Recently, Fullerton College upgraded its boiler room facility by installing a pair of Johnston firetube boilers that incorporate the GTI-developed forced internal recirculation (FIR) burner technology. The low-cost burner was selected to provide heat and hot water for several applications throughout the college, located in Fullerton, California. The FIR burner has demonstrated low nitrogen oxide (Nox)and carbon monoxide (CO) emissions from natural gas combustion, exceeding design targets of < 12 volumetric parts per million (vppm)* Nox and <50 vppm CO at design turndown,without any external flue gas recirculation. It can be used in a wide range of industrial and commercial boiler applications that produce paper, chemicals, petroleum products, food, and steel. Development of the FIR burner technology was sponsored by: the U.S. Department of Energy - Office of Industrial Technologies; Gas Research Institute (a predecessor company of GTI); GTI's Sustaining Membership Program; and Southern California Gas Company. Installation of the boilers incorporating the FIR burner was sponsored by: Fullerton College, Southern California Gas Company, and GTI’s Industrial Research Collaboration Programs.
