POLLUTION – Global IssuePOLLUTION – Global Issue
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
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 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
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 SMOKE - Excess fuel - Incomplete combustion - flame impingement - Smoke .. Carbom particles….into Air - Fouling of boiler surface - reduce efficiency
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 NOISE
- Damaged hearing & Stress related
- Unwanted sound
- Disrupt working efficiency !!
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
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
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
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
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
