西门子GSP气化技术特点 Features of Siemens GSP Technology
技术特色 Features
煤种适应性强：无需考虑煤的成浆性， 从较差的褐煤、次烟煤、烟煤、无烟煤 到石油焦均可使用 High adaptability 技术指标优越：碳转化率高，合成气中有效成分CO+H2高，冷煤气效率高 Performance: high carbon conversion, high content of CO+H2, high efficiency 氧耗低：可降低配套空分装置投资和运行费用 Low Oxygen consumption: reduce capex 烧嘴寿命长 Long life of burner 气化温度可以较高,能气化高灰熔点的煤,增强了煤种适应性 High gasification temperature, reinforce coal adaptability 气化炉无运转部件，设备寿命长，维护量小，连续运行周期长，在线率高 No rotating components, long life, min. maintenance, high availability 开、停车操作方便，且时间短 Convenient startup and shut down 控制系统简单、节省投资、便于操作 Simple control system, cost saving, easy operation 维护简单方便、便于接入全厂控制系统 Easy maintenance 与废锅流程相比，可以节省净化后的煤气循环系统、废锅和飞灰处理系统的巨 大投资；简单的流程操作可靠、故障率低。对煤化工项目，粗合成气夹带的水 蒸气可以满足变换需要 Cost saving, simple process is more reliable, lower fault rate. Steam in the raw gas could reach the meet of shift for coal chemical projects.
