The PRENFLO coal gasification process and experience from the Furstenh
ausen demonstration plant in Germany are described. The PRENFLO proces
s, a further development of the Koppers-Totzek process, is based on th
e entrained-flow principle with dry fuel dust feeding. Experience from
the two demonstration plants in Hamburg and Furstenhausen supplied th
e main data for the first commercial-size PRENFLO plant for Elcogas, S
.A., in Puertollano, Spain. With a net electrical output of 300 MW the
Puertollano plant is the world's highest capacity combined-cycle powe
r plant based on coal. In particular, some results from the 1992 test
programme in the Furstenhausen plant are presented.
