Title: SO{sub 2} and NO{sub x} control technologies - developments at Penn State`s Combustion Laboratory

Abstract

The majority of pollution from coal combustion is from the emission of sulfur and nitrogen oxides. The Clean Air Act Amendments of 1990 established the Acid Rain Program under Title IV to achieve significant environmental and public health benefits through reductions in electric utility emissions of SO{sub 2} and NO{sub x}. The Act calls for significant reduction in NO{sub x} emissions by year 2000. The data obtained by EPA showed that 1995 SO{sub 2} emissions declined sharply by approximately 5 million tons below 1980 levels at the 445 Phase I affected electric utilities. The data also indicated that the boilers involved in the first stage of the NO{sub x} reduction program met Phase I emission standards of 0.5 lbs/MMBtu for dry bottom, wall fired units, and 0.45 lbs/MMBtu for tangentially fired boilers. Fluidized bed combustors, due to inherently low operating temperatures, produce less thermal NO{sub x} than pulverized coal units. However, with Ozone Transport Commission`s deliberations, it is expected that NO{sub x} emission limits could be lowered even further up to 0.15 lb/MMBtu for the fluidized bed combustion Units. Therefore, NO{sub x} reduction is important not only from an acid rain point of view but also from ozone formation atmore » lower altitudes.« less
