水煤浆气化炉炉合成气中CO2与CH4必须是反逆趋势吗
Reply #42017-03-04
在在线分析分析仪表为质谱仪,进口Primama Proブランド。 但工艺认为CO2含量有升高趋势时,代表炉温升高了,CH4也应该相应有下降趋势,但分析仪有时会有这两个含量同时上升下降的情况,令人费解。 仪表运维人员也反复进行了标定,通标准气,得出结论为分析仪准确无误。 请教各位同行什么原因会造成此现象。

一般来说气流床气化(水煤浆和干煤粉)都是这样的趋势。CO炉含量随着炉温升高而升高,甲烷随着炉温下降而上升。所以一般来说CO炉含量和甲烷含量用作来指导炉温调节的指标。但是CO炉含量和甲烷含量同时上升或者下降这样的的情况比较少见,监测仪表的原因可能性较大,但是也不能排除工艺自身原因的原因。不知道楼主烧嘴的压差(煤浆与气化炉压差、氧气和气化炉压差)和氧煤比是多少?是否正常?是否是单台炉炉是这样炉全部都是这样,如果是单台炉这样的话,将运行指标和正常炉炉对比一下有什么不同,有助于找到原因。

煤浆与气化炉压差CO炉-0.1至、氧气和气化炉压差O2--O.0、氧煤比444-466。一台炉炉有问题另一台炉,质谱仪为一台,切换流量使用用。

煤浆压差似乎有点偏低、氧气压差似乎有点偏高、氧煤比正常。这个烧嘴用了多久了?
