| Abstract: | Experiments have been carried out on a laboratory-scale fluidized bed boiler with a capacity of 1 t/h and a small-scale fluidized bed reactor to investigate the emissions of N2O at different bed temperatures and heights over the bed furnace. An investigation has also been made on the sampling technique. The results show that a higher bed temperature will reduce the emission of N2O but increase the emission of NO. It has also been found that N2O and NO concentration change only a little from the upper part of the bed to the exit of the furnace. The investigation on the sampling technique also shows that if the sample gas can be analyzed in a short interval, say within 30 minutes, and without being treated and stored, there is no clear difference between direct sampling and sampling after removal of SO2 and H2O. |
