Abstract
A combustion chamber in a melter gasifier extends into a fluidized bed to isolate fine particulate ore introduced into the chamber from the remaining internal portion of the melter gasifier. The fine particulate ore is melted in the chamber and falls on the bed to be reduced as it trickles down to the molten metal in the melter gasifler bottom. Reducing gases withdrawn from the melter gasifier are filtered through the bed, thereby preventing the fine particulate ore from being withdrawn with the gases. The chamber can be liquid cooled and use a burner to provide combustion temperatures.
