FlueGas Treatment | Graymont
Lime and limestone play a significant role in the removal of pollutants from the fluegas streams of coalfired power plants, incinerators and industrial facilities. Lime and limestone are used in the treatment of pollutants such as sulfur dioxide (SO 2 ), hydrogen chloride (HCl), hydrogen fluoride (HF), sulfur trioxide (SO 3 ), Asenic (As), Selenium (Se), fine particulates and mercury (Hg).
Scrubbers SourceWatch
Due to Clean Air Act regulations, most scrubbers in coal plants are used to remove sulfur emissions from coal and lessen the formation of acid rain. In this use, scrubbers are large towers in which aqueous mixtures of lime or limestone absorbers are sprayed through the emissions, known as flue gases, exiting a coal boiler.

What is coal used for?
Coal is primarily used as fuel to generate electric power in the United States. The coal is burned and the heat given off is used to convert water into steam, which drives a turbine. In 2012, about 39 percent of all electricity in the United States was generated by coalfired power plants, according to the Energy Information Administration.
When to Use Lime as a Soil Amendment for Your Lawn
Types of Lime. The lime you apply to a lawn is limestone or chalk. The main component is calcium carbonate. There are several types of lime, and a good soil test should tell you which type of lime you need. Lime with a high calcium content is referred to as calcitic lime and has the benefit of adding calcium to the soil.
Electricity Generation | Department of Energy
Dry steam power plants systems were the first type of geothermal power generation plants built (they were first used at Lardarello in Italy in 1904). Steam technology is still effective today at currently in use at The Geysers in northern California, the world's largest single source of geothermal power.
Coal | Facts, Uses, Types |
Coal was used commercially by the Chinese long before it was used in Europe. Although no authentic record is available, coal from the Fushun mine in northeastern China may have been employed to smelt copper as early as 1000 bce. Stones used as fuel were said to have been produced in China during the Han dynasty (206 bce –220 ce).
