摘要

摘要: 氢氧燃烧尾气中含有残留氢气、氧气及大量水蒸气, 需经减压、冷凝、充氩、过滤和干燥等预处理后, 方可用组分分析仪对其中的氢氧组分含量进行测量, 这些预处理环节将对测量结果造成不可避免的影响。文中在分析氢氧燃烧尾气组分测量基本过程的基础上, 通过对燃烧室内富氢、富氧和当量比3种工况下氢氧反应的化学平衡过程建模, 以及各预处理过程的分析和建模, 开展了氢氧燃烧尾气组分测量影响因素的仿真分析。结果表明, 组分测量影响因素主要为当前的环境温度, 环境温度越高、测量获得的氢氧燃烧效率越低, 真实燃烧效率则要更低一些。此外, 相同环境温度下富氢工况的真实燃烧效率相较其他工况要更低一些。同时根据仿真分析结果, 提出了提高测试准确率的改进措施。

Abstract: Oxyhydrogen combustion exhaust gas contains hydrogen, oxygen and a large amount of vapor, so preprocessing is necessary before the measurement of the oxyhydrogen component content in the exhaust gas with component analyzer. The preprocessing includes decompressing, condensing, argon filling, filtering and drying, which will inevitably affect measuring result. In this paper, the measuring process of the oxyhydrogen combustion exhaust gas is analyzed, and the factors influencing the measurement of the components in oxyhydrogen combustion exhaust gas are simulated by modeling the chemical equilibrium process of oxygen-hydrogen reaction in the conditions of hydrogen enrichment, oxygen enrichment and equivalence ratio, respectively. And then, analysis and modeling of each pretreatment process is carried out. The results show that: 1) the major influencing factor is the environment temperature; 2) the higher the environment temperature is, the lower the measured oxyhydrogen combustion efficiency becomes; 3) the real combustion efficiency is lower than the measured one; and 4) the real combustion efficiency in hydrogen enrichment condition is lower than that in other conditions at the same environment temperature. In addition, some suggestions are offered to improve the accuracy of the measurement.
