 Coal is composed primarily of carbon along with variable quantities of other elements, chiefly hydrogen,,sulfur,oxygen, and nitrogen.

Of the region, depending on terrain and weather conditions, the effect may spread to hundreds of kilometers.

Perhaps most importantly, uranium are released and spread around, in lignite combustion

Flue Gas Desulfurization – FSD Desulphurizatio n unit can hold 95% of SO2 gas. However, the FSD is just to keep the sulfur

 Electrostatic filters % rate help keep dust and ashes

 Selective catalytic reduction (SCR) technology is a proven and effective method to reduce nitrogen oxides (NOx) emissions from coal-fired power plants.  How does selective catalytic reduction technology work? During the combustion process, the nitrogen that is present naturally in the coal, and the nitrogen and oxygen present in the combustion air combine to form NOx. Prior to being released to the atmosphere, the exhaust gas is passed through a large catalyst where the NOx reacts with the catalyst and anhydrous ammonia and is converted to nitrogen and water. Selective catalytic reduction removes between 80 and 90 percent of the NOx that is in the exhaust gas of a coal- fired power plant.  Selective catalytic reduction (SCR) technology is a proven and effective method to reduce nitrogen oxides (NOx) emissions from coal-fired power plants.  How does selective catalytic reduction technology work?
