Doosan Heavy Industries & Construction has developed Electrostatic Mist Eliminator (EME) that simultaneously removes white smoke and fine dust from the chimney of a thermal power plant, along with Korea Institute of Machinery and Materials.
According to the company on May 21, EME is one of the emission gas disposal systems for thermal power plants and is an eco-friendly facility that is applied to the final stage before the emissions go out into the chimney.
It can remove up to 98 percent of moisture, which is the main ingredient of white smoke from chimneys, by installing it on top of FGD ((Flue Gas Desulfurization) at the plant.
Further, if only EMEs are installed in existing environmental facilities, fine dust and ultrafine dust from thermal power plants can be reduced to less than 0.5 mg/Nm3.
This is the lowest level in the world, which is only 4 percent of the 12mg/Nm3 allowed by the Ministry of Environment and 10 percent of the 5mg/Nm3 emission standard in the metropolitan area.
Doosan Heavy has successfully completed the test by installing a life-size pilot EME that can be applied to the country's standard coal-fired thermal power plants at its Changwon plant.
In addition, it has finished designing a 500MW EME commercialization and is planning to prove it to a standard coal-fired thermal power plant, along with major power generators.
