Trippers

SKU: CHTRI00CENDuration: 60 Minutes

Coal is stored in large containers such as bunkers before being burned in a plant's boilers. Bunkers provide a coal handling system with extra flexibility. For example, most plants do not receive or reclaim coal around the clock. As long as there is coal in the bunkers though, 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.
