Babcock & Wilcox (B&W) designed and manufactured an internal recirculation circulating fluidized-bed (CFB) boiler and air quality control equipment for a new combined heat and power (CHP) plant for the University of Alaska Fairbanks (UAF).

Project Facts and Results
UAF replaced the existing boilers originally built in 1964. The replacement CFB boiler will meet current power and steam demands as well as future growth requirements of the university.
The electricity and low-pressure steam generated will power and provide heating and chilled water to the university’s numerous buildings, classrooms, research facilities, and student housing located on approximately 3 million ft2 (nearly 69 acres, or 28 hectares) of campus property.
The sub-arctic climate in Fairbanks created unique scheduling challenges as steel construction was required to stop when temperatures dropped below –15F (–26C), and all work stopped at temperatures of –30F (–34C).
Shipping and logistics were challenging due to the location of Fairbanks (360 miles [579 km]) from the port city of Anchorage.
Emissions results indicate the unit is capable of meeting nitrogen oxides (NOx), sulfur dioxide (SO2), and particulate emissions permit limits throughout its load range.
