气化烧嘴异物堵塞的危害及减少异物措施

Harm of foreign matter blockage in gasification burner and measures to reduce foreign matter

工艺烧嘴是煤气化系统关键设备之一,在系统运行过程中,气化炉烧嘴出现异物堵塞的怡况,导致炉内煤浆和氧气混合不均,耐火砖寿命直接受到影响,严重怙况下耐火砖寿命缩短一半,极大影响了气化系统安全、稳定运行通过探讨异物对系统运行的危害,采取可行措施,可保证气化系统的稳定运行,较长的烧嘴使用周期为企业创造巨大的经济效益。

The process burner is one of the key equipment of the coal gasification system. During the operation of the system, the burner of the gasifier is blocked by foreign matters, resulting in uneven mixing of coal slurry and oxygen in the furnace, which directly affects the service life of the refractory brick. In serious cases, the service life of the refractory brick is shortened by half,which greatly affects safe and stable operation of gasification system. By discussing the harm of foreign matters to operation of the system, feasible measures are taken and the stable operation of the gasification system can be guaranteed, and the long service life of the burner can create huge economic benefits for the enterprises.
