Abstract
Powdered ore is fed into fluidized bed reactor 1 after preheating by hot blast in preheating furnace 2. Iron oxide particles are recovered from an exhaust gas of the preheating furnace 2 by dust catcher 3, and the iron oxide particles are reduced to iron in reducing furnace 4. The reduced iron particles are added into the flow path of fluidized bed reactor 1 to catalyze the reaction producing iron carbide.
