Pollution and Environmental Damage - Nitrogen - Sulphur Dioxide - Poor air quality & Smog - Acid rain - Forest damage - Depletion of Ozone layer - GREENHOUSE EFFECT

Smog

NOx SOx

POLLUTANTSPOLLUTANTS

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 Stoichiometric burner parameters - flue gas O2 least / CO2 max

- efficient burners low excess air / least CO2

Smog

POLLUTANTSPOLLUTANTS 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

absorbs infrared/heat radiation/sun Melts polar ice caps Stoichiometric burner parameters - flue gas O2 least / CO2 max - efficient burners low excess air / least CO2

POLLUTANTSPOLLUTANTS CARBON MONOXIDE - Lack of oxygen during combustion - Flame is chilled

- Fatal Gas

T Series Air Staging


POLLUTANTSPOLLUTANTS 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


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


POLLUTANTSPOLLUTANTS NOISE

- Damaged hearing & Stress related

- Unwanted sound

- Disrupt working efficiency !!


SOLUTIONSSOLUTIONS NOx Reduction - Furnace capacity MW/m3

- Temp of Furnace wall - Furnace dimension ratio 3.5:1 - Preheated Air & Humidity SOLUTIONS - External flue gas circulation - Air & fuel Staging ……Dunphy’s - Water & steam injection


SOLUTIONSSOLUTIONS BURNER DESIGNS - Gun Type - Rotary cup - Co-axial ….fulfills all req of combustion ….controlled & uniform air ….higher efficiency lower pollution ….quiet & low noise levels
