Abstract

Comparative analysis of the fire and explosion safety in using hydrocarbon fuels and hydrogen as automobile fuel is made. For reliable analysis, it is necessary to take into account the set of all the parameters influencing the fire and explosion safety, including the influence of the composition of multicomponent fuels on their characteristics and the influence of external conditions in cases of both normal operation and emergency; study and comparison of separate properties of fuels are insufficient. Complex analysis of the physicochemical properties of fuels shows that, in case of emergency, the consequences of the hydrogen ejection from the fuel system are in most cases less dangerous compared to the ejection of hydrocarbon fuels. The development of detonation combustion as a result of ignition of a hydrogen–air mixture formed in open space is improbable because of high diffusion ability of hydrogen and impossibility of the buildup of the required concentration. The possibility of wide use of hydrogen as an automobile fuel is substantiated.

汽车中使用碳氢燃料和氢气的安全性分析

摘要

对比分析了碳氢燃料和氢作为汽车燃料的防火安全性。为了进行可靠的分析，有必要考虑所有影响着火和爆炸安全的参数，包括在正常运行和紧急情况下多组分燃料的组成对其特性的影响以及外部条件的影响。 ; 对燃料的单独性能进行研究和比较是不够的。对燃料的理化特性的复杂分析表明，在紧急情况下，与碳氢燃料相比，从燃料系统中排放氢的后果在大多数情况下没有那么危险。由于氢气的高扩散能力和无法建立所需浓度的原因，由于在开放空间中形成的氢气与空气混合物着火而导致爆炸燃烧的发展是不可能的。证实了广泛使用氢作为汽车燃料的可能性。
