Coal Moisture Control

Coal moisture control reduces the moisture of the feed for coke making from a normal 8 - 10% to around 6% using low-pressure steam or sensible heat recovered from coke oven gas.  This technology reduces the carbonization heat demand, improves productivity and enhances coke quality.

The option is regarded to have high application potential for China and India, and medium potential for the United States.
