Auxiliary equipment is used to perform support operations in a typical coal handling system. Support operations, such as weighing coal and collecting coal samples, help provide important information for coal handling and other plant operations.This training program explains why coal is weighed and sampled, and describes some of the auxiliary equipment used to perform these jobs. It also covers some of the preventative maintenance tasks that coal handlers may perform to keep auxiliary equipment in good working condition.
