IS 11860 : 1998 Guidelines for non -coking coals for solid reductant based direct reduction in rotary kilns(and other reactors

1 Scope

This standard covers the guidelines for non-coking coals forsolid reductant based direct reduction (DR) processes in which thereactor is either a rotary kiln or a shaft type in which thereductant is charged directly without gasification in a separateunit.
