Description:
The paper describes EPA work in several areas relating to reducing SO2 and NOx emissions from coal-fired utility boilers, and provides an overview of objectives, approach, current status, and plans for each. In addition, it describes plans for a small-scale selective catalytic reduction (SCR) system. SO2 and NOx are major pollutants resulting from fuel combustion. oal-fired utility boilers account for about 65% of the SO2 and 29% of the NOx emissions in the U.S. hese pollutants are generally believed to be major precursors of acid rain, and their control is a significant concern of the U.S. EPA, the utility industry, and other private and public organizations. The national strategy for reducing acid rain is still being debated in Congress; the choice of a strategy will determine the control techniques for limiting SO2 and NOx emissions from utility boilers and will most likely include a mix of technologies to achieve the desired reduction at minimum cost.
