Coal Storage Silo System

The technology of silo storage for coal is often used in power plants and coal mines.

Coal storage silo system.

The silo can be involved in the operation scheduling of the belt conveyor system as virtual energy storage resource which can convert the energy consumption of the belt conveyor into coal potential energy for storage through the response to electricity price and further realize the decoupling of coal flow and energy flow on the time scale and eventually reduce the running cost of the belt conveyor. Enclosed silo storage solves these problems at the smallest possible footprint. Recently we received the order for two 100 000 m3 coal silos to be built at the shidonkou first power plant in shanghai. With this order the china huaneng group initiates their shift from open and shed storage to environmentally friendly.

Coal storage silo is a coal storage method developed in the late 50s. When the coal quantity is large the silos will be built into silo groups. Coal is a very good insulator so a deep seated fire may not produce extremely high temperatures on the exterior surfaces of a silo or bunker. Designed specific for use in coal and biomass storage silos silowatch ensures the protection of people plant and process.

Concrete silo and steel silo are both wildly used in coal storage concrete silos cost more money and time to built one. Shidonkou power station chooses enclosed coal storage. A concrete silo requires a long construction period and high investment but a steel silo can be quickly built with less budgets. Screw conveyors distribute the material evenly while the auger frame rotates.

The eurosilo system for coal storage consists of a concrete slip formed silo shell ranging from 30 up to 70 metres in diameter. The silo building is erected on a concrete foundation including a concrete reclaim runnel and is covered by a structural steel roof. Concrete silos and steel silos are both usually used as coal storage silos. Since lipp coal storage silo is more popular and has more advantage than concrete silo.

When the coal quantity is small the coal storage silos are arranged in a single line. The material is fed from the top into a chute through which it reaches an auger frame on the coal surface. Coal storage silo are used in some power plants and coal mines. The eurosilo system offers safe storage up to 100 000 m per unit.

The steel coal storage silos are generally steel structures with a cone shell top a cylindrical silo body and an inverted cone bottom funnel. The storage height varies from 30 up to 50 metres depending on the soil conditions.
