燃气采暖热水炉的风险评估

Risk Assessment of Gas-fired Heating and Hot Water Combi-boilers

介绍使用欧盟标准中的风险评估模型对燃气采暖热水炉进行风险评估的方法。该方法量化评估风险,评定风险等级;使用故障树分析法,分析风险的来源;根据风险的等级和来源,采取相应的风险防控措施。风险防控措施按可靠性分类,不同等级的风险应采取不同可靠性类别的风险防控措施。以一个案例具体说明燃气采暖热水炉风险评估的方法。

A risk assessment method of gas-fired heating and hot water combi-boilers by using the risk assessment model in the EU standard is introduced. The method quantifies the assessment risk and evaluates the risk grade,uses the fault tree analysis method to analyze the source of the risk,and takes the corresponding risk prevention and control measures according to the grade and source of the risk. Risk prevention and control measures are classified according to reliability,and different grade of risk should adopt risk prevention and control measures of different reliability categories. A case is given to illustrate the risk assessment method of gas-fired heating and hot water combi-boilers.
