Abstract

A charging system for a shaft smelt reduction furnace includes a frame structure for mounting on a top charge opening of a shaft smelt reduction vessel; a center shaft arrangement supported by the frame structure and for removing off-gas gases from the furnace and to introduce granular charge materials to form a stack of materials in the furnace. The center shaft arrangement includes a center hood for off-gas extraction; a pair of first and second feed channels for first and second materials.
