Energy Conservation Project Example - Murphy Plywood

CLIENT: PP&L/Murphy
LOCATION: Sutherlin, Oregon
The scope of this project was to determine the existing and desired veneer drying
capacity, analyze refurbishing methods of existing dryers, consider natural gas and
biomass heat generation, examine radio frequency redrying, and summarize
findings to make recommendations for reducing the dryer energy consumption.

The steps followed in this study were as follows:

• Held meetings with Murphy Company to determine near and long term
  required drying capacities
  
• Determined existing boiler capacity , efficiency, and examined the
  condensate system
  
• Examined biomass resources and burners
  
• Provide conceptual redesign, biomass heating design, forecast of
  increased drying capacity, and capital cost report
  
• Provided operating cost projections for natural gas, biomass heating, and
  determined biomass requirements and availability
  
• Examined latest developments in RF drying
  
• Assembled a report containing recommendations for each of the four
  existing veneer dryer upgrades including benefits, capital costs, and
  operating costs
  
  

Evergreen provided the services field collection of data, engineering calculations
and planning, equipment and resource research, and the report compilation in
completing this project.
