of the coal be kept below 7.5% to avoid agglomeration.
