KGRA Energy, Lake Forest, Ill., USA, a waste heat recovery developer, this week signed a contract with Weyerhaeuser Co., Federal Way, Wash., for its subsidiary Ayden HTP Partners to design and construct an 800 KW waste heat recovery system at Weyerhaeuser's Greenville, N.C. lumber mill. The system, scheduled to come online in the summer of 2011, will recover waste heat from Weyerhaeuser's biomass-based thermal drying system to generate 4.5 million KWh of carbon dioxide-free electricity per year. KGRA's system will displace the equivalent of more than 9 million lb of carbon dioxide per year.
KGRA Energy's system uses the organic Rankine cycle to recover waste heat from sources such as combustion engine exhausts, furnaces, boilers, and kilns. KGRA's systems are modular and scalable, providing the ability to produce power from smaller and lower-temperature heat sources previously deemed unsuitable for standard cogeneration. At the Weyerhaeuser lumber mill, heat will be recovered from a kiln where cut lumber enters the drying process. Installation of the project is expected to begin in June and the plant plans to be operational by the end of July 2011.
