BPEI provided engineering and on-site supervision for power boiler improvements. Results were an 80% decrease in emissions and a 20% increase in efficiency for Williams Lake Plywood.

Operational improvements were made based on BPEI’s analysis of the mill’s entire mass-flow process, including:

  • backend ash collection system and disposal method
  • controls system and interconnecting ducting

Emissions reduction and improved efficiency were achieved by:

  • adding electrostatic precipitators
  • designing and adding overfire and undergrate air modifications.
