A bunker container is a storage device for shredded fuel in the form of sawdust, wood chips, shavings or dust. Its design and equipment ensure self-discharge of the fuel stored in it at a maximum of 21 m3. These devices can function as mobile fuel storage facilities. This is made possible by the unified design typical of "hook" containers. Thanks to the use of quick couplers, the replacement of the filled container is smooth without having to stop the operation of the furnace. The containers can also be a destination fuel storage facility successively filled, for example, with a loader.
The mobile structure is based on a set of scrapers located at the bottom of the container. A transverse auger or redler ensures complete emptying of the container. The container can be connected directly to the furnace, or it can act as an intermediate tank for filling up smaller furnace trays.
This solution makes it possible to operate the furnace plant away from the fuel source, without the need to build large fuel silos or stationary storage facilities.
