Bulldozers are used to spread coal out on storage piles and to reclaim coal from the piles when it is needed in the plant. Bulldozers are also used to manage coal piles to reduce the risk of fires and to minimize loss from erosion due to wind and rain. Coal handlers who use bulldozers must know how to operate them safely and correctly, and how to take care of them properly. This course focuses on the use of bulldozers in coal handling operations. Emphasis is placed on practical applications, inspection procedures, minor maintenance procedures, and basic operating procedures.

COAL PILE MANAGEMENT
Plants that need to burn large quantities of coal also need to maintain large coal reserves. The most common way of storing coal is in large outdoor storage piles. Coal pile management involves moving coal to and from storage piles, and maintaining the piles to deal with coal pile fires and environmental factors such as rain and wind. This course will cover these topics, as well the equipment used in coal pile management.

COAL YARD MAINTENANCE
Coal is a heavy, abrasive, and corrosive material that can be difficult for equipment to handle. To handle coal, equipment must often run at high speeds and carry heavy loads. To do its job, coal handling equipment must be continually maintained to ensure it stays in good running condition. This course examines the maintenance jobs that are commonly performed on coal handling equipment and describes how coal handlers may be involved with equipment maintenance.

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.

DUST CONTROL EQUIPMENT I
When coal moves through a coal handling system, it produces a lot of dust, which can be harmful to those working in the plant. Coal dust can present a respiratory hazard to workers, cause fires, damage plant equipment, and cause air pollution. Coal dust must be controlled in order to reduce or prevent these harmful effects. This course focuses on the equipment that is commonly used to control coal dust in indoor locations, such as breaker buildings, tripper rooms, and car dumpers.

DUST CONTROL EQUIPMENT II
Dust from coal handling operations must be controlled to protect personal health, equipment, and the environment. There are many different types of equipment used to control coal dust, and operating it may be part of a coal yard worker’s job. Dust control equipment is classified into two main groups: equipment used to control dust inside buildings and equipment used to control dust outside in the coal yard. This course focuses on the equipment used in the coal yard.

HANDLING WET AND FROZEN COAL
Wet and frozen coal can create difficult problems for coal handlers, including clogging equipment and impeding or blocking coal flow. However, many of the problems resulting from wet or frozen coal can be greatly reduced, and sometimes entirely avoided by following certain precautions, by properly using specialized equipment, and, in some cases, by planning ahead. This course covers the types of problems caused by wet and frozen coal, as well as methods and equipment that are commonly used to avoid, minimize, or respond to these problems.

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.

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.
