HHKW Besancon

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.
