ABSTRACT

 

A Power plant situated in the middle of a mega city affects drastically towards the level of different pollutants. The present work focuses on the impact assessment of main air pollutants emitted by Pragati Power Plant, Delhi (India) within a radius of 10 km. Simulations are carried out by using Industrial Source Complex Short Term (ISCST3) model for all seasons. NOx is considered to be the main pollutant emitted by the power station, as it is gas based power plant. The meteorological variables as wind speed; wind direction and ambient temperature data recorded by Indian Meteorological Department (IMD) for 2011-12 have been used for concentration computations. For this study period Westerly winds are found to be dominating. The maximum concentration 15.484 g/m3 of NOx is found to be at 1 Km. downwind towards West, in which the wind is also found to be dominated.
