Combustion of coal as a source of N2O emission - …

Coal combustion is examined as a source of nitrous oxide pollution and a review of relevant research is presented. The role N 2 O plays in global warming and in stratospheric ozone depletion is explained and comparisons are made between N 2 O and other greenhouse gases. A balance of known N 2 O sources and sinks is also reported. Nitrous oxide emerges as a powerful and long-lived greenhouse

The effect of biomass pyrolysis gas reburning on N2O

The fossil fuel consumption and pollutant emissions in a coal fired fluidized bed boiler could be reduced by biomass pyrolysis gas reburning. The influence of three kinds of biomass pyrolysis gases on the emission of N2O in a laboratory scale fluidized bed was investigated using …

EPA Workshop On N2o Emission From Combustion …

This figure suggests a con- stant fractional conversion of fuel bound nitrogen to N20, which implies that coal- and heavy-oil-fired boilers are the most important N20 emission sources. This trend further supports the analysis which defined large industrial and utility boilers as the largest contributors to anthropo- genic N2O emissions.

In SNCR systems, a reagent is injected into the flue gas in the furnace within an appropriate temperature window. Emissions of NOx can be reduced by 30% to 50%. The NOx and reagent (ammonia or urea) react to form nitrogen and water. A typical SNCR system consists of reagent storage, multi-level reagent-injection equipment, and associated control instrumentation.

Main sources of nitrous oxide emissions What's Your …

Nitrous oxide is a by-product of fuel combustion in mobile and stationary sources. When any fossil fuel is burnt, part of the nitrogen that is in the fuel and surrounding air gets oxidized creating nitrous oxide emissions. The majority of stationary emissions come from coal fired power plants.
