东方石化有机化工厂地面火炬在运行中的改进

火炬燃烧可以处理生产过程中产生的可燃性废气。地面火炬采用分级燃烧控制、燃烧塔和新型燃烧器，可以达到处理负荷范围大，燃烧完全、不冒黑烟、无光污染、无热辐射、低噪音的运行效果，是一种环保的火炬气处理方式。实际运行中出现了火炬燃烧器不能相互点燃、火炬水封罐超压、火炬气管线和水封管堵塞、长明灯运行不平稳等问题，技术人员通过设备改造和摸索运行参数，上述问题均得到了有效解决。提出了减少长明灯个数，以节约天然气的可能性，讨论了提高地面火炬分级控制可靠性的方法。

Operation Improvement of Ground Flare of Beijing Organic Plant of Dongfang Petro-Chemical Company

Flares can burn out waste gas from producing process. The ground flare uses new type burners, burning tower and a separating burning control system to get a good method to deal with waste gas. It has advantages of wide scale in dealing capability, burning efficiently, no smoke, no light pollution, no heat radiation and low noise. So, it is an environmental friendly process to deal with the gases. There were some problems in running of the ground flare, such as the burners unable to light each other, the gas pressure of water seal tank of torch being over its safe pressure, the blocking of torch gas pipes and water seal tank pipes, and the pilot burner unable to move properly. By the development of equipment and adjusting of running date, these problems were solved. The possibility of reducing the number of pilot burners to save nature gas was raised and the methods of promoting the reliability of the separating burning control system discussed.
