ABSTRACT:
A method and apparatus for preheating a reactor feed, comprised of an iron ore (10) and a process gas (21), in an iron carbide process for making steel is provided. The apparatus comprises a process gas preheater (40) having a furnace (56) and a heat exchanger (58). The process gas (21) is heated uniformly in tubes (117) of furnace (56) by burners (100). Excess heat generated by furnace (56) is captured by heat exchanger (58) and used to preheat combustion air (61) and ore (10).
