我国的煤炭资源储量丰富，油、气资源相对不足，对洁净能源的需求日益增加，使 煤化工这个新兴的行业有了难得的发展机遇。煤化工的基本转化工艺就是煤气化，而决 定煤气化炉能否稳定运行的关键因素就是烧嘴的寿命，烧嘴运行中对冷却水系统监控不 到位，极易引起烧嘴破裂引发生产事故，做好烧嘴冷却水系统的监控和管理对煤气化领 域具有重要的现实意义。 气化炉烧嘴冷却水监测的主要手段就是判断冷却水中是否有 CO，如果有 CO 就证 明烧嘴冷却水盘管已经出现裂纹导致炉内煤气进入，需要及时停产避免造成重大事故。 但随着装置运行时间的增加，在线 CO 分析仪经常会出现误报警和故障，造成操作人员 不能正确判断当前烧嘴运行情况，只能依赖分析化验工去现场取样检测，人工检测该指 标时效性差，无法指导生产。本文针对德士古气化炉烧嘴冷却水监控系统进行分析，提 出优化设计方案，将传统的单台烧嘴冷却水系统对应单套在线 CO 分析仪的方式进行改 进，通过增加专门改造的六通阀切换系统，配套安装管路，能使三套气化炉烧嘴系统的 在线 CO 分析仪进行在线切换，解决在线分析仪故障时的监测问题，并对在线分析仪的 切换控制进行研究，通过对 PLC 编程及利用组态王编写上位机界面来实现烧嘴冷却水 系统监控要求。 课题设计的方案对现有在线 CO 分析仪进行了充分利用，可在增加很少成本的基础 上大大提高在线仪表的可靠性，解决出现报警后依赖人工检测费力且时效性差以及存在 安全隐患的问题，并通过优化后的上位机界面，综合分析烧嘴冷却水的流量，温度及压 力，能为烧嘴运行的监控管理提供更好的依据，保障气化炉的稳定运行。 关 键 词：气化炉、烧嘴冷却水、在线分析仪、监控系统

Our abundant coal resources, the relative lack of oil and gas resources, increasing demand for clean energy, the coal chemical industry in this emerging industry has been a rare opportunity for development. The basic conversion process is the gasification of coal chemical industry, coal gasification and decide whether the stable operation of the key factors is the life of the burner, the burner operation of the cooling water system monitoring is not in place, the burner can easily cause rupture caused accidents, do burner cooling water system monitoring and management has important practical significance to the field of gasification. The primary means of gasification burner cooling water monitoring is to determine whether there is water cooled CO, CO to prove if there is a cooling water coil burners have led to the furnace gas into the cracks, the need to avoid a major accident promptly discontinued. But with increasing device uptime, online CO analyzers are often false alarms and faults, causing the operator can not correctly judge the current burner operation, only to rely on laboratory analysis work site sampling inspection, manual measurement of the timeliness of poor data unable to guide production. In this paper, Texaco gasifier burner cooling water monitoring system analysis, design optimization, the traditional single burner cooling water system corresponding single set of online CO analyzer mode is improved by increasing the specially modified six through the switching valve system, supporting the installation of the pipeline, enabling online CO analyzers three gasifier burner system for online switching problem solving monitor fault line analyzers, and switching control line analyzer study Through the use of PLC programming and configuration king preparation of PC interface to achieve burner cooling water system monitoring requirements. Subject to the existing online program designed CO analyzers were fully utilized in very small increase in the cost basis of greatly improving the reliability of the online instrument to solve the reliance on manual detection alarm occurs after laborious and time-poor, and there are security risks issues, and through optimized PC interface, a comprehensive analysis of theburner cooling water flow, temperature and pressure monitoring and management for the burner operation provides a better basis to ensure the stable operation of the gasifier.
