太阳能光热电站有关消防设计问题的探讨

Design Discussion on the Fire Fighting for Solar Power Plant

[目的]为太阳光热发电站不同于常规发电厂的系统,制定安全可靠、经济合理的消防设施设计标准,以保障电站的建设和安全运行。[方法]利用现行的国家规范、标准,对太阳能光热电站采用的熔融盐、导热油的特性及其系统设备、建(构)筑物耐火等级进行分析判别;对电站采用的辅助燃料系统和消防给水的有关特殊消防设计问题进行分析探讨。[结果]分析判别固态单体熔融盐火灾危险性为甲类、熔融态熔融盐火灾危险性为戊类,导热油火灾危险性为丙类,熔融盐、导热油系统建(构)筑物的火灾危险性为二级,根据火灾危险性等级提出具体的消防防火措施。[结论]对电站采用熔融盐、导热油的火灾危险性类别分析判别结果符合现行的国家规范、标准,为太阳能光热电站工程的消防设计提供借鉴。

[Introduction]For solar thermal power stations,which are different from conventional power plants,develop safe,reliable,economical and reasonable design standards for fire protection facilities to ensure the construction and safe operation of power stations.[Method]Utilize the current national codes and standards to analyze and judge the characteristics of molten salt and heat-conducting oil used in solar thermal power stations,their system equipment and the fire resistance rating of buildings(structures);Analysis and discussion on special fire protection design issues.[Result]Analysis and judgment:the fire hazard of solid monomer molten salt is Class A,the fire hazard of molten salt is E,the fire hazard of heat transfer oil is C,and the fire danger of molten salt and heat transfer oil system building is second-level,and specific fire prevention measures are proposed according to the fire danger level.[Conclusion]The analysis of the fire danger category of the power station using molten salt and heatconducting oil is in accordance with the current national norms and standards,which provides a reference for the fire protection design of solar thermal power station projects.
