FEATURE
MADE IN THE EAST MIDLANDS
manufacture and installation of a new DSI system at an energy-from-waste power station, near Scunthorpe, North Lincolnshire. When it was built in 1993, the plant was only the
second in the world designed to generate electricity from fuel derived from bone meal and poultry litter and now generates around 13.5 MW, enough to provide power to about 32,000 homes. In 2018, the plant’s Project and Maintenance Management team invited the Ammegen team to look at its existing, 20-year-old DSI system that was using increasing quantities of sorbent to capture unwanted emissions. The client needed expert assistance to identify root
causes of the problem while upgrading and improving performance. Ammegen was contracted to produce a design feed
study and as a result was then contracted to manufacture, supply and install the solution. Taking a unique approach, the company carried out an
extensive study of the plant’s feed system, physical operational conditions and the chemistry of the fuel used. A bespoke computational fluid dynamic (CFD) modelling package was developed to replicate and identify causes of the excessive sorbent consumption before Ammegen
engineers were able to use their experience and expertise to design an effective solution. The project identified that a significant reduction in
sorbent usage could be achieved by changing the position and injection method of the sorbent into the flue gas duct and Ammegen was contracted to install the new system. Since completion of the project, the plant has returned
to full operation with Ammegen’s bespoke DSI system upgrade performing extremely well and meeting the criteria set out in the required performance guarantees. In turn, this success has helped the plant continue to
meet its obligations to all of its stakeholders and sustain high levels of performance, while managing its operations within required regulatory emission output levels. The results of the project clearly show that, in a changing world, the East Midlands is home to businesses that are utilising state-of-the-art technology and engineering excellence to help deliver a cleaner future and we’ve since received a number of enquiries about similar projects from power plants across the globe. It also demonstrates their ability to adapt and evolve
to meet the challenges faced in an increasingly global marketplace as industries strive to reduce their emissions as part of the fight against climate change.
