What is an electrostatic precipitator? What parts does it consist of?Electrostatic precipitator is a device that USES corona discharge to charge the ash particles in the flue gas and separate them through electrostatic action.

It consists of discharge electrode, dust collector, high voltage dc power supply device, vibration device and shell.

The emission of soot, sulfur dioxide and nitrogen oxides from coal-fired power plants is compared with the special emission limits for gas turbines stipulated in the air pollutant emission standards for thermal power plants (gb13223-2011). Electrostatic precipitator The situation when the gas turbines meet or fall below the emission limits is called "ultra-low emission" of coal-fired units.Electrostatic precipitator Among them, in the combustion of coal quality is more appropriate, the use of technical and economic feasible smoke pollution control technology, so that soot, sulfur dioxide, nitrogen oxide emissions are less than 10 mg/cubic meter, 35 mg/cubic meter, 50 mg/cubic meter of coal power units, known as ultra-low emission coal power units;Make smoke, sulfur dioxide, nitrogen oxide emissions are less than 5 mg/cubic meter, 35 mg/cubic meter, 50 mg/cubic meter of coal power units, known as the gas turbine unit emissions standards of coal power units.
