Bio-energy and bulk materials handling firm Saxlund International, part of the Opcon AB energy and environmental technology group, has collaborated with Hope Construction Materials to install and commission waste-derived fuel system for the construction materials supplier.
Located at the company’s Hope Works cement plant in Derbyshire, the largest in the UK, the system has been designed to provide storage, transportation, weighing and injection of solid waste fuel (SWF) to the two kilns at its Derbyshire site. The goal is to increase the rate at which Hope can replace fossil fuels with waste-derived alternatives to more than 50 percent.
Once fully operational, the SWF system will run on a 24/7 basis delivering fuel at a rate of up to 5,000 kg per hour to each kiln and diverting up to 80,000 metric tons of bulk solid waste from landfill each year, says Matt Drew, managing director Saxlund International.
The project incorporates a 350m3 fuel reception and Push-Floor storage solution, reclaim conveyors, process tower with drum magnet and star screen, together with a weighing and pneumatic injection system to the main burners. The system facilitates stable and reliable process conditions to help minimize build-up in the pre-heater tower, and it offers a future-proof solution with the flexibility to handle changing fuel characteristics, even different types of waste-derived fuels, should suppliers change in the future.
The installation is also designed with low maintenance and high availability in mind, with the emphasis at all times on minimizing potential restrictions or blockages, the company says. The state-of-the-art push-floor fuel bunker ensuring ‘first in, first out’ fuel delivery is critical to this. Key maintenance areas, where possible, are also external to the system to minimize disruption.
In February Saxlund International secured contracts from Barhale Trant Utilities to design and supply sludge cake truck loading silos for Southern Water wastewater treatment works in the UK.
