Coal Dust Control

摘要

Where there is coal,there is coal dust,one of the biggest nuisances for coal-fired power plants. The U.S. produces more than 1 billion tons of coal each year, and more than 90 percent is used to generate electricity at U.S. power plants. Altogether, the nation's 1,400 coal-fired units consume more than 900 million tons of coal each year, according to the Energy Information Administration, the statistical arm of the U.S. Department of Energy. For power plants handling millions of tons of coal a year, minimizing coal dust is a high priority. A wide range of techniques are used to manage, control and prevent coal dust in and around coal-fired power plants.
