Abstract
A highly efficient method and apparatus for production of molten iron using coal by coal gasification in a molten iron gasifier-melter. The gasifier-melter is coupled to a direct reduction shaft furnace and utilizes both the gaseous and solid output of the shaft furnace. The process is especially efficient when using non-metallurgical coals.
