Stack Height (Limit) criteria for Coal based Thermal Power Plants have been developed in India, based on proper dispersion of SO2 emissions from TPPs in Ambient Air.
For TPPs having Boiler Capacity more than 500 MW and above, space provision for installing FGD has been recommended.
TPPs having Stack Height in Mtrs
Capacity (MW)
1. < 200/210 Height in Mtrs= 14Q0.3
2. 200/210 to < 500 220 Mtrs
3. 500 MW & above 275 Mtrs
Q is SO2 Emission rate from stack in Kg/Hr
There are some requirements for TPPs sanctioned earlier to 1 June 1994 with regards to stack height.
Such TPPs may not be required to increase the existing height subject to the following conditions:-
1. The ambient SOx & Nox concentration levels is less than 1/3 th of the prescribed air quality standards for SOx & NOx for the Concerned Area.
2. Such TPPs shall install adequate no.of Air quality monitoring stations in & around the Power plant area. These Monitoring station be selected in consultation with SPCB/CPCB.
