Description:
The report summarizes the key technical results of a joint demonstration project between the U.S. Environmental Protection Agency and the Taiwan Environmental Protection Administration. The project demonstrated that coal reburning can be used to reduce nitrogen oxides (NOX) emissions by at least 50% from industrial boilers in Taiwan with no adverse impacts on boiler performance or operation. The host site was a 70-ton/hr front-wall-fired boiler located at the Cheng Loong Corp. paper manufacturing facility in Tao-Yuan County, Taiwan. The Cheng Loong boiler was retrofitted with a coal-reburning system in the summer and fall of 2000. The new coal-reburning system includes coal and air injection systems as well as new dynamic classifiers. Start-up and commissioning of the system began in the fall of 2000. Problems with mill performance caused the optimization tests to be postponed until the fall of 2001. Results of the optimization and compliance tests showed that NOX emissions can be reduced by more than 50% and that carbon monoxide emissions can be kept consistently below 60 ppm. Fly ash samples showed a wide variation in loss-on-ignition values due to changes in mill performance.
