【摘要】 分析了天然气以及室内燃气事故的特点.研究了在室内有限空间内发生常规泄漏量的天然气泄漏时,采用导出的泄漏数学模型对胶管脱落造成的泄漏进行模拟,并得出其泄漏浓度随时间的变化规律.分析了点火时间对室内燃气事故的影响,提出了控制消除引火源、防止形成爆炸性混合物以及燃气设施的优化配置等相应预防措施.更多还原

【Abstract】 Characteristics of the natural gas and indoor gas accident are analyzed. Natural gas leak in the indoor space within a limited leakage is researched. By using of mathematical models, derived leak caused by the loss of hose is simulated and the leakage concentration with the changes of time is concluded, impact of the ignition time to the indoor gas accident is analyzed,and preventive measures, such as elimination and control of fire sources,prevention to the formation of explosive mixtures and optimal allocation of gas facilities,are put forward.更多还原
