Gas reburn retrofit on an industrial cyclone boiler
- and others
Eastman Kodak Company`s cyclone boiler (Unit No. 43), located in Rochester, New York, is being retrofitted with the gas reburning technology developed by Babcock & Wilcox (B & W) to reduce NO{sub x} emissions in order to comply with the Title I, ozone nonattainment, of the Clean Air Act Amendments (CAAA) of 1990. The required NO{sub x} reduction from baseline levels necessary to meet the presumptive limit set in New York`s regulation is about 47%. Eastman Kodak and the Gas Research Institute (GRI) are cosponsoring this project. B & W is the prime contractor and contract negotiations with Chevron as the gas supplier are presently being finalized. Equipment installation for the gas reburn system is scheduled for a September 1995 outage. No. 43 Boiler`s maximum continuous rating (MCR) is 550,000 pounds per hour of steam flow or approximately equivalent to 60 MW{sub e}. Because of the compact boiler design, there is insufficient gas residence time to use pulverized coal or oil as the reburn fuel, thus making it a prime candidate for gas reburn. Kodak currently has four cyclone boilers. Based on successful completion of this gas reburn project, modifying the other three cyclone boilers with gas reburn technology is anticipated. The paper will describe B & W`s gas reburn data from a cyclone-equipped pilot facility (B & W`s Small Boiler Simulator), gas reburn design information specific to Eastman Kodak No. 43 Boiler, and numerical modeling experiences based on the pilot-scale Small Boiler Simulator (SBS) results along with those from a full-scale commercial boiler.
