The subject of the research was the influence of N2O on propane combustion in a fluidized bed reactor with active and chemically inert beds. It was determined that CaO has a significant influence on shifting the area in which the reaction is most intensive deeper into the bed and on the combustion result. It was also observed that adding nitrous oxide causes a decrease in VOC and CO concentration in exhaust gas. It was established that N2O, when added, is the determining factor of NOx creation, which takes place in a similar manner as via the prompt mechanism.
