随着钢铁企业的发展,各种冶金企业工业建筑的建成与使用,使装置的防火难度增大。同时冶金企业内设有液压站、电气室、电缆隧道、操作室等重要的防火场所,只有合理地设计、安装、使用火灾自动报警系统,才能真正做到及时发现和通报火灾,防止和减少火灾危害,保护人身和财产安全。针对设计实践中的一些问题,如火灾自动报警与消防联动控制系统的组成、选择等进行了探讨。 相似文献

Fire risk in high-rise buildings is of special concern to the fire community, since it is crucial but still technically extremely challenging to significantly improve the current fire fighting capabilities when a calamity happens above the “seven story limit.” In fact, at the moment, there is a lack of effective means for fire fighting in this rare but potentially deadly and costly accidents. To address this problem, in this work we provide a preliminary exploration of a new concept for fire suppression: the use of rotorcraft vehicles for aerial fire fighting in high-rise buildings. If available, such system could effectively support fire fighting efforts conducted with conventional means; moreover, it could provide for one of the very few alternatives to classic systems in certain critical cases such as postearthquake fires. At first, we analyze the operative context with the help of a few reference realistic scenarios which allow for the estimation of some key physical parameters. Next, we evaluate two alternative fire extinguishing technologies, and we identify in the water impulse cannon the solution which seems to be the most effective and compatible with the use on-board a rotorcraft for the scopes considered in this work. The analysis leads us to the identification of a target vehicle as a possible candidate platform for the development of a fire fighting helicopter. Finally, we propose a preliminary design of the fire fighting kit, and we evaluate the handling qualities of the vehicle during operations with reference to the ADS-33 normative. 相似文献
