Modeling N2O/NO formation and reduction during combustion of char

The method of combusting coal in a fluidized bed combustor has many advantages. Due to the low combustion temperature, the emission of NOx is low compared to conventional combustion techniques, because at these low temperatures the formation of NOx from N2 and 02 from the fluidizing air (thermal NOx) and NOx formation through oxidation of char bound nitrogen (fuel NOx), is less pronounced. Furthermore it is possible to reduce the emissions of S02 and S03 in the temperature range of a fluidized bed combustor by means of limestone addition to the bed
