| Popis: | We discuss various charging systems for blast-furnace operations with and without injection of pulverized coal fuel (PCF) into the hearth. We also perform a mathematical simulation of the radial distribution of coke in ore charges and analyze production data on the variation in furnace-gas temperature at the burden surface across the top throat in different charging systems. An efficient blast-furnace charging system has been developed for use when pulverized coal fuel is injected into the hearth. |
