大庆市区天然气管道泄露后果模拟及防火安全对策

摘要

Natural gas as a clean energy is widely used in various fields of industrial production and city life. In order to ensure the fire safety, it’s necessary to study the safety operation of natural gas pipeline. In this paper, combined with running conditions of Daqing natural gas transportation pipelines, calculation software FLUENT was used to simulate the diffusion process after the natural gas pipeline leakage, some data in relatively ideal circumstances were obtained, and some reasonable fire safety countermeasures were put forward according to the data.%天然气作为清洁能源，广泛的应用在城市生活及工业生产的各个领域，但从消防安全工作方面，有必要对天然气管道的安全运行情况进行研究。结合大庆天然气运输管道，利用数值计算软件FLUENT模拟天然气管道在运行过程中发生泄漏后的扩散情况，在相对理想的情况下得到一些数据，并根据数据提出几点合理化消防安全对策，希望有助于消防安全工作。
