Soot and dust control
Soot and dust refers to impure carbon particles and cinders. The filter fabric in the bag filter removes soot and dust from the exhaust.
Dioxin control
Dioxin is a generic term given to polychlorinated dibenzo-para-dioxins, polychlorinated dibenzo furans and coplanar polychlorinated biphenyls.
Dioxin emissions are suppressed by burning waste at a high temperature. The cooling tower quickly cools the exhaust to prevent recomposition. The bag filter removes them in addition to soot and dust with the use of filter fabric.
Mercury control
Mercury is a highly volatile metal toxic to humans. The bag filter adsorbs it on active carbon. In the fume-cleaning system, mercury is immobilized using a liquid chelate for removal.
Hydrogen chloride and SOx control
Hydrogen chloride and sulfur oxide (SOx) are air pollutants that cause acid rain.
For their removal, the bag filter blows slaked lime in, while the fume-cleaning system causes a reaction with a sodium hydroxide solution.
NOx control
Nitrogen oxide (NOx) is an air pollutant that brings about photochemical smog and acid rain. It is reacted with ammonia to decompose it with the use of a function of the catalyst.
