Finding resilient refractory materials for slagging gasification systems have the potential to reduce costs and improve the overall plant availability by extending the service life. In this study, different refractory materials were evaluated under slagging gasification conditions. Refractory probes were continuously exposed for up to 27 h in an atmospheric, oxygen blown, entrained flow gasifier fired with a mixture of bark and peat powder. Slag infiltration depth and microstructure were studied using SEM EDS. Crystalline phases were identified with powder XRD. Increased levels of Al, originating from refractory materials, were seen in all slags. The fused cast materials were least affected, even though dissolution and slag penetration could still be observed. Thermodynamic equilibrium calculations were done for mixtures of refractory and slag, from which phase assemblages were predicted and viscosities for the liquid parts were estimated.

寻找用于排渣气化系统的弹性耐火材料有可能通过延长使用寿命来降低成本并提高工厂的整体利用率。在这项研究中，在炉渣气化条件下评估了不同的耐火材料。耐火材料探针在大气中吹氧，夹带流化气炉中连续暴露长达27小时，该气化炉用树皮和泥炭粉末的混合物烧制。用SEM EDS研究了炉渣的浸润深度和显微组织。用粉末XRD鉴定结晶相。在所有炉渣中都发现了源自耐火材料的铝含量增加。尽管仍然可以观察到溶解和熔渣渗透，但熔铸材料受到的影响最小。对耐火材料和矿渣的混合物进行了热力学平衡计算，
