Particulate Matter

Standards for the control of particulate emissions were first introduced in the early 1900s in Japan, the United States, and Western Europe [52]. Over the decades, they have become increasingly more stringent and widespread, with recent emphasis being placed on the control of fine particulate matter. Similar to those for NOx and SO2 emissions, international agreements have been signed to reduce particulate emissions from coal-fired power plants. The EC set limits for particulate emissions from coal-fired power plants in the LCPD. These set particulate emissions limits of 100 and 50 mg/m3 for new plants with capacities of 50 to 500 and >500 MWt, respectively [52]. Even stricter limits are under review to conserve the environment and human health. Increasingly more stringent national emission standards have been adopted in Japan, North America, and Western Europe. The growing importance of using coal in an environmentally acceptable manner for power generation as well as in the industrial and residential sectors has led to the introduction of particulate emission standards in other countries as well. Currently, 30 countries have emissions standards for particulate emissions from coal-fired power plants [52]. Examples of particulate emissions standards in some of these counties are provided in Table 4-12 [51].
