The fuel lean reburning system is considered for reducing NO_X emission by using numerical approach. Liquefied Petroleum Gas (LPG) is used as the main and reburn fuel. The fuel lean reburning system has to operate in a fuel lean condition in order to achieve complete combustion, since additional air is not used anymore in fuel lean reburn technology. The goal of this work is to obtain the most optimal combustion system by employing the fuel lean reburning system to reduce pollutions. Furthermore, there are very few studies that have focused on how the reburning process is affected by changes in the flow field that are induced by combustion. It is important to study the effect of the combustion condition on the reburning process in order to control fuel lean reburning. The results show that the fuel lean reburning method leads to 45% NO_X reduction by using 0.13 of the reburn fuel fraction and by achieving complete combustion without any additional oxidizer. Furthermore, the importance of the recirculation flow into the furnace region is verified by the measuring and predicting methods.
