Pulverized coal. Pulverizedcoal combustion is widely used in large power stations because it offers flexible control. In this method, coal is finely ground so that 70 to 80 percent by weight passes through a 200mesh screen. The powder is burned in a combustion chamber by entraining the particles in combustion air. Because finely ground coal has more surface area per unit weight than larger ...

How does coke and coal play into steel making?

How does coke and coal play into steel making?

+

 · Coke is made by either byproduct or nonrecovery methods. In byproduct coke, impurities are baked off at between degrees Fahrenheit to leave almost pure carbon. The ovens used must admit no oxygen to avoid reaction with other elements that could leave impurities. As the coal is "coked" it softens to a liquid, but solidifies to a porous material on cooling. The gases produced .
