EfW and Biomass plants generate a variety of by-products throughout the combustion and flue gas treatment process. These materials are often hot, abrasive, fine and sometimes hazardous, requiring carefully designed handling systems.

Typical materials handled include:

• Fly ash from boilers and economisers
• Air pollution control residues (APC residues)
• Boiler ash and heat recovery ash
• Biomass ash
• Sorbents such as lime or sodium bicarbonate
• Activated carbon used in flue gas treatment
• Filter dust collected in bag filters or electrostatic precipitators

These materials require fully enclosed, reliable handling systems to prevent emissions, protect plant personnel, and maintain environmental compliance.

Biomass power generation continues to grow as part of the global energy transition. Many traditional coal-fired power stations are being converted to operate on sustainable biomass fuels such as wood pellets and other renewable feedstocks.

These conversions introduce new materials handling challenges, particularly in the controlled feeding and injection of biomass fuels into the combustion process.

Clyde's ROTOScrew technology has been successfully deployed on a large-scale coal-to-biomass power plant conversion in the North East of England, demonstrating reliable and controlled feeding of biomass fuels in demanding power generation applications.
