一种水煤浆冷壁气化炉点火装置
摘要：
本发明公开了一种用于水煤浆冷壁气化炉的点火装置，包括：一水煤浆冷壁气化炉；一嵌套于所述水煤浆冷壁气化炉内的炉膛，所述炉膛内构成水煤浆和氧气燃烧的腔室；所述炉膛端部设置一引导口，该引导口连接一水煤浆工艺烧嘴，所述水煤浆工艺烧嘴通过水煤浆烧嘴接口固定于所述水煤浆冷壁气化炉上；还包括一引导通道，所述引导通道依次贯穿水煤浆冷壁气化炉以及炉膛的内壁，与炉膛内形成的腔室连通；该引导通道内嵌套设置有点火开工烧嘴，所述点火开工烧嘴在引导通道内自由运动。本发明的点火操作简单、系统改造小、成本低、稳定性好、烧嘴使用寿命长。
摘要（英）：

The invention discloses an ignition device of a water-coal slurry cold wall gasifier. The ignition device comprises the water-coal slurry cold wall gasifier and a hearth arranged in the water-coal slurry cold wall gasifier in a nested mode. A chamber for water-coal slurry and oxygen combustion is formed in the hearth, a guide opening is formed in the end of the hearth and connected with a water-coal slurry process burner, and the water-coal slurry process burner is fixed to the water-coal slurry cold wall gasifier through a water-coal slurry burner connector. The ignition device further comprises a guide channel. The guide channel penetrates through the water-coal slurry cold wall gasifier and the inner wall of the hearth in sequence and is communicated with the chamber formed in the hearth, and an ignition startup burner is arranged in the guide channel in a nested mode and moves freely in the guide channel. According to the ignition device, ignition operation is simple, system transformation is small, cost is low, stability is good, and the service life of the burners is long.
