Nitrogen Oxides (NOx) Emission from Fuels
Emission of Nitrogen Oxides - NOx - with combustion of fuels like oil, coal, propane and more.
Emission of Nitrogen Oxides - NOx - when burning different types of fuels:
|Fuel||Emission of NOx 1) |
(10-3 kgNOx / kgfuel)
|Wood, Birch 20% moisture content||0.7|
1) note that the emission varies widely depending on application temperatures and air/fuel ratios. In general - higher combustion temperature and higher air/fuel ratios increases NOx emissions.
2) zero emission for hydrogen is a theoretically value. In practice hydrogen burned in air produces more NOx than natural gas due to the high flame speed
3) catalytic systems common on most modern vehicles reduces NOx
NOx emissions contributes to eutrophication, acidification and the formation of ground-level ozone.
Boiler house topics, fuels like oil, gas, coal, wood - chimneys, safety valves, tanks - combustion efficiency.
Climate, meteorology, sun, wind and environmental related engineering resources.
Fuels and Chemicals - Autoignition Temperatures
Autoignition points for fuels and chemicals like butane, coke, hydrogen, petroleum and more.
Optimal Combustion Processes - Fuel vs. Excess Air
Stable and efficient combustion requires correct mixture of fuels and oxygen.
