Thermodynamic Analysis of Basic Chemical Reactions of Rotary Hearth Furnace Process System
JING Guangmin
Abstract：Rotary hearth furnace process is one of coal-based direct reduction processes, its internal thermodynamic reactions have 5 part such as the reduction reaction of carbon-containing pellets, the oxidation reaction of carbon-containing pellets with oxidizing gases, decarbonization reaction of carbon-containing pellets, combustion reaction of exhaust gases of containing carbon pellet and effecting of blowing coke oven gas on the reduction etc. The controlling of the internal temperature, atmosphere, blending ratio are the key technologies of the rotary hearth furnace direct reduction process.
