ROLLING BEARINGS FOR COAL PULVERIZER APPLICATION DESCRIPTION Nowadays, the ever-growing demand of alternative energy leads also to an important upgrade of traditional energy. In a coal power plants, a coal pulverizer assumes a paramount importance in order to increase boiler efficiency by providing pulverized coal with a specific granulometry.
the pulverizer throats and matching them for compatibility with the coal pipes and burner nozzle sizes is essential for the best furnace performance. Furthermore, remember that there will be minor vari-ation in mill capacity, fuel quality, and mill inlet airflow rates that must be considered when sizing the pulverizer throat flow area.
