“Wood residual-fueled 120,000 PPH 600 psig/750 °F Boiler”
Colville Indian Power and Veneer (CIPV) operates an integrated plywood manufacturing facility near Omak, Washington, and engaged PES to refurbish and repair its No.1 Power Boiler; a wood residual-fueled 120,000pph 600psig/750ºF boiler providing thermal energy in the form of low-pressure steam serving on-site veneer dryers as well as electric generation through multiple turbine-generators. PES accomplished all engineering design and engineering, specified and procured all equipment, managed construction and installation, and supported project start up on time and on budget. PES’ extensive and creative planning efforts substantially reduced the outage duration below that anticipated by CIPV.
