摘　　要：通过热轧加热炉烧嘴热态试验,分析了天然气掺烧条件下烧嘴流量特性的变化规律,结果表明:等热值条件下,随着天然气掺烧比例的增大,混合煤气密度增加,调焰烧嘴稳定燃烧时煤气压力提高;在天然气比例为22%时,煤气压力提高约20%。Based on the thermal tests of hot rolling heating furnace burner , the paper analyzed the change in flow characteristics of natural gas mixed in burner firing conditions .The results showed that ：under the same heating value circumstances ,both the density of mixed gas burner flame and stable com-bustion gas pressure would rise with the gas mixing proportion increasing ,and that the gas pressure in-creased about 20% w hen the proportion of natural gas is 22% .
