Stack Height/Limits of Thermal Power Plants | ||
Generation Capacity | Recommended Stack Height for Optimum Dispersion of Sulphur Dioxide | |
500MW and above | 275 | |
200 MW/210 MW and above to less than 500 MW | 220 | |
Less than 200 MW/210 MW | H=14 (Q) 0.3 where Q is emission rate of SO2 in kg/hr, and H is stack height in metres. | |
