在气化装置开车以后，该公司不断拓宽气化原料煤的指标范围，在590天不间断运行期间，先后使用过 20余种煤。其中煤质灰熔点最低1140℃，最高超1350℃，灰分含量在8%～14%波动，气化炉始终稳定 运行。 "这些实际运行效果的获得主要得益于航天工程在核心装备和工艺流程上持续不断的研发创新。"航天长 征常务副总经理朱玉营指出，在核心装备方面，该项目使用的半废锅航天炉，在废锅段采用熔渣冷幕墙 技术和在线振打清灰技术，解决了废锅积灰堵渣和蒸汽衰减的行业难题;在激冷段采用自研的雾化激冷 和溢流结构，不仅结构简单，大大减少了定检维修工作量，还解决了因煤质和负荷变化引起激冷室液位 不稳定的另一行业难题。在工艺流程上，该项目首创了新型三合一式的合成气分离洗涤塔，并就近布置 在气化框架内，该新型流程不仅投资低、占地小，而且延长了合成气管道使用寿命、降低了系统压降。 在节能降碳方面，该项目也进行了多项技术升级：半废锅气化炉通过废锅回收合成气在高温区的显热， 产出高品位蒸汽，实现能量高效稳定的梯级利用;粗合成气经废锅换热后经激冷水带走热量较少，减少 渣水系统循环水的热量损失;采用三级闪蒸代替两级闪蒸，增加低压闪蒸罐和低闪汽提塔， ...
