Air polluting materials such as NOx, dioxin, SOx, dust and VOC, exhausted from boilers and vehicles that burn fossil fuels and convert them into energy, are exposed to the air, and give seriously harm effects to the ecosystem of the mankind, animals and plants.
The denitrification facility eliminates the NOx materials, generated from combustion of nitrogen component in fuels and air. Because improvement of the combustion conditions has a technical limitation in the reduction efficiency and it requires additional treatment facilities after combustion, the most reliable selective catalytic reduction (SCR) system occupies most of the NOx materials elimination markets.
The desulfurization facility eliminates the SOx materials, generated by reaction between the sulfate components and the oxygen in process of combustion of fuels. It is obligatory to install desulfurization facilities for large-scaled power plants and incineration facilities in Korea and other overseas countries. Installation of desulfurization facilities for the medium-sized boilers has not been active, but the facilities have an infinite marketing potential in the future owing to localization of the relevant technology and the economical prices.
