气化炉高铬砖的磨损及耐火材料寿命延长措施

时间:2020-02-11 11:41 作者:耐火材料生产厂家点击:次

气化炉内高铬砖腐蚀和磨损的原因

GE水煤浆气化炉,其壳体(包括燃烧室与激冷室)主体及锻件材质均采用SA387Grade11ClasS2,经过正火+回火精炼和真空脱气处理,在500℃以下具有良好的高温强度、抗氧化性、抗硫化物腐蚀性。其中,核心设备——气化炉燃烧室分为三部分:上部为拱顶,(由内向外)采用高铬砖和铬刚玉浇注料、纤维涂抹料(可压缩料)砌筑,拱顶高铬砖设计使用寿命一般为15000h;中部为筒体,(由内向外)采用高铬砖和铬刚玉砖、隔热砖、纤维涂抹料(可压缩料)砌筑,筒体高铬砖设计使用寿命一般为12000h;下部为锥底和渣口,(由内向外)采用高铬砖和铬刚玉浇注料砌筑,锥底高铬砖设计使用寿命一般为6500h,渣口高铬砖设计使用寿命一般为4000h。

气化炉燃烧室设计内衬4层耐火材料——高铬砖、铬刚玉砖、隔热砖、纤维涂抹料(可压缩料),其作用分别为:高铬砖使用Cr90砖(Cr2O3),为高密度高铬砖,能够保护绝热耐火材料免于渣蚀、氢蚀及火焰损害;气化炉支撑衬里层为高密度低铬高铝材料(Cr2O3与Al2O3),即铬刚玉砖,主要作用为支撑拱顶砖,可大大减轻气化炉的重量;隔热砖(保温层)为氧化铝空心球砖(铁含量低),可有效降低金属壳体的温度,提高壳体耐CO腐蚀的能力;纤维涂抹料(可压缩料)是由碎耐火纤维制成的绝热材料(一些设计中也使用25.4mm厚的耐火毡),可在耐火砖被加热发生膨胀的情况下被压缩,对壳体起到绝热保护的作用。

气化炉高负荷运行,进入气化炉的煤浆流量和氧气流量大,渣量也必然大,势必加速高铬砖的冲刷和烧蚀,对高铬砖的使用寿命颇有影响。
