Analysis on groundbased inerting performance of a fuel tank green onboard inert gas generation system

摘要

摘要: 在描述一种采用催化燃烧产生惰气来降低油箱气相空间氧体积分数的新型绿色惰化工作原理基础上，设计了绿色惰化系统流程，通过一定的假设和简化建立了其数学模型并进行了求解.将结果与采用中空纤维膜产生富氮气体的机载惰化系统进行了比较，结果显示：当绿色惰化系统中抽吸气的流量与中空纤维膜惰化所产生富氮气体流量一致时，前者惰化效果远好于后者.同时，还研究了催化反应器效率和预热气体抽取比例对绿色惰化系统的影响，结果表明：提高反应器效率可有效缩短达到安全氧体积分数所需的时间,且最终油箱气相空间氧体积分数会降低，而选取合适的预热气体抽取比例可以减少系统能耗.

Abstract: Based on the description of the operating principle of a green onboard inert gas generation system (GOBIGGS), which could decrease the oxygen volume fraction on ullage of a fuel tank via the injection of the inerting gas produced by a catalytic combustion reactor, a GOBIGGS flow was designed and its mathematical model was setup. GOBISGGS was compared with the onboard inert gas generation system (OBIGGS) in which the inerting process was realized via the injection of the nitrogen enriched air (NEA) separated by a hollow finer membrane module. The result reveals that if the flow rate of the exhaust gas from the fuel tank in GOBIGGS is identical with that of NEA in OBIGGS, the inerting effect of GOBIGGS is much more positive than that of OBIGGS. Additionally, the performance GOBIGGS affected by the efficiency of the catalytic combustion reactor and the allocation proportion of the preheating gas were investigated. It is found that the increase of the efficiency could shorten the inerting time to the maximum safe oxygen volume fraction and reduce the ultimate oxygen volume fraction, and the power consumption of the system could decrease if a proper allocation proportion of the preheating gas is chosen.
