Assessment of Atmospheric Emission Pollutants from the Thermal Power Plant: Case of Oyom-Abang Yaound?-Cameroon

In the context of obtaining a real overview on the quantities of pollutants emitted in the thermal power plants of the engines WARTSILA VASA 18V32LN turbo alternators of 6.556 MW and running on heavy fuel oil, our participation is made on two plan. All First, the estimation of emissions by volumetric meter of fuel and the estimation of emissions by level of activities has this we have improved and associated equations to estimate of emissions. Throughout the years 2009-2010-2011 the following variations of each engine have a consumption of 22921, 3 Kg for Motor1, 25035, 6 Kg for Motor2 and 25467, 17 Kg for Motor3. With regard to the emissions of pollutants, for the first engine Motor1 777, 2kg Sulfur Oxides, 1390, 5 kg of Carbon Monoxide, 2121, 8 kg Nitrogen Oxides, 498, 9 kg of Particulate matter 2.5m and 1m in diameter and 1995, 9 kg of particulate matter to 1m in diameter. For the second engine 844, 1kg Sulfur Oxides, 1518, 8kg of Carbon Monoxide, 2317, 5kg Nitrogen Oxides, 912, 3 kg of particulate matter 2.5m and 1m in diameter and 3649, 3 kg of particulate matter to 10m diameter. For the third engine 858, 6 kg Sulfur Oxides, 1545 kg of CO, 2357, 5 Kg Nitrogen Oxides, 928, 1 kg of particulate matter 2.5m and 1m in diameter and 3712, 3 kg of particulate matter to 10m in diameter. Of these results, it follows that the Engine 2 and 3 of the Central Thermal presents a huge pollution in particulate materials.
