本文简要介绍了高压火炬的工作原理,描述了地面高压火炬的构成。以80万吨大型乙烯项目为例详细的介绍了地面火炬系统的工作原理和其控制方案,就现有设计方案中长明灯数量多,燃烧天然气费用巨大的问题提出了几种可能的设计改进方案,在能够保证其安全性的前提下进一步探讨节能降耗的可能。 This article briefly describes the working principle of the high-pressure torch and describes the composition of the high-pressure torch on the ground. Taking 800,000 tons of large-scale ethylene project as an example, the working principle and control scheme of ground torch system are introduced in detail. Several possible design and improvement schemes are put forward in the existing design scheme with a large number of long lights and huge cost of burning natural gas. In the premise of ensuring its safety to further explore the possibility of saving energy and reducing consumption.
