The Clyde Ash Vessel (Compact) is the smallest pneumatic conveying vessel in the Clyde product portfolio. It is specifically designed to handle small quantities of coarse or gritty materials from multiple collection points.
Originally developed for handling boiler grit from industrial shell boiler grit arrestors, the Ash Vessel Compact provides a simple, highly reliable method for conveying small quantities of material collected from multiple hopper outlets, such as grit arrestors or multi-cyclones upstream of ESP systems.
Its compact footprint and single-piece construction make it particularly suitable for retrofit applications, allowing installation in restricted spaces beneath existing process equipment while still delivering dependable dense phase conveying performance.
The system is typically used to convey coarse or gritty materials over distances up to 150 metres, making it ideal for localised ash or grit transfer systems.
Key Features
- Compact Design: Smallest of all Clyde pneumatic conveying machines, allowing installation in restricted retrofit locations.
- Multi-Outlet Hopper Capability: Designed to handle material from multiple hopper outlets.
- Simple Construction: Single-piece vessel with a single inlet Dome Valve supplied fully assembled.
- Low Installation Effort: Delivered ready assembled to minimise site installation work.
- Reliable Operation: Proven components ensure dependable performance.
Typical Applications
The Ash Vessel (Compact) is commonly used in systems where small volumes of coarse particulate material must be removed from multiple process collection points.
- Boiler Grit Arrestors: Removal of grit from industrial shell boilers
- Multi-Cyclone Dust Collectors: Handling grit or coarse dust collected upstream of ESP systems
- Small Ash Collection Systems: Localised fly ash or grit transfer
- Multi-Outlet Hopper Systems: Collection from 2–4 process hopper outlets
Typical Performance
- Conveying Rate: Up to 0.5 tph
- Conveying Distance: Up to 150 m
- Material Size: 0.1 – 5 mm gritty materials
- Installation: Typically installed beneath 2–4 process hoppers
These systems are designed to maintain stable, dense-phase conveying conditions even with coarse particulate materials.
Optional Design Features
- Electro-Nickel Dome Coatings: Improved wear resistance when handling abrasive materials
- High Temperature Design: Water cooling available for operating temperatures up to 450°C
- Flexible Mounting Options: Can be mounted as a hopper or floor-mounted, depending on the installation layout
System Reliability
The Ash Vessel Compact incorporates proven Clyde Dome Valve technology, ensuring reliable sealing and isolation during each conveying cycle.
Key reliability benefits include:
- Zero leakage sealing from the inflatable Dome Valve seal
- Over 1,000,000 operating cycles between major overhauls
- Approximately 250,000 cycles before seal replacement
- Consistent operation across a wide range of process conditions
The design ensures that process hoppers remain nearly empty, reducing the risk of bridging or material blockages.
