Electrostatic precipitator
Other power plants may look to remove certain pollutants such as sulfur dioxide or look to minimize the amount of ash produced. Additionally, some lowsulfur coals that are burned have a higher electrical resistivity, which makes it more difficult to remove the ash produced by this coal using electrostatic precipitators. Effectiveness . Electrostatic precipitators are extremely effevtive ...

How Gas Turbine Power Plants Work | Department of Energy
Gas flowing through a typical power plant turbine can be as hot as 2300 degrees F, but some of the critical metals in the turbine can withstand temperatures only as hot as 1500 to 1700 degrees F. Therefore, air from the compressor might be used for cooling key turbine components, reducing ultimate thermal efficiency. One of the major achievements of the Department of Energy's advanced turbine ...
