摘要/Abstract

摘要： 针对冷放空作业中的意外火灾、爆炸事故，许多研究单一从冲击波超压方面考虑伤害范围，一旦发生火灾，热辐射强度也非常强，研究不同影响因素下火灾的热辐射伤害范围十分必要。首先，分析放空压力6 MPa和放空速率20×10⁴m³/h时冷放空天然气火灾的热辐射影响范围和冲击波超压影响范围，然后，模拟不同放空速率和不同放空压力下热辐射的影响范围和冲击波超压的影响范围。结果表明，在模拟工况下，放空压力对热辐射强度影响更大，热辐射导致的轻伤距离最远达到269.72 m；在模拟工况下，放空速率对冲击波超压影响更大，冲击波导致轻伤的最远距离达到198.00 m。在实际工程中，控制放空压力和放空速率对减轻意外火灾爆炸事故的后果极为重要。

Abstract: Many researches on accidental fire and explosion accidents in the cold venting operation, only consider the damage range from the shock wave overpressure, but once a fire occurs, the heat radiation intensity is also very strong, so it is necessary to study the heat radiation damage range of the fire under different influencing factors. The influence range of thermal radiation and shock wave overpressure of cold vented natural gas fire under 6 MPa and 20×10⁴m³/h venting rate are analyzed, and then the influence range of thermal radiation and shock wave overpressure under different venting rates and different venting pressure are simulated. The results show that under the simulation condition, the vent pressure has a greater impact on the thermal radiation intensity, and the farthest distance of slight injury caused by thermal radiation is 269.72 m; under the simulated condition, the vent rate has a greater impact on the overpressure of shock wave, and the farthest distance of slight injury caused by shock wave is 198.00 m. In practical engineering, it is very important to control the venting pressure and venting rate to reduce the consequences of accidental combustion and explosion accidents.

Key words: cold vent, gas pipeline, thermal radiation, vent rate, vent pressure, fire, explosion
