A waste and recycling processor plant in the United Kingdom was experiencing problems with the existing valves located on the outlet of their bulk storage silos. The client’s process includes bulk storage, discharge and transfer of a variety of residues, which are the by-product of incinerating chemical, clinical and municipal wastes. These are solids and residues from flue gas treatment, APC, FTG and fly ash.
Due to the aggressive and varying nature of the materials being handled, the existing valves had difficulties opening and closing through a standing column of material.
The Vortex® Titan Slide Gate™ (TSG) was identified as the ideal solution for this application. The TSG is designed for handling heavy-duty, abrasive dry materials in gravity flow applications. Beneficial features of the TSG include a positive material shut-off and dust-tight sealing capabilities.
Because this client’s process had high-pressure silo discharge aeration, the TSG was equipped with a return pan to prevent leakage of materials and dust to atmosphere, the TSG was equipped with a return pan.
A return pan is a fabricated metal piece designed to transition the outlet side of a gate. It is angled to create an inverted “ramp” – beginning narrow at the back of the gate and gradually steepening as it approaches the gate’s opening.
For ease of maintenance, the TSG features milled access slots on each side of the gate’s frame so that bonnet seals can be replaced quickly and easily replaced whilst the gate remains in-line.
