Pollution and Environmental Damage
- Nitrogen
- Sulphur Dioxide
- Poor air quality & Smog
- Acid rain
Smog
- Forest damage
- Depletion of Ozone layer
- GREENHOUSE EFFECT
NOx
SOx
POLLUTANTS


CARBON DIOXIDE
Produced by combustion of fossil
fuel/coal/oil/gas
 C + O2 = CO2 ….carbon fuel
 CH4 + 2O2 = CO2 + 2H2O …..gas fuel
 CO2 absorbs infrared/heat radiation/sun
 Melts polar ice caps
Smog
 Stoichiometric burner parameters
 - flue gas O2 least / CO2 max
 - efficient burners low excess air / least CO2

OXIDES SULPHUR
Burning of fuel sulphur
S + O2 = SO2 ….further oxidation
2SO2 + O2 = 2SO3 ….moisture in air
SO3 + H2O = H2SO
PRIMARY AIR POLLUTANT
 SECONDARY AIR POLLUTANT
POLLUTANTS

CARBON MONOXIDE
 - Lack of oxygen during combustion
 - Flame is chilled

- Fatal Gas

NITROGEN OXIDES NOx
- high 0 C of combustion process
- in precombustion/combustion and
post flame region
- combustion air Nitrogen and natural
and organic Nitrogen in fuel
NO + NO2

SMOKE
- Excess fuel
- Incomplete combustion
- flame impingement
- Smoke .. Carbom particles….into Air
- Fouling of boiler surface
- reduce efficiency
POLLUTANTS

NOISE

- Damaged hearing & Stress related

- Unwanted sound

- Disrupt working efficiency !!
