LIMIT OF EMISSION ,STACK HEIGHT FOR THERMAL POWER PLANT


EIA studies are very big subject itself encompasses number of studies in between to reach a conclusion. Therefore without going to a detail study comprehensive summary has been given for construction manpower to understand about enviorment while working at site. Now we are mentioning limit allowed one by one with the help of MOEF rules and acts and EIA studies submitted by consultant of the owners.
MOEF ( Ministry of enviroment and forest) vide Notification of 19th May 1993 issued as amendment
rules to environment ( protection) Act 1986. The particulate matter emission limits for thermal power stations are as follows.
Generation capacity 62.5 MW or more                                                  150mg/Nm3
Generation capacity < 62.5 MW and commissioned before 1.1.82        350mg/Nm3
Units located in protected place area irrespective of  size                      150mg/Nm3.
Generation Capacity

Stack Height (Metres)




500 MW and above




275




200 MW/210 MW and above to less than 500 MW

Less than 200 MW/210 MW




220
H=14 (Q)0. 3
where Q is emission rate of SO2, in Kg/h, and H is Stack height in metres




The above parameters have been fixed by MOEF for Stacks . Wherever the stacks height calculation is necessary  above calculation will be guiding factor.
