针对浮法玻璃熔窑火焰空间建立模型并进行了数值模拟，在保证热值相同的前提下，对比研究了重油燃烧及将石油焦部分替代重油燃烧时的流场分布特征。结果表明，石油焦部分代替重油燃烧后，两种燃料可很好地混合燃烧，窑炉内温度制度基本不受影响；石油焦着火时间比重油长，两种燃料混合燃烧时平均着火点滞后于仅使用重油时，且燃烧路径更长，燃烧时产生了大量CO，整个火焰空间及烟气出口处NOx的平均排放量与仅使用重油相比降低了30.02%，NOx减排效果明显。

The numerical simulation in the combustion space of a float glass furnace was carried out. Under the premise of ensuring the same fuel calorific value, the flow field distribution characteristic of heavy oil combustion and co-combustion of petroleum coke and heavy oil was studied. The results showed that the two fuels can co-fire well, and the temperature system in the furnace was basically unaffected. In contrast, the petroleum coke's ignition time was longer than that of the heavy oil, so the average ignition point of the fuel during co-combustion lags behind when only heavy oil was used and the flame was longer. When the fuel was co-firing, more O2 was needed, the combustion was not enough, and a large amount of CO was generated. Finally, the total NOx emission at the flue gas outlet was reduced by 30.02% compared with the case using heavy oil only, and the NOx emission reduction effect was obvious.
