Bulk material sluice with rotary valve

The STAG discharge and dosing module is realized with two bulk material slides and an intermediate container. The dimensioning of the intermediate tank makes the application areas very versatile and easy to modify.

For a discharge of hot bed ash from a fluidized bed furnace, the intermediate tank was supplemented with air cooling. This option prolongs the service life of the bulk material slide valves at temperatures up to 800°C.
