Power Boiler Emissions Upgrade
Client: West Fraser
Location: Williams Lake, BC
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.
