The project, developed by a partnership of KGRA Energy and Turbine Air Systems, will capture waste heat from the mill and covert the captured thermal energy into clean electricity.
North Carolina-based Roberts Company is constructing the balance of plant for the project.
Upon completion, the project will provide Weyerhaeuser’s mill about 4.5 million kWh of emission free electricity per year and displace the equivalent of about nine million pounds of carbon dioxide each year.
KGRA Energy said its system employs an organic Rankine cycle based power generation skid packaged by Turbine Air Systems at their factory in Houston,US and the skid will convert the mill’s waste heat to useable energy.
At the Weyerhaeuser lumber mill, heat will be recovered from a kiln where cut lumber enters the drying process.
Organic Rankine cycle technology recovers waste heat from viable sources, such as combustion engine exhausts, furnaces, boilers, and kilns, and converts it into usable CO2-free electricity, which lowers energy costs as well as heat pollution.
