Replacement Parts and Performance Upgrades

Effectively combines dry fly ash from a silo with water to form a moist mixture. This mixture is readily transferable and transportable with minimal dust emissions. The unit is fully assembled for ease of installation, uses durable materials to lengthen wear life, and is designed with accessible components for easy on-line inspection and maintenance.

Uses wastewater from a flue gas desulfurization (FGD) system for blending into the ash for processing. Provides a unique solution for ELGs. It not only minimizes the use of plant process water for ash processing, but also provides a beneficial use for FGD wastewater.

Used primarily for the transfer of fly ash or other dry, free-flowing, granular solids, the Style IV airlock design is available for both pressure and vacuum system applications. In a pressure conveying system, solids are transferred from an overhead collection point into a receiving chamber by utilizing a set of isolation gates above and below the chamber. In vacuum conveying systems, the filter collector is located above the ash storage silo. The A-S-H airlock adjusts the pressure zones between the filter collector and the silo without requiring a break in the vacuum level for continuous operation.

Suitable for regulating dry, free-flowing fly ash material into a transport system. Designed for changing or harsher operating conditions, including stickier and more abrasive ash, our Advantage Series valves encourage ash flow and minimize wear by utilizing hardened components for high-abrasion zones. They are available for lateral feed vacuum conveying systems and as a direct replacement for UCC® Tiger™ valves.

Used in pressure systems for airlock equalization and in vacuum systems for collector equalization applications, the Style Ill equalizer valve is compact, lightweight and affordable.

Replacement wear part upgrade provides improved wear life, easier maintenance and increased sealing force for greater material head support compared to Style I airlock components.

Multiple chamber design allows for continuous ash collection—even when ash is being loaded into the storage silo. The CycloASH 60 collector offers easy maintenance, extended wear life and superior sealing.

Designed specifically to feed ash into dilute-phase vacuum systems on a batch basis. The Type-H material handling valves are durable, efficient and can handle the most severe operating environments.

Refurbishment and maintenance kits for Allen-Sherman-Hoff® Style I and IV airlocks, as well as upgrade kits to convert Style I airlocks to Style IV design, these kits come complete with everything needed to refurbish your airlock to original operating condition.
