China, the United States, and other countries that rely on coal for electricity production regulate emissions from coal-fired power plants, primarily for health reasons. In the United States, the 1990 Clean Air Act Amendments caused many power plants to switch to low-sulfur coal or to install flue-gas desulfurization units (FGD units, or ...
11 at the Mae Moh Power Plant, which was the subject of this project, was 45.7% - 90.0% in 1998, but in 2002 following the completion of the project, it improved to 97.0% - 98.1%. Also, the SOx concentration was 352 - 1,919 ppm in 1998 but improved to 67 - 105 ppm in 2002, reaching a level less than the standard discharge level of 157 ppm.

per year. Mae Moh lignite is generally of low quality, with 3% of sulfur content. Consequently, the power plant emits significant amount of sulfur dioxide (SO 2). To reduce SO 2 emissions, flue gas desulfurization plants have been installed to all power units since 2000 and their removal efficiencies are around 98%.
Coal-fired power plants, in addition to emitting greenhouse gases, are a major source of local pollution and health damages throughout the world. China, the United States, and other countries that rely on coal for electricity production regulate emissions from coal-fired power plants, primarily for health reasons. In the United States, the 1990 Clean Air Act Amendments caused many power plants ...
The Environmental Protection Agency (EPA) finalized the MATS rule in December 2011. The MATS rule requires that all U.S. coal- and oil-fired power plants greater than 25 megawatts meet emission limits consistent with the average performance of the top 12% of existing units —known as the maximum achievable control technology (MACT).
Mae Moh power plant uses pulverized coal combustion in superheated boilers to generate electricity.
