Ash Handling Solutions for Coal-Fired Power Generation
We provide highly-reliable ash handling systems and pneumatic conveying solutions for coal-fired power plants.
Our dense-phase pneumatic conveying technologies are widely used for the transport of fly ash, bottom ash, and other combustion by-products from boiler hoppers, electrostatic precipitators (ESP), and fabric filters to storage silos or disposal systems. Clyde systems are specifically engineered to withstand the abrasive nature of power plant ash, ensuring reliable, efficient operation with minimal maintenance.
With installations across Europe, Asia, the Middle East, and the Americas, Clyde Pneumatic Conveying has built a strong reputation for delivering robust power plant ash-handling equipment that operates reliably in some of the most demanding environments in the energy sector.
Proven Ash Handling Expertise
Ash handling systems in power plants operate under continuous duty, abrasive conditions and strict environmental requirements. Our systems are designed to deliver:
- Reliable long-distance ash transport
- Low conveying velocities to minimise pipeline wear
- Reduced compressed air consumption
- Stable operation with abrasive materials
- Minimal maintenance and downtime
Our solutions are widely used for conveying:
- Fly Ash
- Bottom Ash
- Boiler Ash
- Economiser Ash
- Air Heater Ash
- Sorbent Residues
These materials are typically conveyed from boiler hoppers, electrostatic precipitators (ESP), fabric filters and air heater hoppers to intermediate storage silos or disposal systems.
Dense Phase Conveying for Power Plants
We specialise in true dense-phase pneumatic conveying, the most efficient method for transporting abrasive ash materials.
By conveying at low velocities and high solids loading, our systems provide major operational advantages over dilute phase alternatives:
- Significantly lower pipeline wear
- Reduced energy consumption
- Improved system reliability
- Longer equipment service life
Dense-phase conveying is particularly beneficial for the highly abrasive nature of coal combustion ash, ensuring reliable operation over many years of service.
Industry-Leading Dome Valve Technology
At the heart of many Clyde ash-handling systems is the world-renowned Dome Valve, widely regarded as one of the most reliable isolation valves for pneumatic conveying applications.
The Dome Valve incorporates a unique inflatable seal design, allowing it to operate reliably even when handling highly abrasive and difficult materials.
Key advantages include:
- Bubble-tight sealing
- Minimal wear on sealing surfaces
- Long operating life
- Low maintenance requirements
- Proven reliability in power plant ash systems
This technology has been extensively proven in ash handling systems worldwide, making it the preferred valve solution for demanding power generation applications.

Global References in Ash Handling
Clyde Pneumatic Conveying has delivered hundreds of ash handling systems and components worldwide, supporting major power utilities and EPC contractors.
Our long-standing focus on this sector means we understand the operational challenges faced by power plant operators, enabling us to deliver solutions that prioritise reliability, efficiency and lifecycle cost reduction.
Ongoing Support for the Global Installed Base
While coal-fired power generation historically formed a core part of Clyde Pneumatic Conveying's business, the number of new coal power plant developments in many regions has reduced as the global energy sector evolves.
However, many plants worldwide continue to rely on pneumatic conveying systems for reliable ash handling, and maintaining these systems remains critical for safe and efficient plant operation.
Clyde Pneumatic Conveying remains fully committed to supporting this extensive global installed base, providing OEM expertise and long-term lifecycle support.
Our services include:
- Genuine CLYDE OEM spare parts
- Dome Valve servicing and refurbishment
- System upgrades and reliability improvements
- Replacement vessels and valves
- Technical support and troubleshooting
- Field service and maintenance
With decades of experience in ash handling systems, Clyde continues to support power plant operators in maximising equipment life, maintaining reliability and reducing operating costs across existing facilities worldwide.
