热风炉点火系统优化与性能提升

Optimization and performance improvement of ignition system for hot blast stove

为提高shell工艺气化装置配套热风炉的长周期运行性能,提高热风炉一次点火成功率,介绍了shell气化装置配套磨煤干燥工艺;热风炉及点火系统运行的情况和存在的问题。通过重新设计优化点火系统,采用一体化高能点火装置;更换稳焰器材质,彻底解决了热风炉一次点火成功率低、高压点火器易故障、稳焰器易烧蚀、热风炉运行周期短等难题。结果表明:热风炉点火系统经重新优化设计后,热风炉一次点火成功率提高至100%,热风炉长周期运行期间燃烧稳定,减少了合成气配烧,提高了后续产品日产量,增加了直接经济效益。

In order to improve the long-term operation performance of the hot-blast stove equipped with shell process gasification device,the success rate of one-time ignition of the hot-blast stove is increased.This paper introduces the operation of shell gasification process,coal grinding and drying process,hot blast stove and ignition system,and the existing problems.By redesigning and optimizing the ignition system,the integrated high-energy ignition device is adopted,and the flame-stabilizing material is replaced,the problems of low success rate of one-time ignition of hot-blast stove,failure of high-pressure igniter.Ablation of flame stabilizer and short running period of hot-blast stove are thoroughly solved.The results show that the ignition system of hot-blast stove has been re-optimized,the success rate of one-time igniter of hot-blast stove is increased to 100%,the combustion of hot-blast stove is stable during long-term operation,the combustion of syngas is reduced,and the daily output of follow-up products is increased,increased direct economic benefits.
