为探究工业合成气(主要成分为H2和CO)的体积分数及惰化作用下,其最小点火能变化特征,首先,选取CH4气体样品,利用最小点火能测试装置确定试验系统的敏感条件;然后,基于系统敏感条件,测定不含惰性气体N2系统中添加不同比例的H2与CO混合物的最小点火能;最后,测定N2稀释作用下气体混合物的最小点火能.研究结果表明:不含惰性气体的H2与CO合成气中,H2体积分数低于25％时,其对合成气的敏感体积分数值影响较大;含惰性气体N2的H2与CO合成气中,燃料体积分数大于40％时,惰化作用效果显著;含惰性气体N2气体的H2与CO合成气中,燃料体积分数小于40％时,系统最小点火能值的贡献主要取决于H2所占体积分数.
