Abstract:
 NO emission characteristics during pulverized coal combustion in an O2/CO2 atmosphere were studied
for micro-pulverized coal(0—20,?m),large-size coal(70—100,?m)and mixed-size coal of the above two coals
with an equal mass fraction.The relationship between oxygen-containing functional groups and NO emission was
analyzed by FTIR analysis.Results show that the NO emission curve along the furnace length was displayed as “Mtype” in coal devolatilization and char burning processes.With the increase of the inlet oxygen mole fraction,the
NO concentration increases rapidly and reaches a peak in a shorter time.While the NO concentration near the furnace outlet does not shown the same trend.The coal size has a great effect on the NO emission.The peak of “Mtype” curve and the location where the peak occurs change with the coal size.In the coal burning process,the
oxygen-containing functional groups change with the inlet oxygen mole fraction.A lower NO emission was observed when more oxygen-containing functional groups were generated.
