液化石油氣的使用在現代人的生活中已是不可或缺的能源,與民眾的日常生活是密不可分,為了方便運輸以高壓液化方式在道路上載運,然而一旦發生槽體的爆炸則影響層面非常大,常常會造成重大人員傷亡。本次論文的研究方向在針對消防救災人員應變時的作為為主軸,收集有關BLEVE的文獻資料,並個別對於BLEVE所產生的輻射、震波、破片危害對搶救人員的影響作討論,得出初步數值。然後輔以消防人員進入搶救成敗幾個因素1.冷卻水水量2.車輛停放距離及佈線方式3.冷卻水供應延續性4.消防栓供水可靠程度,綜合上述結果製作消防人員搶救20噸LPG槽車的進入時機動作流程圖提供初期指揮及搶救人員一個較為符合現況的建議,希能對於現今搶救此類型災害之人員有所助益。 最後的章節中進一步探討防護LPG槽體作為,針對冷卻撒水水量部分,製作火幕管採實火測試。並配合投射方式仿效固定式射水瞄子冷卻LPG槽體,以輻射熱標準計(heat flux gauge)及熱電偶 (thermal couples) 溫度計得出結果,修正新的冷卻撒水密度為原來固定式冷卻撒水設備實驗想法(水膜溫度為100℃)設計放水密度粗略為1.25倍以上的關係。
LPG is a very important energy for living. The effect is broad and serious when the accident of transportation truck takes place. This research focuses on developing an appropriate emergency rescue procedure for fire fighters to respond a LPG truck fire. The radiation, shock wave and fragment effects are explored in BLEVE scenario of a LPG truck fire. Water density, Safe distance, cooling water supplement, and reliability of hydrant are analyzed to obtain a proper situation of LPG fire rescue. A series of tests were performed to obtain a higher required water density for preventing BLEVE of LPG truck fire in this research. Heat flux gauge and thermal couples are used to measure the cooling effect of water spray in steel heating tests. 7.5 water densities are required to cool the LPG fire based on the tests of this research.
