  4. POWER PLANT FLOW CHART

  5. Coal-firedpowerplants

  6. How is Coal Converted to Electricity?

  7. ABOUT COAL • Coal is composed primarily of carbonalong with variable quantities of other elements, chiefly hydrogen, ,sulfur,oxygen, and nitrogen.

  12. The effects of the flue gases and wasteproducts • IF YOU USE ANY FILTERS , 100-megawatt coal-fired thermal power plant pollutant effects are seen in the table Source: Environmental Problems Foundation of Turkey

  13. SO2 and NOX gases are primarily responsible for the formation of acid rain! Of the region, depending on terrain and weather conditions, the effect may spread to hundreds of kilometers.

  14. Pile of ashes spread radioactivity to the environment Perhaps most importantly, uranium are released and spread around, in lignite combustion

  15. PreventionOpportunities

  16. Other substances emitted from the stacks, areflueash(particulate matter – PM) • Electrostaticfilters95 - 99% rate help keep dust and ashes

  17. Selectivecatalyticreduction • 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.
