Dry coal shed is a large warehouse for coal storage in thermal power plants. Due to the requirement of environmental protection and the strict control of construction land, coal bulk must be closed storage and loading, so the construction of dry coal shed has developed vigorously in recent years.

The main function of dry coal shed structure is to put a cap on the coal yard to against rain and wind, which is an energy saving and environmental protection project. The length and width of the structure are determined according to the coal capacity. The height of the structure is determined by the operating requirements of coal heaps and bucket turbines. Therefore, dry coal shed structure is characterized by large span, high height, and wide coverage area.
