摘要

A study of the nitrogen oxides (NOx) emission and combustion process in a gas-fired regenerative, high temperature, low emission industrial furnace has been carried out numerically. The effect of two additives, methanol (CH_3OH) and hydrogen peroxide (H_2O_2), to fuel on the NOx emission has been studied. A moment closure method with the assumed P probability density function (PDF) for mixture fraction is used in the present work to model the turbulent non-premixed combustion process in the furnace. The combustion model is based on the assumption of instantaneous full chemical equilibrium. The results showed that CH_3OH is effective in the reduction of NOx in a regenerative industrial furnace. However, H_2O_2 has no significant effect on the NOx emission.
