- 摘要:
点火控制是硫黄回收装置主燃烧炉安全稳定运行的基本条件。近年来我国新建的硫黄回收装置大多已经配置了自动点火系统。但是由于自动点火过程涉及的顺序控制多、设备配合要求精准，其程序设计相对复杂，故部分自动点火系统因操作繁琐、点火成功率不高反而被安全性较差的手持式点火所取代。为了设计一种安全可靠、操作简单、点火成功率高的自动点火程序，本文通过分析某炼油厂硫黄回收装置主燃烧炉典型的点火过程,从介绍自动点火系统的基本程序设计入手，着重讨论了自动点火程序设计中影响点火成功率和点火安全性的重难点。在自动点火系统程序设计中加入了燃料气-空气切断阀时序控制及配比﹑自动逻辑解锁﹑火焰检测延迟设置﹑吹扫按钮防误触等优化措施，成功提高了自动点火过程的安全性和自动点火成功率，有效减轻了操作人员的劳动强度，取得了较好的使用效果。
In order to design a safe and reliable automatic ignition program for the main combustion furnace with simple operation and high success rate of ignition, the typical ignition process of the main combustion furnace of sulfur recovery unit in a refinery is analyzed.Starting from the basic program design of the automatic ignition system, the influence of the automatic ignition program design on the success rate of ignition is discussed emphatically.The key and difficult points are summarized and the optimization measures for automatic ignition program are put forward according to the practical successful experience for reference of similar design.
