ABSTRACT:
The present invention concerns a method of and a device for directly reducing fine-particle ore in a horizontal reactor with an ore-reducing gas and a heat vehicle, also a gas, in a fluidized bed.
The ore-reducing vessel itself comprises a horizontal fluidized-bed reactor (1). The ore (F) is blown into it from below. The heated ore-reducing gas (A) is blown into the reactor through oncoming-gas floors (2). The heat needed for the endothermic reaction is supplied to the reactor at different temperatures through heat exchangers (3) and transferred to the bed. Heat is supplied counter to the ore-reducing gas.
Fuel (B) in the form of gas is burned with air (C) to make the heat vehicle (D). The ore-reducing gas (A') is heated in downstream heat exchangers (5.1 to 5.3) before arriving in the three sections (1a, 1b, & 1c) of the reactor through the floors.
Sponge iron (6) is removed and throat gas (E) extracted from a sponge-collecting section (1d).
