MODELLING AIR POLLUTION WITH PARTICULAR REFERENCE TO THE THERMAL POWER PLANTS

Gopal Chandra Bera

Abstract

Thermal Power generation is a major source of electrical energy in our country. The emissions from The Power e.g. S0x, NOx, Fly - ash etc. are pollutants to the air which cause several hazards to the life of inhabitants of the locality and the plants as well. For assessing the quality of air in the adjacent to the pollutant source and its proper monitoring, several mathematical models have been developed. Proper testing of the mathematical models with experimental data and necessary developments of the model is very much essential for better pollution control management. This report deals with the application of Gaussian Plume model for the study of air pollution in and around Kolaghat Thermal Power Plant (KTPP) in West Bengal.The study includes the effect of surrounding temperature in different seasons, wind velocity, stick height and some index parameters of the model. The model identifies a critical zone in and around KTPP, which may be affected by the pollutants emitted from the plant. The study shows that the theoretical predictions according to the model fit well with the experimental data to a good extent.
