环境温度对车用压缩天然气瓶火烧试验的影响

Influence on Ambient Temperature of Compressed Natural Gas Cylinder during Bonfire Test

环境温度是研究车用压缩天然气瓶火烧试验机理的一个重要因素,因此有必要定量的研究环境温度对火烧试验的影响。在已有火烧试验数据的基础上,分析了环境温度对车用压缩天然气瓶火烧试验安全泄放压力和火烧持续时间两个关键指标的影响,结果表明安全泄放压力、火烧持续时间和环境温度均呈反比关系。

Ambient temperature is an important element for bonfire test of compressed natural gas cylinder. Therefore it is necessary to study the influence of ambient temperature on compressed natural gas cylinder during bonfire test. Based on the testing data of bonfire tests, the relationships between ambient temperature and relief pressure, ambient temperature and fire duration are analyzed. The result shows that both relief pressure and fire duration have inverse relation with ambient temperature.
