Vertical Shaft Kilns

Lime shaft kilns are stationary vertical kilns where the raw limestone enters at the top and gravity flows through three thermally zoned sections known as the preheating, calcining, and cooling zon The process heats the limestone from ambient temperature to 900°C, which is the point where the carbon dioxide is driven off, leaving calcium ....

Iron processing

The blast furnace Basically, the blast furnace is a countercurrent heat and oxygen exchanger in which rising combustion gas loses most of its heat on the way up, leaving the furnace at a temperature of about 200° C (390° F), while descending iron oxides are wholly converted to metallic iron...
