ABSTRACT
Saarburg-OTTO A coal gasication process. Powdered coal, together with steam and oxygen, is injected tangentially into a gasier containing molten slag. Gasication in a bath of molten slag was invented by R. Rummel in the 1950s and developed by Dr. C. Otto & Company in Germany in the early 1960s. In 1976, Saarbergwerke and Otto agreed to a joint development program, which culminated in the building of a large demonstration unit at Völklingen/Fürstenhausen, Germany, which was operated from 1979 to 1982.
