Determination and dispersion of pollutants from different fuel types used in brick kilns by using Gaussian’s plume model

ABSTRACT

The present study was conducted to compare the concentration of pollutants and their level of dispersion in the atmosphere from the plume of brick kilns using different types of fuels. For this purpose, two brick kilns were selected based on their fuel type. One type of fuel was good quality coal (F1) and the other was low-quality coal mixed with wood (F2). The air emissions data illustrated that carbon monoxide concentration was more (108 ± 0.90 ppm) in the plume of F1 than in the plume of F2 (82 ± 0.98 ppm) and sulfur dioxide was more (1955 ± 3.76 ppm) in the plume of F2 than in the plume of F1 (6 ± 0.07 ppm). The Gaussian plume model showed that plume from good quality coal as fuel (F1) disperses 0.7 ± 0.01 km horizontally and 4 ± 0.03 km vertically whereas the plume from low-quality coal mixed with wood (F2) disperse 1 ± 0.01 km horizontally and 2 ± 0.02 km vertically. Pearson correlation also showed a significant (p < 0.05) difference between both fuel types. These high concentrations can have negative impacts on the atmospheric environment as well as community health.
