假定100m3鼓风为基准,其鼓风湿度为f=2.0%,计算炉缸煤气成份的百分含量?(以100m3鼓风计算)
正确答案:
由反应式2C焦+O2+(79/21)N2=2CO+(79/21)N2
得一个O2将生成两个CO
CO=[(100-f)×0.21+0.5×f]×2=[(100―2)×0.21+0.5×2]×2=43.16m3
N2=(100―f)×0.79=98×0.79=77.42m3
H2=100×2%=2.00m3
∴CO+H2+N2=122.58m3
∵CO=43.16/122.58×100%=35.21%
N2=77.42/122.58×100%=63.16%
H2=2/122.58×100%=1.63%
炉缸煤气成份CO为35.21%,N2为63.16%,H2为1.63%。
