Method and a means for introducing close-grained carbonaceous fuels into a molten iron bath

摘要

A method and a means for introducing close-grained carbonaceous fuels, which are suspended in a carrier gas, and oxygen into a molten iron bath are described. In this method the fuel and the oxygen can be alternately introduced through the same introduction passage of a tuyere into a molten iron bath below the surface of the bath. The means provides for alternate supply of fuel or oxygen and is regulated by means of the oxygen line pressure.
