A wood-fired power plant in the east of France has relied on STAG bulk handling. The two inclined trough chain conveyors are fed directly from the incinerator and convey the hot ash to the storage silos. The storage silos were provided with all necessary discharge aids and a big bag pick-up cross. With this combination, a faultless ash removal is ensured and the customer has a simple and low-maintenance system.
Applied Main Components

The Big-Bag Uptake Cross is a welded construction, which has been further refined by STAG during the last 50 years. The spring-loaded karabiners simplify the hanging in an out of the Big Bags. The bag clamp ensures that the dust exposure is reduced to a minimum.
Chain conveyor are continuous conveyors and are suited for the conveyance of bulk products of all kind up to small-sized products and sludges.
The mechanical discharge aid „Silex“ is used for conveying poor flowing and not fluidizable bulk products. It is incorporated into round or angular-shaped silos, bunkers and containers.
