In recent years, low air ratio high temperature combustion has become the mainstream in waste stoker incinerators in order to improve boiler efficiencies, while NOx generation due to high temperature in the furnace has become a new problem. In this study, the NOx generation behavior derived from nitrogen in char was evaluated by simulating the char combustion area in the incinerator in the combustion experiment of the biomass char sample by DTF (Drop tube Furnace) using the combustion atmosphere as a parameter. In particular, we focused on the effects of high-concentration H2O and CO2 concentrations due to exhaust gas recirculation and confirmed that H2O contributes to the reduction of NOx emissions.
