SNCR and Plant Upgrade of the Filborna Waste-to-Energy Plant

Babcock & Wilcox has designed and supplied hundreds of waste-to-energy (WtE) and biomass units around the globe, with around 25 in Europe since 2005.

Many plants are looking to address common challenges:

• Improve plant operations – increase availability and reduce downtime
• Reduce NO_x and other emissions
• Lower carbon intensity levels

About Filborna:

• Plant type: Combined Heat and Power (CHP) Waste-to-Energy
• Located in Helsingborg, Sweden
• Supplies approximately 40 percent of Helsingborg’s heating demand using 100 percent of the energy in the waste
• Background:
  • Commissioned in 2013
  • 2018: Upgraded to 113% thermal input
  • 2020: Upgraded selective non-catalytic reduction (SNCR) system

As part of the project, B&W Renewable conducted a bottleneck analysis of the grate, safety valves, feeding pumps, combustion pumps, combustion fans, air pre-heater, venturis, essential control valves and boiler’s velocity and temperature, and discovered the SNCR was not performing as it should as well as other opportunities for operational improvement.
