Schwartz, C W

This paper reviewed the technical highlights of the Westinghouse coal-gasification combined cycle (CGCC) by giving: a brief history of the Westinghouse coal-gasification technology-development program; process description and discussion of the two CGCC plant designs; the results of a parametric study of the two plants, with differences between air- and oxygen-blown combined-cycle systems; and a demonstration of the flexibility of the Westinghouse gasifier in using either air or oxygen to produce fuel gas. Conclusions included were: the air-blown coal gasification combined-cycle system is more efficient, less expensive, and involves less design complexity than the similarly designed oxygen-blown systems; the Westinghouse coal-gasification process has the flexibility to use air or oxygen to produce fuel gas; environmentally, sulfur and ammonia removal will be similar in the oxygen-blown plant and the air-blown plant; however NO/sub x/ formation will increase for an O/sub 2/-blown plant; steam injection for NO/sub x/ control does not detract from overall plant thermal efficiency. 5 figures, 6 tables.
