【正文】 ict the large range of explosion, but due to overpressure simplifies the explosion process makes forecasting precision affected. But the correlation model are mostly rely on experimental results, and the typical model including TNT equivalent model, TNO model and so on. Because mixture bustible gas explosion mechanism and Because mixture bustible gas explosion mechanism adopts greater difference to TNT explosion, TNT equivalent method is not adopted for the damage effect analysis[11]. The risk assessment by World Bank remend explosion hazards is the simple and tending to safety. (5)Where RL is explosion damage radius (m), Cs is explosion test parameters, the value interval are to , and different values range represent different damage effects, shown in table 4. The other mark39。s investigation statistical data, the burst wave output energy and the total bustion heat ratio, reach % high, lowest is %, the overwhelming majority is lower than %[7]. The explosion energy produced by detonation release can be calculated by formula (2). (2)Where EU is chemical explosion energy (kJ), p0 is standard atmosphere pressure (MPa), Qh is high heating value of natural gas (kJ/Nm3), η is effectiveness factor of the value generally between % and %. The other mark39。s chemical properties are the same but state parameter is changed. Tank explosion energy is not only related to medium pressure and volume, but also medium phase. The process finishes in the instant, so we can see the tank explosion energy is results of natural gas adiabatic expansion[5,6], tank explosion energy can be calculated by formula 1. (1)Where Eg is tank explosion energy(KJ), p is the absolute pressure in the tank reservoir(MPa), V is volume of tank(m3), k is adiabatic exponent of natural gas, methane39。E index method, MOND method of ICI pany, risk evaluation method and so on[4]. These methods can estimate high risk and make risk hierarchies, but for hazard the damage from the scope of the impact analysis involving less. Destruction damage radius evaluation method is adopted to disk analysis and damage radius analysis, and made reference value for urban gas storage area location, construction and safety distance.2 Tank blast energy calculationsTwo main risk factors of natural gas propane tanks are overpressure or demolition and chemica l explosion by gas leakage. But the damage effects and explosion explosion source is directly related to the explosion energy. Explosion energy calculationsTanks39。 pressure is higher and the reserve is bigger. the pressure of ～ are used, but the tanks39。依據(jù)預(yù)測結(jié)果，可將罐區(qū)周圍劃分不同區(qū)域，為實(shí)際工程中罐區(qū)選址、建設(shè)、安全距離確定及安全預(yù)案制定提供參考。通過對儲罐爆炸釋放能量的估算，采用模擬比法結(jié)合TNT爆炸試驗(yàn)數(shù)據(jù)計(jì)算出距離儲氣罐不同距離處爆破沖擊波超壓值，運(yùn)用超壓準(zhǔn)則模擬預(yù)測出不同規(guī)格、儲壓下儲罐爆破破壞傷害嚴(yán)重程度及危及半徑范圍；采用世界銀行推薦的危害關(guān)系式結(jié)合傷害破壞等級分析了天然氣爆炸破壞效應(yīng)并與爆破效應(yīng)比較。detrimental effect。explosion。...../Shop/《銷售經(jīng)理學(xué)院》56套講座+ 14350份資料...../Shop/《銷售人員培訓(xùn)學(xué)院》72套講座+ 4879份資料...../Shop/Evaluation on Environmental Safety Effect of Natural Gas StorageYU Chang1,2,3, TIAN Guansan，WANG Guolei 1 Key Laboratory of Renewable Energy Utilization Technologies in Buildings，Ministry of Education ，Jinan, China2 Shandong Key Laboratory of Building Energysaving Technique, Jinan, China3 School of Thermal Energy Engineering, Shandong Jianzhu University, Jinan, China1. yuch., .Abstract: Based on the constructing of natural gas storage tank, the latent safety to the surrounding environment is paid
