Description:
There have been substantial reductions in emissions of particulate matter, nitrogen oxides, and sulfur dioxide through the application of control technologies and strategies. The installation of control technologies has added to the complexity of coal-fired boilers and their operations. As plant complexity has increased, so has the potential for unintentional and undesirable consequences. One of the more noteworthy adverse consequences is the formation and emission of sulfur trioxide and associated sulfuric acid aerosol. EPA is examining approaches to prevent and reduce excessive sulfur trioxide and sulphuric acid emissions. Reduction approaches include injection of alkali sorbents into the downstream of the furnace, injection of ammonia upstream of the air preheater, and installation of a wet electrostatic precipitator.
