摘要:

利用LGA-4130分析仪对电捕焦油器后煤气中的氧含量进行在线检测,并通过DCS控制系统设置含氧量的上限值对电捕焦油器实行连锁停机,确保电捕焦油器连续安全运行。对该系统进行分析后,在肯定其技术优点的同时指出其缺陷,并提出了改进建议。

Abstract:

Oxygen analyzer LGA-4130 is used for on-line measurement of oxygen content in gas after electro-static tar precipitator (ETP) and for interlock shutdown of the ETP in case of reaching the HH limit of the oxygen value preset on DCS aiming at a safe and stable running of the ETP.The advantages and disadvantages of this analyzing system are studied in this paper,suggestions for improvement are also given.
