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.

KEY WORDS:coal dust, fires and explosions,cementplants,coalfired systems, safety To achieve the goal of safe, efficient, and economicalcoalfiring system designs, both users and regulatory personnel must have an understanding of the hazards involved incoalfired systems and the nature of the problems involved in the use of pulverizedcoal.
There appears to be a general consensus in cement production that there isn’t a dust explosion hazard, aspowdered cementis not a combustible dust. This often means that there are no prevention or protection measures in place for the coal milling systems.
Different types ofcoalhave different uses. Steamcoal- also known as thermalcoal- is mainly used in power generation.; Cokingcoal- also known as metallurgicalcoal- is mainly used in steel production.; Other important users ofcoalinclude alumina refineries, paper manufacturers, and the chemical and pharmaceutical industries.
