The paper presents the results of experimental investigations on NOx (NO + NO2) formation during LPG combustion in a fluidized bed of sand. Experiments were carried out by adding NO to the gases at different concentrations. NO conversion to NO2 was examined. It was found out that NO is the precursor of NO2 but the relationship between NO and NO2 concentrations is nonlinear and there is a discrepancy in the balance of combined N.
