摘　　要：利用改进的Le Chatlier公式,对煤气湿度为40 g/m^3、80 g/m^3、120 g/m^3、170 g/m^3的八组发生炉煤气计算样本进行爆炸极限的理论计算,发现在干煤气成分不变的情况下,随着发生炉煤气湿度的增加,煤气爆炸上限和下限均有不同程度的提高,但煤气爆炸极限范围逐渐收窄。同时指出由于应用湿度范围内(32~178g/m3)的发生炉煤气的爆炸极限变化较小,在发生炉煤气的实际应用过程中,煤气湿度对爆炸极限的影响可以忽略不计。Using the improved Le Chatlier formula,explosion limit theoretical calculation was carried out on eight groups of producer gas samples whose humidity are40g/m3,80g/m3,120g/m3and170g/m3,respectively,and it was found that with dry gas composition unchanged,the upper and lower gas explosion limits are increased with increase of gas humidity,but gas explosion limit range are gradually narrowing.At the same time,it is pointed out that as the change of explosion limit of the producer gas in the humidity range of32~178g/m3is small,the effect of gas humidity on explosion limit is negligible in practical application of producer gas.
