Question

explain flow diagram of production of iron with neat sketch.
​

Answer 1

Answer:

The ironmaking process in the blast furnace is a heat and mass transfer process, and the furnace can be divided into different zones according to physical and chemical state of the feed and temperature. Figure 1.1.5 illustrates various zones of the blast furnace and feed distribution and materials flow [13]. Corresponding to each temperature interval, typical reactions will take place. The descending burden is dried and preheated during its descent by the ascending gas. The preheated blast is blown into the furnace through the tuyeres in the lower part of the furnace. Oxygen in the blast reacts with coke carbon to produce carbon monoxide and blast humidity reacts with carbon to produce carbon monoxide and hydrogen
