For manycementproducers in the United States, the conversion from fuel oil and natural gas to pulverizedcoalhas been difficult, frustrating, and in a few cases, very costly. This study deals mainly withcoalsafety requirements in thecement industrywhich accounts for a very small percentage ofcoalusage in pulverizedcoalfiring systems.
