CONTROL EQUIPMENT

The components of a coal handling system are operated with control equipment. The proper operation of the control equipment ensures that the components are started and stopped in the correct sequence so that coal moves smoothly from one component to the next. If one of the components in the sequence is not operated properly, the entire system could come to a stop, and equipment could be damaged. This course describes how control equipment is used to operate coal handling components so that they work together smoothly as a system. Troubleshooting procedures that can be used to determine the cause of a coal handling system malfunction also are covered.

STACKERS

Plants that burn coal typically store their coal in outdoor piles. To move the coal to the storage pile, a machine called a stacker is often used. An important aspect of coal handling is operating a stacker, coordinating its operation with the rest of the coal handling system, and keeping it in good working condition by performing regular inspections and minor maintenance. This course will cover how to follow the procedures for each of these aspects of coal handling.

TRIPPERS

As long as there is coal in the bunkers, the plant can keep running without having to get coal from the point of delivery or from the coal pile. Whenever there is an interruption or a breakdown in coal handling, having a supply of coal on hand in the bunkers allows the plant to continue operating while the problem is corrected. To ensure that the bunkers are filled with coal, plants need equipment designed for that purpose. In many plants, the equipment used to fill bunkers are machines called trippers. This course will review tripper operation and maintenance, as well as tripper room duties.
