Prediction of incremental concentration of air pollutant is done for both the Boilers and DG set working independently, under the worst case of emissions.
E. Air estimation : Air quality estimation is done with Plausibility approach using Gaussian Plume Model. Prediction of air quality under given emission conditions is needed to check whether the actual concentrations of PM2.5 & PM10, SO2 and NOx shall not be exceeding the Ambient Air Quality Standards prescribed by CPCB. E.1. Plausibility approach using Gaussian Plume Model ( GPM )
Prediction of pollutant concentrations can be made by suitable air quality model. Application of such model require in addition to emission data, proper meteorological data ie. Simultaneous wind speed, direction and cloudiness data
Under such condition it is possible to use plausibility approach model to obtain maximum possible impact from the unit. This impact level can be used in the design and also for setting operating limits.
Input parameters are so chosen by taking into consideration their plausibility of occurrence such that the model gives the maximum impact.
Steps : a. Determination of critical wind speed – Wind speed affects the GLC in two ways in the model, one directly and other through plume rise. One hour average GLC values are determined for standard distances ( 100 m.to 20 km ), for six stability classes ( A- F ).
From these values Critical wind speeds for each stability classes are determined which gives maximum concentration value for that wind speed.
b. Use of critical wind speeds to determination of max. GLC- Based on the maximum one hour GLC values estimated with these critical wind speed for six stability classes and selecting worst condition, ie. assuming plausibility of occurrence of different stability conditions in hours, during day time and night time, 24 hour average values are worked out. c. This value represents the maximum under worst condition which shall not exceed at
any time.
E.2. One hour average Centre line GLC of pollutant :
Gaussian Plume Model : ( GPM ) For determining one hour average concentration values Gaussian Plume Model (GPM ) is used.
The model is based on four basic assumptions:
The solution is time variant;
Wind speed is not a function of position;
Diffusivities are not a function of position
Diffusion in downwind direction is insignificant;
Despite these assumptions GPM is still a workhorse for dispersion calculations.
One hour average pollutant concentration [ Centre line ground level ] = C x, 0, 0 C x, 0, 0 = [ Q / ( Π x SY x SZ x UH ) ] * [ Exp (– H2 / 2 x SZ2 ]
where Q = Emission Rate of Pollutant in μg / sec UH = Ave. wind speed in m / sec at H SY = Standard Deviation of plume conc. in Horizontal direction in m. SZ = Standard Deviation of plume conc. in Vertical direction in m H = Effective Stack Height in m. = h + ∆ h. h = Physical stack height in m. ∆ h = Plume Rise in m.
E.3. Plume Rise :
The flue gas pressure for boiler is low and flue gas velocity is also low, hence the plume rise
for the stack of 8 TPH boiler and 6 Lakh Kcal/hr boiler stack are negligible. Hence not
considered for model.
E.4. Averaging time correction :
Averaging time correction factor for converting one hour concentration to 24 hour = 0.40
24 hr average = [ Sum of one Hr ave. concentration / 24 ] x 0.4

From the above estimation of GLC for PM10 , PM2.5 , NO2 & SO2 conc. from the emissions of
the Boilers working or only DG sets working, following conclusion are drawn :
1. Air pollution estimation is done for worst condition with APC working and no plume rise
existing. Total concentration is worked out by adding ambient air quality value with
incremental concentration contributed by proposed working of boilers and DG set.
2. GLC of PM10 for villages in 10 km radius -- From the tables above, it is seen that the
under worst case of absence of plume rise the total concentration of PM10 from the
Plant emission is in the range of 51.05 to 92.19 ug/m3, All these values are less than
the AAQS for PM10 of 100 ug/m3 .
3. GLC of PM2.5 for villages in 10 km radius -- From the tables above, it is seen that the
under worst case of absence of plume rise,the total concentration of PM2.5 from the
Plant emission is in the range of 27.11 to 53.81 ug/m3. All these values are less than the
AAQS for PM2.5 of 60 ug/m3 .
4. GLC of SO2 for villages in 10 km radius -- From the tables above, it is seen that the under
worst case of plume rise is absent the total concentration of SO2 from the Plant emission is
in the range of 23.64 to 75.47 ug/m3 . All these values are less than the AAQS for SO2 of
80 ug/m3 .
5. GLC of NOx for villages in 10 km radius – From the tables above, it is seen that the under
worst case of plume rise is absent the total concentration of NO2 from the Plant emission is
in the range of 24.01 to 56.18 ug/m3 . All these values are less than the AAQS for NO2 of
80 ug/m3 .
6. Air pollution control equipment in the form of multicyclone followed by bag filter with
particulate matter removal efficiency of ≥ 90 % shall be installed to restrict particulate
emissions from coal fired units.
Therefore there shall not be any adverse impact on air environment due to the emissions
from the industry.
