5. Coal selection Use of coal as a fuel in cement or power plant operations can present special problems to a plant operator because of the wide range of coals and quality of coal available on the market. To ensure safe operation of a pulverized coal fuel system, operating parameters will change as the type of coal or blend of coals is varied.
They can take air with 3% oxygen from the preconsigner and feed it to the mill, which normally has an inert atmosphere. Things can go wrong because the oxygen concentration can drop and suddenly go up, and as soon as it becomes more than 12 or 13%, an explosive atmosphere starts. The only thing missing is the ignition source.
