This produces pig iron. Pig iron is the basic ingredient to produce steel. Coal therefore plays three roles in the production of steel: a reducing agent, to turn the pig iron to coke; a source of energy to drive the process by breaking apart molecular bonds; and a source of carbon for the final product (steel is an alloy of carbon and iron).

Pulverized coal to 150-200mesh and sprayed into the furnace can burn more fully. Impurities can be effectively removed in the grinding process, and the burnout rate is higher. (1) Grinding Stage: Moist coal should be dried first, and then sent to the main grinding room for grinding.

The heating and circulation of the hot semi-coke powder is completed in the heating riser with gas–solid two-phase flowing. This process is separated from the coal pyrolyser to prevent the flue gas used to heat semi-coke powder from being mixed with coal gas. As a result, coal gas with high heating value can be obtained. 3.
