摘要
火灾和气体探测系统的设计通常依据严格的规定性标准进行,然而,在面临火灾和气体泄漏等危险事件时,仍有必要开展定量分析,以便全面地了解和管理潜在的风险.从探测器的性能、属性、布置位置,障碍物影响等方面介绍了火焰探测器性能评估,分析空间覆盖法的优点和局限性,通过空间覆盖分析转向场景覆盖,以及将覆盖分析扩展到气体探测的方案,确保分析结果的可靠性.探讨了面临火灾和气体泄漏等危险事件时量化分析所面临的挑战,提出了一个全新的基本分析框架,帮助化工企业更好地理解和管理火灾和气体探测系统的风险.
Abstract
Fire and gas detection system is usually designed according to strict prescriptive criteria.However,when faced with hazardous events such as fires and gas leakage,it is still necessary to carry out quantitative analysis in order to fully understand and manage potential risks.The flame detector performance evaluation is introduced from the aspects of detector performance,attributes,placement and obstacle influences,etc.The advantages and limitations of the space coverage method are analyzed.The reliability of the analysis results is ensured by shifting from space coverage analysis to scenario-based coverage analysis,as well as by extending the coverage analysis to the gas detection.The challenges of quantitative analysis when faced with hazardous events such as fire and gas leaks is discussed,a new basic analytical framework is proposed to help chemical enterprises better understand and manage the risks of fire and gas detection system.
