Performance of selective catalytic reduction technology at electric utility boilers in the united states, germany and sweden

摘要

In January 1996 the Environmental Protection Agency's Office of Air and Radiation initiated an effort to locate and collect NO_x emissions data from coal-fired electric utilities using selective catalytic reduction (SCR) to reduce NO_x emissions. SCR applications in the United States, Germany and Sweden were examined, and, as of this report, SCR related NO_x data from fourteen utility plants and twenty-five separately monitored coal-fired boiler units have been obtained. Continuous hourly or half-hourly data were obtained for eleven units, and summary data covering up to a year were obtained for fourteen. Summarized in Table 1 are the data received to date. At the request of several German utilities, the identities of plants in Table 1 have been coded to maintain confidentiality.
