Andritz has installed new equipment including a new gas valve train as well as a new burner management system for electronic control of the air/gas ratio to optimise the combustion process over the entire burner output range. This will increase burner performance while reducing gas consumption by up to 4 per cent. CO2 and NOx emissions will also be considerably reduced, and safety improved.

“Our close cooperation with Andritz Novimpianti has enabled a smooth and quick start-up of the upgraded combustion system. With this upgrade we have not only optimised the performance of our burners but also made our operations safer and more sustainable. Andritz’s tailor made approach perfectly met our needs,” Lee Mc Donald, project engineer at Essity Prudhoe mill, said.

“We are very honoured that Essity again placed their trust in us for this project and happy to continue our close collaboration for sustainable tissue production,” Gianni Pellini, project manager at Andritz Novimpianti, said.

Essity is a Sweden-based leading global hygiene and health company with five manufacturing sites throughout the UK. Trends such as longer life expectancy, higher living standards and greater awareness of hygiene and health support the group’s growth, which is based on successful innovations, digital transformation, leading sustainability work and efficiency improvements.
