The explosion energy of the storage tank is estimated and the explosion shock wave superpressure values are calculated by using simulation proportionality factor and TNT experimental data. The explosive detrimental effects are forecasted by using the overpressure criterion and the harmful relations remended by World Bank. Take a storage tank with volume of 5000 m3 and pressure as the example, safey distance of the physical explosion is , while the chemical explosion is . This study can provide reference for selecting location, determining the safety distance and the region division.Keywords: natural gas。n 更多資料請訪問.(.....)n 更多資料請訪問.(.....)更多企業(yè)學院：...../Shop/《中小企業(yè)管理全能版》183套講座+89700份資料...../Shop/《總經(jīng)理、高層管理》49套講座+16388份資料...../Shop/《中層管理學院》46套講座+6020份資料...../Shop/《國學智慧、易經(jīng)》46套講座...../Shop/《人力資源學院》56套講座+27123份資料...../Shop/《各階段員工培訓學院》77套講座+ 324份資料...../Shop/《員工管理企業(yè)學院》67套講座+ 8720份資料...../Shop/《工廠生產(chǎn)管理學院》52套講座+ 13920份資料...../Shop/《財務管理學院》53套講座+ 17945份資料environmental safety。explosion energy。safety evaluation 天然氣儲存對環(huán)境安全性效應評價于 暢1,2,3，田貫三，王國磊1可再生能源建筑利用技術省部共建教育部重點實驗室，濟南，中國，2501012山東省建筑節(jié)能技術重點實驗室，濟南，中國，2501013山東建筑大學熱能工程學院，濟南，中國，2501011. yuch., . 【摘要】針對城市天然氣儲氣罐的不斷興建與發(fā)展趨勢的大型化，對于已建和待建儲罐區(qū)對周圍環(huán)境的潛在安全性問題，指出運用破壞傷害范圍評價法可直觀的預測破壞效應。5000m3儲氣罐、?！娟P鍵詞】天然氣；環(huán)境安全；爆炸；爆炸能量；破壞效應；安全評價6 / 61 IntroductionWith the development of natural gas industry, as city load store matchs facilities, natural gas propane tanks are constantly constructed. Compared with the normal pressure tank, natural gas propane tanks39。 working pressure[1,2] is monly MPa, and they are pressure vessels. The specification of single tank tends to largescale, the total volume mostly in 10 tons which is the critical value, and the tank belong to major hazards[3], so the safety problems are very much concerned. The safety can be assessed with danger index method, such as Dow Famp。 demolition physical explosion, medium39。s adiabatic approximation for approximately[2]. According to formula 1, the results of tank explosion energy simulated by different volume are showed in figure 1 and figure 2. Figure 1. Curve: Relationship between explosion energy and tank volumeFigure 2. Curve: Relationship between explosion energy and gas pressureAt the same store presses, explosion energy is proportional increase linearly with the volume. The proportional coefficient is explosion energy coefficient[4]. The higher the store presser, the bigger explosion energy. Calculation results show that explosion energy caused by unit pressure is shown by increasing trend at the same volume. Chemical explosion energy calculationsWhen the natural gas in the tank divulges to environment forming widely range of mix flammable gas, the detonation caused by delay fire belongs to the chemical explosion and the energy mainly es from the pot the natural gas internal energy. Because only part of density located at explosion limit, but only part of this part mixtures only part can have the burst wave destruction effect, its proportion acts according to the scene situation like drain diffusion condition, the bustion reaction efficiency, the climatic conditions and periphery factors and so on. According to explosion accident39。s significa
